Protect your computer from viruses

Signs of a computer infection

There are signs by which you can understand that a PC or laptop has become a victim of viruses. However, they may differ. Depending on the purpose of the malicious software. But the general signs do not change.

If some of the above signs are found on your computer, then you should scan your PC for viruses as soon as possible. Otherwise, the infection will continue and turn into a pandemic. Therefore, an urgent need to install some kind of antivirus. Let's consider the best.

Content

Increasingly, users are attacked by Trojans, malicious files that change browser or system settings, constantly display advertising sites or viral ads. Windows protection does not always work, and it becomes necessary to clean your computer from viruses for free. This can be done in several ways.

How to check your computer for viruses

Threats can enter the operating system via the Internet, along with someone else's flash drive, or when installing dubious software. The development of antivirus products has led to the emergence of more cunning, sophisticated spyware or malware. Now they can be written to autoload, automatically restored after deletion. It becomes more difficult to cure a computer. Here are ways to clean your laptop from viruses yourself:

1. The most radical, tough way to clean a computer from viruses is to reinstall the operating system. Together with malicious files, files from system partitions or from a logical drive will be completely deleted. This means that the programs and documents that were on it will be lost. You can save data on other drives, but there is a risk that the infected file lives on them as well.
2. Disk formatting. A good way if you know that the virus is not in section C.
3. Return to a restore point without malicious files. The operating system is able to roll back to its previous state, for example, yesterday, when worms or Trojans have not yet penetrated into it. When using a backup, all new files, folders will be deleted and replaced with old ones. Suitable if only system data and directories were affected.
4. Use any good antivirus, for example: Doctor Web (Dr.Web), Kaspersky or Nod32. The scanner will detect threats, offer to delete, treat or quarantine them.

Some viruses are not so easy to clean: they open browser windows with advertising pages, perform hidden actions. One of them is blocking the work of anti-virus utilities. In such cases, online services for the initial launch of the scan can provide assistance. Here are some popular and effective options:

• BitDefender QuickScan - online check via a cloud service is enabled right on the site;
• Panda ActiveScan - a special module will be loaded, which will check the computer for security threats through the cloud service;
• HouseCall - searches for spyware and viruses online;
• Microsoft Safety Scanner - a one-time check from the company;
• Kaspersky Security Scan - computer virus treatment is carried out by a special utility. It needs to be downloaded, but the software works through a cloud service.

The best utilities for cleaning your computer from viruses

Full-fledged antiviruses are better suited to clean your computer, but you can also use special utilities. The best ones are listed below:

1. DR WEB CUREIT is a simple free portable utility. You just need to run the program and click "Start Check". This may take from 1 to 6 hours (according to the number of objects being checked).
2. NORTON SECURITY SCAN is another additional protection tool that will help clean your computer from viruses. Distributed for free. It works and is available to the user online, controls the PC in real time.
3. Kaspersky Anti-Virus is a full-fledged program that is distributed for a fee. There is a special utility that you can download for free - Kaspersky Security Scan.
4. AVZ is a powerful, popular utility that allows you to solve even the most complex pest problems. Very useful in cases where you can not log into Windows. Run it in safe mode when the system boots. The current version is updated automatically free of charge.
5. ESET ONLINE SCANNER is another option on how to clean your computer from viruses for free. Installation is not required, you just need to download and run the executable file.
6. AVIRA REMOVAL TOOL is not the best option for cleaning a computer from viruses, but they use it because the utility is distributed for free.
7. Avast! VIRUS CLEANER TOOL - additional protection against Avast antivirus. Works offline in the cloud service. Looks for and removes spyware, malicious files.
8. Malwarebytes is a very effective adware removal program that successfully hides from Kaspersky or Dr.Web. The first month you can use absolutely free, but then you have to purchase a license.

How to clean your computer from viruses yourself

If you wish and have free time, you can clean the computer yourself. It is recommended at the very beginning to delete everything from the trash, use the CCleaner program, which will destroy unnecessary and unnecessary information from the registry, all kinds of garbage. The easiest way to clean your computer from viruses is to format your hard drive. If it is important to save data on it, you should choose a more difficult path, using antivirus and special programs.

Cleaning and Formatting the Hard Drive

It should be understood that cleaning a disk and formatting are two different things. The first is more often carried out in order to free up space on the desired partition by deleting junk, temporary and broken (non-working) files. This action does not directly affect the removal of malicious files. You can execute it as follows:

1. Go to "My Computer".
2. On the disk that needs to be cleaned, right-click.
3. Select "Properties".
4. In the window that opens, find the "Disk Cleanup" button at the bottom and click on it.

Formatting completely deletes all the contents of the section along with the malicious code. Be sure to copy all important data to temporary media. To perform you need:

Confirm all items, click "Run".

When finished, go to the "Tools" section and click on "Process Manager". Delete everything that is not highlighted in green.

Go to the "File" menu section and click "Troubleshooting Wizard". Clean up the system.

These first steps on how to properly clean your computer from viruses will allow you to identify problems in the system, the location of infected files and neutralize them, but not delete them. You need a full-fledged antivirus program. AVZ is preparing the ground for its efficient operation. Select full scan and wait for the results. All found threats must be removed. If, after that, ads continue to load, pages open spontaneously, use Malwarebytes.

How to remove a virus without antivirus

Alexander Antipov

Do you know how to return the state of your Windows to a point in time when it was not yet infected with a virus? This can easily be done without antivirus and, in addition, it can take only a few fractions of a second.

No matter how far you have gone down the wrong path, come back.
Turkish proverb

Introduction

It is very interesting to watch people who, realizing the presence of a computer virus on their Windows operating system, hold a competition: which antivirus is better. All antiviruses in a row are used from the Internet or from an existing disk, until the next one says that the virus has been found and cured. However, this method does not always give the desired result, and then the person reinstalls the operating system and calms down.

Do I need to use antiviruses? Necessary. But at the same time, one must understand that antiviruses do not always catch viruses. For example, let's take a recent report by SurfRight where 107,435 real computers were examined. 37,898 computers (35% of all) were infected with malicious code, while 25,038 computers had antiviruses installed at the same time as viruses, but the antiviruses did not know about it. As you can see in this example, 2/3 of the infected computers (25038 out of 37898) had an antivirus, but this did not help them. It's good, however, that on other computers, having an antivirus has helped. Thus, an antivirus is a part of protection, necessary but not sufficient.

Note: in this article, by “virus” we mean “any kind of malicious code”

Computer security specialists refer to malware by various names, depending on the tasks that the code in it solves for the attacker. For example, the task of the classical computer virus- inject into another code or replace it. task rootkit is to hide its presence in the system. task Trojan is to steal some data. task ransomware is to encrypt your files or block access to the system. task network worms is to spread its code over the network. Etc. Often, attackers combine all these tasks in one module of a malicious program, and it is simultaneously a network worm, a Trojan, and a rootkit, and to cover it up, it is also a screensaver or a fake antivirus. In the literature, all of these types are sometimes referred to as "malware" to shorten the expression "malicious code". I don't like the neologism "malicious", so I don't use it. In this article, the word "virus" is used as a typical example of any malicious code. Therefore, reading the word "virus" in this article, we understand: "any malicious code."

Do I need to reinstall Windows if the malicious code is not removed or detected in any way? Yes, this is one of the options. But the disadvantage of the Windows reinstallation method is that the installation takes time: after all, you need to install all the necessary drivers, additional software, such as Microsoft Office, and so on, or it can take all day (or all night).

Of course, an inquisitive reader already knows that it is not always necessary to reinstall Windows if you have created an image of your system (backup) in advance using specialized programs, a typical representative of which is Norton Ghost. However, there are other even faster methods that allow you to return the state of the computer to a point in time when it was not yet infected. It's time to learn how you can speed up the process of returning your operating system to this state.

Windows restore checkpoints

A lot of problems could be avoided if home users worked with minimal privileges, but all the correct words of the security people about this are shattered by real life. Any home user trying to follow this simple helpful tip will run into Windows messages that you need to be an administrator to recognize a new flash drive, you need to be an administrator to burn a DVD. And in the end, he spits on useful advice, turns on administrative rights and continues to live happily, and, interestingly, for a long time, since modern malware does not harm its keeper for the time being, until the appropriate command is received. But when the command is received and you are asked to send an SMS to a short number or transfer money for decrypting your own DOC files, it’s definitely time to act.

Working with minimal privileges is not a panacea for all ills

Periodically, Windows finds ways to elevate privileges to administrator. For example, even this year a vulnerability was found that allowed one to become an administrator on both Windows XP SP3 and Windows 7. The description of the vulnerability can be found at CVE-2010-0232 (http://xforce.iss.net/xforce/xfdb/55742 ) Thus, even when working with minimal rights, you do not have a 100% guarantee that malicious code will not be able to get administrator rights. Therefore, it is recommended to disable vulnerable services and install component updates for all versions of Windows at all times.

Before you start treatment, you need to remember the day when you could get infected. It could be, generally speaking, visiting any site, downloading any program, viewing any PDF or video on the Internet, sticking a USB flash drive into a USB flash drive, attacking from a nearby computer. Now you can get infected everywhere, even on quite decent sites and even by viewing completely harmless documents: PDF, XLS, DOC. You don't have to be afraid of choosing a date: even if you make a mistake with the date, you can always roll back the changes or choose an even earlier date. By default, System Restore in Windows XP and Vista saves system files and the registry once a day, while Windows 7 saves once a week.

Then you launch the standard System Restore utility from the Start menu and return the system to its pre-infection state by entering the desired date in the appropriate program window. A system restore point is information about the state of the system at a specified date and time. Therefore, by selecting the desired restore point, you can restore the state of the system to that moment. That's all. I repeat: if the treatment was unsuccessful, then you can roll back the changes back or choose an even earlier restore point.

WindowsXP.

Here is what the screenshot looks like forWindows 7.

When restoring in Windows 7, you can view the programs that will be affected by the restore. In Windows XP, System Restore only monitors a key set of system files and applications, while in Windows 7, the system monitors the entire drive for changes. However, in both operating systems, user files are not included in system restore points, so going back to a previous point will not result in the loss of your documents.

In Windows XP, if you stored documents in the My Documents folder, they will remain safe and sound, but the desktop will be returned to its previous state, and system files, including the registry, will be restored. In Windows 7, neither the My Documents folder nor the desktop is changed by a restore.

If you are reading this article before you are going to use restore points, then check if you have this feature enabled - this will help you restore the system in the future in case of any emergency. In Windows XP select: My Computer - Properties - System Restore, in Windows 7: Computer - Properties - System Protection.

Windows SteadyState or disk snapshot

An even better free system restore feature that comes with Windows is the SteadyState component. It is available for Windows XP and Vista and must be downloaded from the Microsoft website and installed separately. Windows 7 does not have this feature as of this writing (May 2010). In principle, third-party developers also have similar solutions, I will list them: ShadowUser, Deep Freeze, Renurnil, Shadow Defender. Some of them also have free versions. And some of them also work under Windows 7.

Windows SteadyState and other similar systems were originally developed for use on public computers in hotels and Internet cafes. But this technology is also very useful for home users as a system to keep Windows up and running.

To understand how all such systems work, you need to imagine that your Windows starts up and takes a snapshot of all the information on the disks and then runs not on your real disk, but on this copy of the disk, it is called a shadow copy. It's as if you made a backup and worked on it, instead of a real disk. You can change and delete anything on this shadow copy, but your real disk will always remain unchanged. If you feel that it's time to "treat", then you can simply press the reset button and Windows will boot again from a "clean slate", that is, from an unchanged copy of your disk. You spend 0 seconds cleaning the system.

Naturally, in order to remember all the changes on the copy, Windows SteadyState needs some disk space. For this, a special cache file is allocated and used, the size of which you can adjust. All "changes" that are not actually made to the disk are written to this file. In similar products listed above, there are more original solutions when the available space free from files on a real disk is used, where information about changes during operation is stored. When restarting, all this information about changes is reset.
Screenshot where hard drive protection is enabled.

Thus, the advantage of Windows SteadyState is that you can cure any changes that have occurred in the system by simply restarting the system. The downside is that you have to take care of the safety of your documents that are stored on your drives. Because Windows SteadyState only protects the partition where the system is located, you can store documents on adjacent partitions. And if you store your documents (or movies or music) on network drives, then you will simplify your life even more. It should be noted that the third-party products listed above offer more advanced functionality of this type of protection, but at the same time they ask for money for it.

Disk images

Speaking of recovery systems, one cannot fail to mention the way when you can make a regular backup of your system and then restore it. Disk backup systems have evolved a lot: they can already backup a running system - without wasting your work time waiting for the process to complete. Created Windows backups can be restored even to a completely different computer, where there will already be a different hardware: processor, motherboard, video card, etc. However, I consider the fastest way to restore is to work on instant disk copies, when by a normal reboot you completely erase the consequences of your erroneous actions . And spend 0 seconds of your time erasing the virus.

Conclusion

So, we have studied several ways to restore the system after infection. The fastest way to restore an infection is to work on a shadow disk image, the slowest way is to restore from a backup. However, all of these methods are faster and more reliable than any antivirus, especially when protecting against types of malicious code such as rootkits. Rootkits are specifically designed to hide from antiviruses and very often antiviruses are unable to resist them. It is on the basis of rootkits that entire networks of remotely controlled computers (bots) are built, and antiviruses and people do not even notice this.

Example: TDSS rootkit (also known as Alureon, Tidserv or TDL3)

I give an example of this rootkit, because in my environment I found a lot of people infected with this rootkit, and these are both commercial and government. organizations. The method of infection in the cases I have identified is autorun from a USB flash drive. Antiviruses do not detect this rootkit, the best way to find it is . Based on data from Damballa, it is believed that Zeus is currently the largest botnet designed to steal passwords for Internet banking systems. But in Russia it looks like TDSS. To check, run this utility for yourself, what if it finds something with you too?

A feature of the described methods of protection (as well as many others in our life) is that we still have to prepare for a possible virus attack - if you did not think in advance and did not turn on the built-in protection system, then it will not work. See for yourself: are restore points enabled, install Windows SteadyState, create a backup of the system. Do any of these simple steps and you will not have to regret later and restore your computer to working capacity for a long time. I also recommend that you take extra care of the security of your Windows and configure it according to security recommendations. At least turn off, finally, autorun viruses from flash drives.
