Memory Cleaning

We press the "Windows" + "R" keys and in the command prompt that you type "MSCONFIG". In the flying menu, go to the "Auto-loading" point and remove the checkboxes from the programs strangers. Usually there are antiviruses, some drivers and a number of messengers, but if you do not use something from this list - feel free to remove, it will be easier to put a tick, rather than guessing that it is preventing PC to work in full force.

Finally

After our tools have discovered and removed unreasonable guests, you should make several final strokes:

• Clear the basket so that the infected file cannot rebel from the dead and cause damage to the operating system;
• To get acquainted with the registry in which in a few clicks to get rid of all programs that you do not use, for this you need in the HKEY_CURRENT_USER / Software section to click on the DELETE button for excess software.

Remember that careless work with the registry can damage the operating system, and therefore it is better to carry out this phase of cleaning under the leadership of the Comrade fully competent in this matter. Remember that often the presence of viruses in your computer cannot be noticed on external signs, and therefore it is necessary to carry out such checks on a regular basis and the more often the better. And again we remind you that the presence of a paid antivirus is not a luxury, but necessity, especially for people who store important data on their device. It is better to pay a few dollars and feel protected, rather than constantly endanger the performance of the PC and the safety of information on it.

Be sure to everyone who worked for a network for some time will definitely collide with the question: how to clean your computer from viruses? First of all, you download a good antivirus (i.e. any free, such as Avast) with a new anti-virus base, for deeply checking all hard drives on the presence of this rubbish and various programs that can harm the computer.

Before checking, it is advisable to go into a safe mode, often the computer fails because of infecting any dirtyness, but because of the program failure or system. To enter the safe mode when rebooting, hold down the F8 key, then your black screen appears in front of which there will be a selection menu, there you will find the above-mentioned computer loading mode. Security mode will start your computer without downloading many drivers, it will provide high-quality anti-virus check. Why is that? The fact is that antivirus in the usual boot mode of the operating system will not check many programs and drivers, as they are currently involved by the operating system.

If antiviruses were checked with such files with simple booting of the operating system, then the operating system would be briefly out of order (hang, reboot, operating system errors, etc.), thereby not allowing anti-virus test. For this reason, antivirus manufacturers have banned antivirus access to these files when they are used by the system.

Often one antivirus may not replace the virus present, try using the Dr.Web Cureit utility, you can download it from the Internet, i.e. Clear the computer from viruses for free and spend a second-time check, usually infection is if it is. So, you download to your computer utility t. The page opens.

Click a hefty green button "Next". And I am surprised (arranged red), that if you enjoy free, then this utility will gather a bunch of information from your computer and departs the owner of Dr. Web. If we refuse to send statistics, then we press the button "I refuse to send statistics" and you are deprived of downloading free utility. And if you agree to send data about your computer - press another button, download the utility and check your computer. We agreed. A license opens.

I celebrate the checkbox "I accept the terms of the license agreement" and click the "Continue" button. The executive file is downloaded cureit.exe.Run it . We see a window. Jump "Run"

We put a tick - agree. Click "Continue".
Click a hefty "Start Check" button. Here is the check and started (already viruses are found).
And we see the result:
Well, then everything is clear: Press the button to "neutralize". Often viruses are sitting in the autoload of programs. Therefore, let's see and clean the autoload of programs. To do this, click Start - Run, and run a word in the form where it is written "Find programs and files". Next will open the window in which and click on

You will see the system setup, you need a startup section. The programs are marked by a check mark, can be infected, or right among those programs you can find the Trojan program or the virus itself, which without your knowledge is loaded into the system. Most often such files are infected (C: WindowsINF * .exe /% windir% System328353.exe and C: WindowsSecuritySmss.exe /% windir% system32smphost.exe), on this path we can see where there is a malicious downloadable object

Remember, you installed these programs, if not installed, then tick the checkboxes from them. One of the most dangerous viruses is svchost.exe, he knows how to issue himself for the necessary programs and services that uses a computer. The task manager has about six such services, if this file is available in the autoload mode, delete it immediately, since this file should not be present in the autoload. Very often, programs that can harm the operating system are in the folder to restore the system (Windows), you will have to delete the entire folder. You also need to clear folders with temporary files (Temp, in each operating system the folder name can be different), and Internet bookmarks pages, etc.

To clean up temporary files and Internet tails, use special programs (for example, CCleaner) that are cleaning the Windows registry, correct errors in the registry and the operating system itself, etc. Often, experts are joking, just reinstalling the system and the virus will not. It usually helps, but if you have little time, and not hunting re-install all programs, it is better to use in another way. First, download several antiviruses.

First, install and update one, and spend them scanning system, after which you remove the first antivirus, and in the same way install the second, etc. Since one antivirus may not see the infection, and the other can find it. It is advisable not to put two antivirus at the same time, it may cause conflicting, as each of the antiviruses will consider itself the main thing. This can lead to large spending of computer resources (RAM, strong load on the processor, etc.), which will depend on the hang or strong braking of the computer.

If you have a lot of information on the computer and you do not hunt a half day to spend on anti-virus check, put a computer for checking at night, and in the morning you already look at the antivirus report. Usually social network viruses are in the Hosts file, in which there are many different lines. Special attention should be paid to 127.0.0.1 Localhost if the infection falls in it, then it will be unusual inscriptions that you have not met before.

This leads to the blocking of the site for example, social networks. If you have such problems pay attention to the hosts file that is located C: WindowsSystem32DRIVERSETCHOSTS, where the virus could add its data in the strings to be deleted, and access to the site will return. In most cases, the problem of cleaning a computer from viruses proposed methods is successfully solved. Good luck!
