They allow you to scan your system without installation.

If to your personal computer the antivirus does not install, the very first thing that comes to mind is that you downloaded a damaged installer file from the Internet. For example, the Internet connection was interrupted for a moment.
Typically, soft portals offer several alternative links for downloading files. Try downloading the antivirus installer from a mirror. It is believed that it is best to download programs from the official website of the developer. However, in some cases this path is not suitable. On the developer's websites, you will most often find only the latest version of the antivirus, and your old operating system Windows system XP can easily become incompatible with modern software.
Why not install the inconvenient Eight for the sake of a single antivirus? You can visit alternative sites, which include previous versions programs. For example, the completely reliable resource Majorgeeks.com.
The antivirus does not install, despite the fact that you tried to run installers taken from different sources? Then you need to ask the following question: is it impossible to run only one specific antivirus or does none at all want to work on your computer?
- First check Windows firewall and network settings. It is quite possible that you have very strict access limits and the system simply does not allow software from suspicious sources. And for Microsoft, any manufacturers are suspicious if they have a name other than Microsoft.
- It behaves approximately the same way antivirus program from Kaspersky Lab – only Microsoft products are allowed for installation.
What to do if, on principle, you do not want to install Kaspersky anti-virus software? They say it heavily loads the system and generally intrusively interferes with the user’s personal life. Do you want to visit the site? Internet Explorer with the support antivirus package Kaspersky will not allow you to do this.
Chinese software in recent years They have greatly improved in quality and KingSoft antivirus is now included in the list of the best free ones.
Software compatibility issue
Some antiviruses cannot work properly in parallel on one computer. Known fact, which has long become an Internet tale - NOD and Kaspersky identify each other as viruses and brutally try to destroy the competitor.
To check installation capability additional antivirus, first try disabling the existing one. If installed, you can start checking compatibility.
Depending on Windows versions A specific antivirus program is required. This needs to be clarified immediately on the website from where you are going to download the installer. Please review carefully system requirements. For a normal installation of an antivirus, it may simply not be enough RAM or free space on your hard drive. Or, as mentioned above, a modern antivirus requires latest version operating system.
Files from a previously removed antivirus remain on the system
Such serious antivirus programs as Avast, AVG, Norton are not easy to install on a computer, but even more difficult to remove. When you try to remove some antiviruses, deep mutual connections in the registry are severely broken and this can even lead to complete failure of the computer.
If you want to completely, and without negative consequences, remove one of the known ones, popular antiviruses, visit the official website of the developer and download a special uninstaller utility from there. After removal, thoroughly scan the system with a powerful cleaner. For example, Advanced System Care.
Still can't install a new antivirus?
Virus infection of your computer
There are such cunning viruses that not only disrupt the operation of the computer and steal personal data. They also interfere with the operation of installed antivirus software and prevent new programs from installing. Some particularly malicious viruses do not even allow the user to open pages of sites from which antivirus software could be downloaded.
If it is impossible to install only antiviruses on your computer, but all other programs can be installed freely, there is a high probability viral infection systems.
If the virus does not prevent you from visiting the official websites of antivirus manufacturers, such as ESET, Dr.Web, Kaspersky, then go to the website and run from there antivirus scanning computer. Since the verification will be done via the Internet, the procedure may take quite a long time.
Checking your computer in protected mode
Prudent users download the Dr.Web CureIt healing utility in advance and store it on a flash drive just in case. Or better yet, on a flash drive or CD. For some reason the utility works more powerful from disk.
If you are not one of the prudent types, then try downloading the healing file via the Internet. If your Internet is not working, you can turn to your friends for help. If you have them, of course. If you have no friends, no one has canceled such useful things as Internet cafes and communication salons. Tired of the lack of buyers (due to economic crisis) sellers will be happy to help you.
Now, you have a flash drive with Dr.Web in your hands. All you have to do is log in safe mode and start the treatment process. After this, restart your computer and try to install the antivirus again.
If none of the above helps, all that remains is to format it hard drive and install Windows again.
After much trial and error, I noticed the “Check for viruses” function indicated on the installation Windows disks. If the antivirus can be defeated even before the operating system has loaded, it will not have to be installed from scratch along with the loss of content hard drives and masses of time. On the site of everyone's favorite Doctor Web, I downloaded the disk image, then used Nero and burned the CD. When the image was deployed to disk, you could start working with the antivirus itself. After that I put it in BIOS loading from the drive and clicked Start to launch the scanner. When the scanning ended, I selected everything that DrWeb found and deleted the “enemies” from hard drive. Having returned the BIOS settings and rebooted the system, I realized that the goal had been achieved and that malicious files could be removed from startup via Start-Run-msconfig.
Alas, it is very often impossible to root out cunning viruses from a running OS, but the proposed method will certainly work for any virus threats for the Windows family.
In general, DrWeb is a completely universal product. In combination with “straight hands”, he can treat OSes hopelessly corroded by viruses. There's another one convenient way remove malicious viruses without manipulating the BIOS or burning blanks. The Dr. program will help. Web Cure It, which does not need to be installed - just run the *.exe file. The program can be downloaded from the official website of the product.
Solving the problem of a virus that prevents you from installing an antivirus
So, to start fighting the virus, you need to start the OS in safe mode by holding F8 while turning it on. After Windows boot you need to run the executable file DrWebCureIt.exe and wait until the application will find malicious files. It will take many hours of patience, but it will pay off. It is advisable to follow the progress of the search: Doctor Web will show different files and offer options for dealing with them. Deleting found files should be done with caution; non-specialists should consult with experienced people so as not to destroy part of the operating system. If the OS does not allow you to delete files through an antivirus, you can try sending them to the Trash manually. If, when trying to get rid of a file, a window pops up saying “the file is in at the moment is in use and cannot be deleted!”, you need to reboot into safe mode again and repeat the procedure.
Bringing Windows back to my heart full mode, you need to go to the Task Manager (Ctrl-Alt-Delete) and turn off processes not related to the system one by one. But even here you don’t need to get excited and delete everything, otherwise Windows may simply fail. When unnecessary processes and services are cleaned up, you need to try again to delete the harmful file.
Slightly more advanced users who are in the habit of creating checkpoints before problems with the OS appeared can try to restore the system to its clean state before viruses appeared.
The most enlightened computer owners scrupulously install Windows and all their favorite applications on a clean and pre-divided sections hard disk, save an image of the system disk (using Acronis software) and, if necessary, replace the one infected with viruses system disk in its original way.
There are cases when it is not possible to run anti-virus programs on an infected computer due to active resistance from the virus. For example, the AVZ and UVS utilities do not start or do not work correctly. Antivirus scanners(Dr.Web CureIt!, Kaspersky Virus Removal Tool) find viruses in the system, but cannot cure them. In this case, try the recommendations below.
Program to terminate suspicious processes:
The programs discussed below must be run as an administrator!
KillEmAll- a small utility that terminates all unknown processes in memory, leaving only the necessary ones system processes. It is better to launch it through Windows Explorer, because if you launch using Total Commander, it will also be closed, which is not convenient. The program starts killing unknown processes in memory immediately after it starts. For better effect, after the first launch it needs to be closed and then launched again.
After that, try to launch anti-virus utilities that did not want to work correctly.
Using KillEmAll is safe, and if after starting it the system starts to malfunction, then it will be enough to restart the computer to restore operation.
RKill- another utility to help in such situations. It not only kills dangerous processes, but also restores some registry branches, such as associations of .EXE, .COM, & .BAT files, and also launches some important Windows services, if they were disabled, and cleans the hosts file.
You should not run the RKill utility for the sake of experimentation, but use it only when necessary.
Renaming antivirus program files:
If the antivirus program does not start, then sometimes renaming it helps executable files(EXE). For example, it won't start AVZ program, then its file ( avz.exe) rename to winlogon.exe and try to run it. If that doesn't help, try these options: 346356.exe , 435234.scr , 45243.bat , 45234.cmd , 42342.com , 234923.pif
Running in Windows Safe Mode:
To start Windows in Safe Mode, you need to restart your computer and immediately after the screen goes out, multiple presses keys F8(or F5). Or turn off the computer, then turn it on and immediately press this key.
The menu will load " Additional options downloads".
Select option " Safe Mode". After booting the system in this mode, try running anti-virus programs.
If there are still problems in "Safe Mode", then repeat the operation, but select " Safe Mode with support command line ". After the screen appears black window, enter in it explorer and press Enter- will load Windows Explorer, try running antivirus programs.
