Your ESET NOD32 Antivirus is out of date. What does this mean? ESET NOD32 Antivirus or ESET Smart Security has stopped updating. What to do? What does the message "You will not be able to receive the latest virus signature updates" mean?

Computer literacy

After much trial and error, I noticed the “Check for Viruses” function labeled on Windows installation discs. 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 the contents of hard drives and a lot 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 set the BIOS to boot from the drive and clicked Start to launch the scanner. When the scanning was finished, I selected everything that DrWeb found and deleted the “enemies” from the 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 against any virus threats to 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 is another convenient way to 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 boots, you need to run the DrWebCureIt.exe executable file and wait until the application finds malicious files. You'll have to be patient for many hours, 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 actions 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 currently in use and cannot be deleted!”, you need to reboot into safe mode again and repeat the procedure.

Having returned Windows to its native full-fledged mode, you need to go to the Task Manager (Ctrl-Alt-Delete) and turn off processes that are 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-partitioned hard drive, save an image of the system disk (using Acronis software) and, if necessary, replace the virus-infected system disk with its original image.
