By the way, do not forget to regularly scan and devices that you connect to a PC (phone, USB flash drive, MP3 player, external hard drive, etc.) - the information that is contained in them can easily steal the virus.

If everything is already too neglected or the virus is extremely ingenious, then you can return the PC to life by reinstalling the operating system.
