My son contracted the Win32/Virut.NBK virus on his PC. I have run absolutelty everything to try and purge this trojan and it cannot be cleaned. I have run ESET NOD32 AV complete scans, I have run MalwareBytes anti-malware complete scans, ComboFix, HJT, and others. The virus lives on. Is there a way to purge this without reformatting my harddrive and reinstalling the OS? If not, does anyone know if it is safe for me to back up his MP3, movie files, JPGS, Word docs, etc. to an external hard drive and re-install on the "new" system without bringing the virus alogn for the ride? Supposedly, it only infects EXE, SCR, and HTML files. But, I'm afraif to go thru all that work and then bring the virus along. But, we don't want to lose all the data files. ANy ideas appreciated.
