I have always fully updated NIS 2010.
every time during last months I start kaspersky Virus.Win32.Sality removal tool ( http://support.kaspersky.com/viruses/solutions?qid=208279889 ) and it always made corrections (sometimes different fixes) to my win xp sp3 (32bit):
Why kaspersky tool always fix my system files, what scripts it blocked?
Once I saw "4" number in one of now "0" string
Norton is not capable to detect the active Virus.Win32.Sality.aa, Virus.Win32.Sality.ag (by Kaspersky) infection or always updating during last months Special Removal Tool from Kaspersky Lab is always missing (and they are not know that they doing, while writing the Tool)?
Second variant is possible, but hardly probable.
Is there professional comment about this or again only just users will answer to it?
