I recentley got the WIN32.P2P-Worm.Alcan.a out of my system (allong with a few hundred other things that had been lurking in my system). I was relevied to find i had gottten rid of it, but was soon very fustrated. It seems that some system files got deleted, resulting in some of the visual settings missing. FOr example, the theme for Windows XP has been replaced by windows Classic. When I went to change it back to the XP theme, i found it was no longer avalible. i was wondering if anone could help. any help would be appreciated.
