Hi there, I have a netbook which has become quite badly infected in the last few weeks - I have always had AVG installed on my computers and this is the first time it has failed me. I installed AVG Free Edition 2011 a couple of months ago and as soon as it was on, it alerted a couple of problems. The problems it has been finding are: Win32/Patched.FR - affects Winlogon.exe and seems to have created a couple of Winlogon duplicates Win32/Patched.FS - affects Explorer.exe and seems to have created a couple of Explorer duplicates Trpjan horse Patched_c.JHC - not found in most recent AVG scan, but was in the last one (ran on Friday) and was affecting either Winlogon or Explorer I did switch over to a fresh copy of Explorer.exe using RegEdit but I can't delete the old virused one. Had planned to do a factory rebuild using the pre-loaded recovery tools - there is an option to reformat with this - however, when I ran it, the Netbook restarted (as expected) and then after starting the recovery popped up an error on the dos Blue-screen (ie doesn't even get back into Windows OR the Recovery Program) saying "c0000137 privilege failed". I can get the Netbook to load into Windows again OK, but obviously recovery is not (currently at least) an option. I'm guessing the virus have come down when we've streamed something, but not sure what. Hoping someone can offer some assistance, Thanks, Chris.
