Some odd activity on my machine sent me on a hunt. Began with a d/loaded zipfile, NOD said it was OK, but as it contained a small executable, I scanned this, & again NOD said it was OK. When I clicked on the executable, the file "disappeared" from its folder, and I became suss. Fired up WinPatrol, which told me a new program had been added plus a restart command, whch I of course disallowed, then began my hunt. I found ZoneLockup.exe [19KB] in my running processes, its date was 24/7/04, so I ended task. Then I found the same file & date in Program Files in TDS3, also in my temp folder, so I deleted these. When I fired up TDS3, it stalled each time when it got to Memory scan started. AdAware wouldn't start at all. Then Windows said that "warpigs.exe" had performed an illegal & was to be shut down. Found 2 of these, one in C:\ which I deleted, & another in C:\Windows\System which I couldn't delete or rename - access denied. TDS3 worked now, & kept saying that it can't read this locked file. A full NOD scan then showed - Warpigs.exe – Win32/trojanDownloader.Agent.AO trojan C:\program files\Defence\xDtnamic\TDS.Unpk\zonelockup.exe –Win32/Hackerarmy.Ztrojan And the 2 in the recycle bin are C:\Recycled\DC1.exe – Win32/Hackerarmy.Ztrojan Dunno why NOD didn't tell me anything amiss in the 1st place, but at least it cleaned them all up after the full scan, apart from the original zipped file in My Docs, which I'll delete. Are these trojans seeing as TDS3 didn't find them?
