Hi I've been a bit suspicious about my comp quite a while now. First off, a user on this computer downloaded and opened a few weird .EXE files. These seemed to be game patches but one of the lot got the eye of my AVG anti-virus which said it was a trojan. The name of the exe was also suspicious: "Cracktro.exe"... If I do have a virus now it's quite seemless, I don't feel I'm lacking performance anyways. Secondly, I noticed that the gibberish-named folders located straight under C/ were duplicating (not long ago there was one where now there was three). My quick research showed me that these were probably files for windows update and that they could be deleted. I accidently moved one of these folders into another (damn my cheap mouse!) and after that only one folder could be deleted as the one inside the other one could not even be accessed/opened anymore ("C:\gibberish is not accessible. / Access is denied."). All in all, the contents of two folders were deleted but one was left into some kind of mess. I've now introduced myself to techspot and hijackthis, now bringing to you my "Crusty.exe" log... PS I've noticed that AVG isn't a very highly approved anti-virus program. Is there really a significant difference in quality between AVG and one of the highly recommended programs like Avast or Avira? And would it be good to install Windows Defender as well (with a quite thorough anti-virus already installed...)? For spyware I have so far used Malwarebytes. I'll appreciate any help. Thanks!
