Ok, I don't know if Avira Antivir PE Premium is too powerful or not but it found 6 or so suspicious contents which NOD32 didn't, and I deleted them. After restart the PC, first thing pop up is Avira found another trojan; c:\windows\system32\gebya.dll and one other, I forgot the name. No matter which action I select, it seems that Avira just can't do anything about this infection. So the screen just stays there and windows explorer couldn't even load up. So after an annoying process, I finally got it removed and did a system restore, but it wasn't successful. So now Avira is gone from my system but it's MESS up! This all happen last night and here are the symtoms I've found so far: 1, When I tried to play an .avi file with WMP, a "an internal application error has occured" pop up. 2. System Tools, System Restore, the page didn't come up. Try to open it again, all I got is a blank page. 3. some of the links in my favorites now can't even open that specific web site. Blank page. 4. After clicking on a link at a certain web site, it will not proceed to that location. Also, in Isohunt.com you know how the page drops down and reveals the torrent file after you click on the name, well it didn't that. 5. This is the worst, I still got this damn thing in my system. Can someone give me some pointers here and restore my PC back to what it was 7 days earlier. Howard helped me to clean up my PC last week, it was running very good (major thank you), and now I'm infected again. How the hell can someone get infected twice with different BS within a week. Any advice will be greatly appreciated. Side note: screw Avira, hooray for NOD32.
