Greetings. I have been having some recent problems with my computer lately, and avast! is sending out all these alerts stating that there is a threat detected/trojan horse blocked/malicious url blocked, so on and so forth. I have done a MalwareBytes scan, and it has detected that svchost.exe is the Trojan at work. I will provide a log of the mbam log that was completed roughly 20 minutes ago. Malwarebytes Anti-Malware (Trial) 18.104.22.1680 www.malwarebytes.org Database version: v2012.08.12.01 Windows 7 x64 NTFS Internet Explorer 9.0.8112.16421 Mike :: MIKE-PC [administrator] Protection: Enabled 8/12/2012 9:17:19 AM mbam-log-2012-08-12 (09-46-09).txt Scan type: Full scan (C:\|D:\|) Scan options enabled: Memory | Startup | Registry | File System | Heuristics/Extra | Heuristics/Shuriken | PUP | PUM Scan options disabled: P2P Objects scanned: 290235 Time elapsed: 21 minute(s), 48 second(s) Memory Processes Detected: 1 C:\Windows\svchost.exe (Trojan.Agent) -> 3452 -> No action taken.

(end) I have some computer experience, and I have gone to the last resort of backing up uninfected personal files to an external storage, and wiping the hard drive and formatting it. After the format and reinstall of anti virus programs and such, it is still showing that the trojan is there. If you require additional logs from Avast! or from another source, please let me know.
