Okay thank you very much! The program found less viruses this time, and I have qurantened them, but not emptied the quarantine yet. I'm wondering though, someone told me to go under settings and uncheck "Always scan extra and heuristics objects" is that correct? Anyway, here is the new log: Malwarebytes' Anti-Malware 1.39 Database version: 2428 Windows 5.1.2600 Service Pack 3 7/14/2009 1:17:19 PM mbam-log-2009-07-14 (13-17-19).txt Scan type: Full Scan (C:\|K:\|) Objects scanned: 158702 Time elapsed: 58 minute(s), 9 second(s) Memory Processes Infected: 0 Memory Modules Infected: 0 Registry Keys Infected: 2 Registry Values Infected: 1 Registry Data Items Infected: 0 Folders Infected: 0 Files Infected: 1 Memory Processes Infected: (No malicious items detected) Memory Modules Infected: (No malicious items detected) Registry Keys Infected: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{a20a380b-a3d0-4e10-b029-5e6fb5031dba} (Trojan.Vundo.H) -> Quarantined and deleted successfully.
