Hi all, I've spent the entire day trying to figure this out, and it's been driving me absolutely nuts. I currently have McAfee Total Protection and it kept popping up trojan.zeroaccess. It asked me to restart so it could fix the problem and it appeared to do so. This seemed to keep popping up random ad windows primarily from ad.xertive.com and then it stopped. Soon after, it happened again. I found a post in here http://www.techspot.com/community/topics/infected-with-trojan-zeroaccess.184669/page-2 and it seems that the user was able to solve the problem with the help of some of the forum members, so I signed up for an account with the hope that someone will be able to help. It eventually came to a point where there were 47 trojan viruses found, and then mcafee would automatically fix it or quarantine them and it would come back to 0. It seems that the viruses are being found after about 30 minutes of being online... I downloaded malware bytes and did a full scan and 3 objects were detected. The mbam log looks as follows: Protection: Enabled 9/11/2012 11:21:34 AM mbam-log-2012-09-11 (18-52-41).txt Scan type: Full scan (C:\|) Scan options enabled: Memory | Startup | Registry | File System | Heuristics/Extra | Heuristics/Shuriken | PUP | PUM Scan options disabled: P2P Objects scanned: 668299 Time elapsed: 6 hour(s), 36 minute(s), Memory Processes Detected: 0 (No malicious items detected) Memory Modules Detected: 0 (No malicious items detected) Registry Keys Detected: 0 (No malicious items detected) Registry Values Detected: 0 (No malicious items detected) Registry Data Items Detected: 0 (No malicious items detected) Folders Detected: 0 (No malicious items detected) Files Detected: 3 C:\$Recycle.Bin\S-1-5-18\$0777cfe37d3bfd5a401954926157210b\U\00000001.@ (Trojan.0Access) -> No action taken.

(end) If someone is out there, I can post the GMER log as well. Please give me a shout or if you have a solution, please let me know. Thank you!
