Thanks for any advice.

Have you tried doing your scans in "Safe Mode"?

Are you using two anti-virus programs?

Using more that one anti-virus program is not advisable even if your using one of them as a stand-alone on demand scanner. Even when one of them is disabled, it can affect the other. Issues can arise when the active anti-virus detects the non-active one's definitions or quarantined files.

The primary concern with using more than one anti-virus program is due to conflicts that can arise when both are running in real-time mode simultaneously. Anti-virus software components insert themselves into the operating systems core and using more than one can cause instability, crash your computer, slow performance and waste system resources. When actively running in the background while connected to the Internet, they both may try to update their definition databases at the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.

Each anti-virus will often interpret the activity of the other as a virus and there is a greater chance of them alerting you to a "False Positive". If one finds a virus and then the other also finds the same virus, both programs will be competing over exclusive rights on dealing with that virus. Each anti-virus will attempt to remove the offending file and quarantine it. If one finds and quarantines the file before the other one does, then you encounter the problem of both wanting to scan each other's zipped or archived files and each reporting the other's quarantined contents. This can lead to a repetitive cycle of endless alerts that continually warn you that a virus has been found when that is not the case.

Anti-virus scanners use virus definitions to check for viruses and these can include a fragment of the virus code which may be recognised by other anti-virus programs as the virus itself. Because of this, most anti-virus programs encrypt their definitions so that they do not trigger a false alarm when scanned by other security programs. However, some anti-virus vendors do not encrypt their definitions and will trigger false alarms if used while another resident anti-virus program is active. To avoid these problems, use only one anti-virus solution. Deciding which one to remove is your choice. Be aware that you may lose your subscription to that anti-virus program's virus definitions once you uninstall that software.

Thanks quietman7. I'll give that a shot. But No, we only have Norton loaded on the PC. We used AVG and Panda's free online scan.

Anybody know if system restore will help or leave us still infected?

That depends on whether or not you have a clean restore point. System Restore will back up the good as well as the bad files so when malware is present on the system it can get included in any restore points. You can give it a try.

Yes we do have restore points prior to the infection so we'll see what happens.

Thanks
