After six months of no problems with NOD32, Version 3, on WinXP, it started hanging during a manual scan at the System Volume Information folder on the "tracking.log" file. After some searching online, I found that antivirus scans that stall on tracking.log is a common problem. I tried deleting tracking.log in safe mode and letting Windows create a new file, but that didn't help. Only adding tracking.log to the file exception list in NOD32 solved the problem. I couldn't find a reference to this problem in this forum, so I would appreciate any input. 1. Have others here dealt with this problem? 2. Is there any risk in excluding tracking.log from the virus scan? 3. Is there a better fix?
