Any idea why AVG 8.0 would hang when trying to scan _default.pif (c:\windows\_default.pif) I recently reinstalled XP Home SP3, and everything was fine at first. Then yesterday, I noticed that an automatic AVG scan had been running for seven hours and was hung on _default.pif. I canceled the scan, did some research on it, and found that others had the same problem (unclear solutions). I ran Trend Micro's House Call, and it found no viruses. The AVG automatic scan hung again today, and now it seems I can't even cancel the scan (tried the program's cancel button, and also Task Manager's End Task). I'm not sure what my next step is and would appreciate any help you can offer. Thanks.
