When I try to run a hard drive scan with the "scan archive files" box checked, the scanner stops on one file around 2000-8000 files into the scan. While scanning that file, I watch the memory drop down to 3-10mb left (out of 256, normally maintains 130-140). And it just acts like it is scanning that file forever. It tends to get stuck on the same file, but not always. If I rerun the test, it may stop on a different file and do the same thing. HOWEVER, when I leave the "scan archive files" box unchecked, the scan works perfectly.
No other antivirus software is installed. Any help would be appreciated.
