I am having the same issue as explained in this post: http://forums.malwarebytes.org/index.php?showtopic=75011&hl=fonts&st=0 Somehow I got a trojan (perhaps through a Java exploit). I removed the offending file from my startup items and emptied my temp files which seems to have removed the threat. I then ran Malwarebytes which stopped while scanning the Fonts folder (even in Safe Mode). As with the previous poster, when I only scan the Fonts folder it completes without a problem. I tried renaming the mbam.exe file and ran a scan and it completed the scan (by coincidence?) and it found a "Trojan.FakeAlert" registry entry that I had it remove. However, I still have the issue with the scans stopping at the Fonts folder. Its not a huge issue to me but if there is a fix it would be nice to know. I checked and I don't have the two fonts that were mentioned in the previous response. Any idea what is going on here? Thanks. David
