False Positive Problem Probably Solved
Exploit-MhtRedir.gen Detection Should Be Fixed
I've discovered what I'm pretty sure is the root problem of the detections of Exploit-MhtRedir.gen on this blog. The detection was limited to McAfee VirusScan and was due to the program misinterpreting quoted text as malicious code. There was no infection in the page, and at no time did this quoted content (which was from a Secunia alert) present any security risk to visitors of the blog.
I'm trying to work out why VirusScan detected the code but not other antivirus programs, and it appears to be a case of VirusScan using a more general detection string. If you receive any detection from this page, please feel free to tell me about it.
