You can’t use that as any sort of confirmation as the VBS:Malware-gen is a generic signature designed to catch new versions of a particular type of malware. So what was being alerted on could be entirely different in each case.

There are if you browse the viruses and worms forum, many such cases of users reporting false positives, but by the end of the topic most are found to be good detections.

MBAM won’t find anything as it isn’t even looking for that sort of thing any way, plus you are scanning your computer and the avast alert effectively blocks anything getting on the the system.

Whilst generic signatures are a fine balance between not catching new variants or detecting something that is good, but avast in the past has been very accurate. So each case really has to be investigated on its own merits.

In this case there certainly is something strange going on with this number of obfuscated scripts outside of the closing HTML tag a standards no, no.

So whilst this is ongoing:
