Sorry to say that, but Antivir does not support UPX/FSG at the moment( Maybe in some weeks), but Avast(windowsversion, not Linux) support UPX and some other runtimepackers.

On the other hand, it may take some weeks but than Antivir will have smaller updates.:wink:

I do not know what kind of Malware RejZoR send to Alwill, but maybe it is not necessary to add it asap, in Avasts point of view.
