VME=Visible Mutation Engine
These are harmless nonmemory resident parasitic viruses that search for .COM files of current directory and write themselves to the beginning of the file. They do not manifest themselves.

Looks to me like you have a false positive since you have a legitimate version of the enceclopedy. I suggest you pack those two file in a pasword protected zip and send them to virus@avast.com
Don’t forget to mention the pw in your mail :wink:
