I went online to find out how to remove the virus, since Avast! won't,
you say avast have moved it to virus vault..... well, then avast have removed it

anf if it is infected and moved to chest, the there is nothing left for Malwarebytes to detect

win32:evo-gen [[b]susp[/b]]
suspicious ..... if you think the detection is wrong, right click the file in chest and upload to avast lab as possible false detection

then wait a day or two, right click the file again and rescan it, if not infected you can restore it
