If you keep an eye on the Avira forums, both look to be a false positives. You are best keeping them in quarantine, until it's confirmed. For future reference, it's best to only post in one forum at a time, instead of posting here and in Computer Help. You said you have Avira installed and the virus is stopping the installation of AVG free. Only one anti-virus is required. Two may get you into trouble and may also be the reason you couldn't install AVG.
I need help in removing this virus. my avira anti virus turns off everytime i try to quarantine/remove the virus. it is also stoping me from installing other antivirus such as AVG free.
I also got this virus that came with HEUR/EXPLOIT.HTML which is TR/Dldr.Zlob.AADO.S i remove it from ccleaner where it has been lurking.
