Hi mrapi,

Normally avast! should detect this as Win32:FakeAV-EAI.
Did you check for avast! shield detection?
It is a detection for a rogue/fake security tool (trojan)

Hi polonus,thanks for the answer,I couldn't find any setting for shield to add rogue/fake
That trojan should be detected by default,it acts as an antivirus and stops any  application execution and asks for money to disinfect...

The file being studied is a Portable Executable file! More specifically, it is a Win32 EXE file for the Windows GUI subsystem,
not necessarily malicious, may provide a threat!

Someone is not following the threads here, see: http://forum.avast.com/index.php?topic=124252.0
Not so safe as was reported here: http://www.isthisfilesafe.com/sha1/F4991FB4740AB85B45EEBB5DD33D39DD88AAEB11_details.aspx
Side effects:
   • Registry modification

 Files It copies itself to the following location:
   • %temp%\Updatea.vbs

Threat considered low damage, avast could detect this as PUP/riskware...
