HELP: AVASoft Antivirus Professional Fake Software Infection

Created: 19 Mar 2013 • Updated: 21 Mar 2013 | 4 comments
This issue has been solved. See solution.


I have a client who appears to be infected with the AVASoft Antivirus Professional rogue/fake anti-virus software.  The SEP client's definitions were updated, today, prior to the infection, as they are dated March 19, 2013.  I cannot find information about this, within the Symantec website; so, is there any information relating to the detection, cleanup, etc. of this infection, using a Symantec Endpoint Protection 11.x, unmanaged client? 

When the system is booted up, the infection disables SEP from the system tray, as the user can see the SEP system tray icon disappear, upon system start; then, the AVASoft Antivirus Professional system tray icon appears.  I have instructed the person to boot into SAFE MODE and run a full system scan.  So far, the unmanaged SEP 11.x client can start in SAFE MODE and is scanning, which is good, because the SEP 11.x client cannot start when the person boots, normally.

Therefore, any KB, technical notes, tool, etc,. would be greated appreciated; thank you.

Hi Volron,

Putting IPS into place on SEP is very effective against FakeAV.  AV alone is not enough for complete protection.

Hope this helps!

With thanks and best regards,

Consider Using Symantec Power Eraser when:

An outbreak on a small number of workstations or windows servers

Symptoms seen of Fake/Rogue AV such as:
  • A reoccurring pop up notification
  • Alerts indicating that they are infected
  • Prompts to register (buy) the solution
  • Fake Blue Screen Of Death messages

I would suggest you to work on the below Articles:

Using Symantec Help (SymHelp) Tool, how to Collect the Suspicious Files and Submit the same to Symantec Security Response Team.

How to troubleshoot FakeAV if it is not detected
