We are running Virus Scan 8.7 (patch 2) with the anti spyware plugin. We haven't really deviated from the default install settings. All clients are running XP SP3.
We have found that we are getting around 1 PC per month infected with fake anti virus software. The latest one is called "Antivirus Antispware 2011". The source of infection is generally compromised web sites.
The mcafee does not seem very good at picking these up and preventing infection. Once the machine is infected i generally have to use tools such as malwarebytes and combofix to clean the machine.
Can aybody advise how i can tweak virus scan so that it prevents these infections? Also, are there any MS patches available or other tools i should be using?
