MALWARE INFESTATION WON''T GO AWAY
Hi Rick, I use Ad-Aware SE Personnel and Firefox. However, I keep getting a malware called "Adware.SystemProcess". Do you know where it originates and whether it is a cause for concern?
Nigel Deller
 
A. No problem, Adware SystemProcess is a persistent piece of malware that hides inside the Registry and latches on to Internet Explorer (yet another good reason to switch to Firefox), it then makes use of your internet connection and fiddles with your Firewall settings to allow it to connect with an outside company (usually ValueClick or one of its affiliates) to display ads in pop-up windows. AdAware should have removed it, however, the specific malware definition was included in update SE1R72, released on the 26th of October, so I suggest you download the latest updates and run it again. Otherwise there are manual removal procedures, (which involve editing the Registry) on the Symantec web site.
