i keep getting this after installing Malwarebytes Anti-malware. Some of the firewall initialization files have been tampered with by an external source. These files have been restored to provide maximum security for your system. You are advised to run an Anti-Spyware product to make sure your system is clean from malware. I run these products everytime i get this message. then under hidden files this message shows, C:\Program Files PC Tools Firewall Plus\Apprule Set.xml why is this appearing, as i ran the free version of this malware product with no problems, yet when i bought it all hell appeared. when i un-installed Malwarebytes my pc ran as before when i was using the free version. How do i correct this fault, as i now have the paid version.
