Currently trialling SuperAdBlocker, which has resident SuperAntispyware protection engine included. I have a week to decide whether or not to buy SAB. So far it's performing flawlessly with these other resident protection programs: - Comodo V3 Firewall with Defense+ HIPS activated. - Comodo BOClean 4.25 - NOD32 v2.7 My only criticism is that SuperAdBlocker processes use about 43K of system memory. It's performing very well at blocking ads, and website-loading speed is noticeably faster due to ad-blocking. Any suggestions for alternate ad-blockers? Thanks for your help!
