Hi, kbz1960, I run Windows XP Home with the SpywareBlaster, Spybot-SD without a problem. Spywareblaster does not require run, it just sets kill-bits to prevent malicious Active-X and sites. BoClean... I have tried it once, and it was much sorta like a Resident Shield. It will not conflict with AVG's Resident Shield. I use ZoneAlarm Free as my firewall. Hope this helps. :euro:
