hi, i'm running SpywareBlaster 3.5.1 on Windows 98SE, with Firefox 184.108.40.206. it protects fine for IE and the 2nd one (i believe "Restricted Sites). then it can't do a thing for Firefox, and it shows up in the Task Manager as "Not responding". i also run avast! AV v. 4.7 Home Edition, and Spybot Search & Destroy 1.5.2 Release Candidate. i have SDHelper installed, but *not* TeaTimer. Immunizations are also set. i had had problems with Spybot 1.5.15, til i uninstalled it and installed this current one. i don't know if this affected the working of my SpywareBlaster, as it had been working fine the last time i used it. any idea why this hangs? thanks.
