Hi, I’ve been using SpyWareBlaster for about 4 years now. Found it via SpyBot’s suggestion. I’m running Windows XP sp2 which is a corporate based image, (originally), I’ve received several updates from Microsoft, mostly security related corrections. I run Norton Anitvirus v10.1.6.6010 SpyBot v1.6.0 Microsofts’ firewall along with automatic updates and virus protection are all enabled. I connect to the net via Cable modem. I haven’t had any issues until the latest upgrade, v4.1 I have attempted to go back to version 4.0, but the issue still persists. When I performed the re-Install…I ensured the c:/program files/spywareblaster folder was gone. I attempted a solution, which was to remove: ckdaabase.dtb sbdatabase.dtb sbinfo.dtb This had no affect. I righ-clicked the executable, and clicked run as Admin, and it immediately errors with the message as soon as I chose this, (not sure if this is normal progression?). I also found via another thread...that I had been infected by Viewpoint. I uninstalled this...and no difference. Thanks in Advance!!!
