I am running W2kPro, and noticed that "Prolivation.com" appeared on all my URL's. After a little research I discovered that this is apparently a browser highjacker. The site PC Hell had instructions for removing this, and this involved using Regedit and changing the defaultprefix key under HKEY_LOCAL_MACHINE, which was indeed directing me to this site. I changed the prefix so it just read http://
as instructed and closed Regedit.
Everything was fine for about 24 hours, but now every .exe file or folder I try to open tries to launch IE. Everything has an http://
prefix. I tried to get back into regedit, but the same thing happens. I am at a loss. Any suggestions?
