I am sorry if you found it; I don't want to make extra work. I appreciate any assistance you can provide.
This started months ago -- computer slow. anti-spyware listed IST bar, removed but it returned.
What I have done: traced bar to contentmatch.net, then it kept coming back in a series of "mirar" items. All on restricted list.
I have used Spyblaster, Spybot search & Destroy, Ccleaner, Adaware, Free AVG virus & spy removal. I purchased Spysweeper (which will no longer load) and Zone Alarm Pro.
The registry is seriously compromised (some of which may be my doing, stupid attempts to repair) RPC is gone.
I tried all the things suggested before posting. SuperSpy fixed 48 registry errors the others found nothing.
Panda would not load. Now I am unable to copy & paste and sometimes it won't let me sign in in Safe Mode.
Please read Hijack Log and see if this is fixable. I really appreciate that you take the time to do this, you are chalking up much good karma.
