computer hijacked, IST bar, unknown users

I sent my hijack this log yesterday, but I don't see it anywhere & I have no posts listed :blink:

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.

Many Thanks,

Kathy Kutay :whistling:
