ISTbar hijacker toolbar for IE, removal??

I use Firefox, but I mistankenly opened IE instead of my normal Firefox. I still have IE 6 I think and it rerouted me to update to 7 or whatever newest version. I closed IE and a popup for "performanceoptimizer.com" appeared. I pressed ALT + F4, closed 2 more popups that appeared and ran the Firefox Anti-Spy. This browser hijacker, ISTbar hijacker toolbar, cropped up on the scan and I thought I deleted it. But it keeps reinstalling itself.

Ran my Norton AntiVirus Scan and Spybot S %26amp; D in safe mode, but it wouldn't let me run Ad-Aware 07, not even in a regular boot mode. Nothing showed up btw in either sca. Can I just remove the IE from my OS and would this ISTbar remove also or...??

Help please.

Try a program called Hijackthis, it'll find loads of crap in your machine and delete it and it may even get rid of the program giving you issues. Also, you could try CWShredder.

Both of these programs may sort your problem out.

Try to search for files and folders related to this program and delete them as you go. Do the same in the registry too.

Make a system restore point before you make any major changes.
Run GarbageClean from http://www.SecureMyWindows.com to remove it.
