I have detected some parasite(name: ISTbar/Powerscan) reside in my registry key :
1) HKLM\Software\Classes\Typelib\{1bcd446e-7095-11d0-9c4e-00aa00bdd685}
2) HKLM\Software\Classes\Interface\{1bcd446b-7095-11d0-9c4e-00aa00bdd685}
3) HKLM\Software\Classes\clsid\{1bcd446c-7095-11d0-9c4e-00aa00bdd685}

Can someone please tell me how to remove them?? Thanks a lot...

try installing and running Lavasoft Ad-Aware and Spybot S&D. I have both on my PC and between them they catch mostly everything. Spybot is free and Ad-aware has a free version.

You can find them at
Spybot - http://www.safer-networking.org/en/index.html
Ad-Aware - http://lavasoft.element5.com/support/download/

Not sure where you got these, but I think they are false hits. If you look at the data underneath the typelib entry, at least on my system, it shows D:\Program Files\Microsoft Visual Studio\Common\Tools\APE\REGTOOL5.DLL. Also the guid used does not appear in any manual uninstall of ISTbar (see http://pestpatrol.com/ms/pestinfo/i/istbar.asp for more info.)

You NEED to have Ad-Aware 6 and Spybot 1.3 installed. Try System Mechanic too, works great.

Yes, but if you use this product to remove it, Visual Studio stops working.

These registry entrie are part of Microsoft Visual Studio and are nothing to do with ISTbar/Powerscan.
