Do you use Yahoo! services? If not, get rid of this:
O2 - BHO: Yahoo! IE Services Button - {5BAB4B5B-68BC-4B02-94D6-2FC0DE4A7897} - D:\Program Files\Yahoo!\Common\yiesrvc.dll
O2 - BHO: (no name) - {724d43a9-0d85-11d4-9908-00400523e39a} - C:\Program Files\Siber Systems\AI RoboForm\roboform.dll
You have two of those. Get rid of the one with no name.
Do you use the MSN toolbar? If not, get rid of it:
O3 - Toolbar: MSN Search Toolbar - {BDAD1DAD-C946-4A17-ADC1-64B5B4FF55D0} - C:\Program Files\MSN Toolbar Suite\TB\02.05.0000.1105\en-my\msntb.dll
You may also want to get rid of anything with a O8. However, note that if this causes problems, you can restore any of these. Just let us know if doing this causes problems with a certain program.
Ditto for all O9's.
That's at first glance. I am not certain this will fix the problem, but it might, and it will make Windows run faster.
