What operating system & service pack is this machine using and how much RAM and free hard drive space does it have?
If you want to run the Virtual Technician again and post a session ID# I'll get the techs to look at it.

You maybe should have ruin the MCPR tool again, or even tried it in Safe Mode. It's just possible that there are still remnants of an old version interfering. What version was installed before anyway?
You should also do the following.
If you are running IE7 or 8 go to Tools/Internet Options/Advanced and click Reset. Then click Apply and OK. Close IE and reopen it. Re-enable all add-ons under Tools/Manage Add-Ons.
If you are using IE6 go to Tools/Internet Options.
Under the Security tab make sure all zones are at default, under the Advanced tab make sure it is at default, Apply and OK it. Under the General tab clear history and temporary files.
McAfee relies on IE to function correctly so that may fix it.
You may also wish to check for infection using the free versions of these two tools and have them clean anything they fine. http://www.superantispyware.com/superantispywarefreevspro.htmlhttp://www.malwarebytes.org/mbam.php
