I have a Win 7 64 bit Toshiba (6 months old) and have been happily working along - until Dec 12, 2012.
There was a windo update and a McAfee update - and then my laptop kept freezing (such as IE would open, but never display a page content, adn ctl alt del would go to main screen but never show task manager).
I have tried several things over the past few days - and it appears my pc only runs normally if I delete McAfee. I have been a user for years, and I love the product.
I thought I would try here before calling - not really prepared to pay for special service when I have never had a problem before - I know it is not a virus or malware (several packages this).
Anyone else had this - or can some one offer help. I currently have one subscription of mcafee available (deactivated from this machine) - all others seem OK, though one other win7 laptop is now also running very slow, esp in IE.
I assume that was a 12.1 version update. Ok you took it off try running MCPR after the windows uninstall and then reboot and run
and reinstall from your account
Sometimes an update does not work as well as a clean install. try that and report back. Support is available as well link in useful links tab above. If you still have an issue they need notifying.
