It's possible it's freezing on a zipped file but Technical Support would have to check that, they are free to phone or use online chat and linked under Useful Links at the top of this page.
First try running the Virtual Technician to make sure the software is OK. http://mvt.mcafee.com/
If that doesn't help try uninstalling McAfee via Control Panel > Programs and Features
Then run the MCPR cleanup tool and reboot.
Reinstall from your online account.
If that doesn't help then try Technical Support.
By the way, when you ran chkdsk I hope it was with the /r modifier as that corrects errors - chkdsk /r
hi,thanx for the fast reply. the virtual technician found no problems. sorry, forgot that to write in the first step.w Will try the chkdsk/r the next days. then uninstall and reinstalling. when i did that last time i had some trouble with the licence counter. could you describe the steps in logical order please? sorry for the layout - i am with the mobilr phone online. .. greetings tibema
The uninstallation via Control Panel should decrement the account automatically but if you are out 1 license then phone (or use the online chat) Customer Service to have them free one up. The link is under Useful Links at the top of the page also.
