Not sure what is causing your PC to lock up, unless McAfee's security centre
is causing a possible glitch following your removal of it.
Take a look at the following link for a comprehensive comparison of
different antivirus products...
When you get to the website, click on the 'comparatives' button on the left
hand side. Then read the online results and report for February 2007 and
It should give you a good idea of how the different products perform.
From experience of a range of different antivirus products I would probably
agree with the test results which seem fair / balanced.
