I was using MSE as my anti-virus but recently purchased and installed Avira Internet Security 2012 because it was ranked very high by av-comparatives.org I would like to do some download comparisons with each AV running by themselves. I can do the tests with Avira running alone but not with MSE running alone. If I go into MSCONFIG/STARTUP and remove the check mark beside Avira, and put a checkmark beside MSE, I get a popup message that a program is trying to access the registry etc. if I close out and reboot, Avira starts up anyway. Is there an EASY way to stop Avira from starting, so I can run some tests ?? Thanks, Mike
