hi my subscription to the security center ran out so i went to renew it. i had some trouble installing it and when i clicked on the security center it said i didnt have any antivirus installed so i went and foolishly bought the virusscan plus. now i have sorted out the security center not all of the tempory files had been deleted before i installed the new one, now this is working i tried installing the virusscan plus but it doesn't seem to want to work. is it actually possible to have these two programs running simultaneously. thanks in advance for any help. Chris
