See first post again

We're on a free 1 mth trial with Mcafee that automatically was provided with this computer,so we supposedly have security-no info given on this except :30 days trial OEM listed on our order form.
When this expires we have to transfer NORTON over to take over from Mcafee-only using norton again cos we've just renewed it in june and dont want to waste the money we spent in renewing it.
But when i was noseying around in Control panel i found a section that said "SYSTEMS DIAGNOSTIC REPORT" and this is where it said that the security centre is not recognizing that we have antivirus installed.
I dont know if it was like that BEFORE Dell disabled our background programs?
