Hi,

My friend had bought a HP PC 1 1/2 yrs back. He had got a Mcafee total securityfree with it for 3 yrs. At that time he had already running Avast Pro version and did'nt used it. But now when he installed the antivirus, it got activated but the problem is the software is the old one compaired to their new total security.

Is there any way to upgrade it ?

Secondly, I am using IE8 and everytime I log in to hotmail or gmail etc it says that the security certificate is invalid and when i install the certificate, it still shows the error. Pls tell a way to get rid of this certificate error?

My internet settings are now on low (option).
 
I think he can upgrade the AV to the new one as he have bought it. And about the second one, i have no specific answer, better switch to a different browser - opera
