Problem with Antivir

Hope someone out there is an expert with this. I'm using the personal classic version for XP. I'm generally very happy with this product, except that:

The program creates numerous pop-up warning messages. Most, if not all, relate to Trojans, and the message asks me to determine whether to delete, wipe (whatever that is), allow, deny access, etc. It defaults to deny access, but I usually select delete.

It gets so bad, at times, that the puter is almost unusable. Can be very irritating.

Is there a way to set the program so that it doesn't show the pop-up warnings? Can I just set it to delete all such files without the warning messages?

Any help is greatly appreciated.

By the way, I tried the support forum on the Antivir website, but it's mostly in German, the sign up process is in German, so I'm pretty lost there.

Also, internet provider is Cox Cable. Very fast, but very wide open.
