After my Virus Scan 9 expired, I started to get messages that "mcupdate.exe" required me to connect to the Internet. Now, a month after installing Virus Scan Ver 10 I still get these messages. Should this happen, and if no what can I do. Thanks.

Although it's for auto updating McAfee, it's so persistant about not being removed. I don't like software that reinstalls itself.
