Hello
Diat68 and welcome to the 'Pool. It sounds like you would need to uninstall the McAfee virus protection, then install it again. You can do this in the Control Panel utility "Add-Remove Programs".
1) Click Start
2) Click Settings (you may not see "settings". If not, just click control panel)
3) Click Control Panel
4) Scroll to the McAfee product and select it (a single click on it)
5) Click the "Add-Remove" button
6) Complete the Add-Remove Wizard steps
7) Restart your computer to complete the process.
Once the uninstall is completed, reinstall the McAfee.
By the way, I'm not a fan of McAfee anti-virus. If I were to list the virus protection programs I like best the order would be:
Norton Anti-Virus 2003
AVG (Grisoft)McAfee
For the firewall, I really like the free ZoneAlarm. You can download the free version
by clicking here. Look on the lower right of the page, under "Direct Links".
I hope this helps!
