Thats True, its probably a trial, but heres some actual help.
Remove Mcaffe all together, un-install that crappy software, never think about it again. It uses way to much resources from your computer and it bugs you every mintute with something.
Heres the good part.
Go to GRISOFT.COM
in the search field at the top, do a search for AVG FREE
select the first link that says AVG FREE EDITION FOR WINXP/VISTA.
Scroll down and look to the left next to the Check marks.
Slect the download for the free version.
when the screen opens, click the download version 8.0 and when its done, install it and run the updates.
Its all easily installed and requires little on your part. Its a completely Free with no adds or junk, Anti virus.
I have used them for 8 years and have never regreated it.
They design Network Server anti Virus software but have the free version for personal computer. Its great and it runs smooth and discreet in the taskbar. Any other questions, let me know.
heres the direct link if it makes it easier.
Good luck and enjoy.
