Your description makes it appear as though you no longer have a valid subscription to download McAfee's updates.. Is that correct or not?
If it's not expired and assuming you have a good internet connection,then RIGHT click on the McAfee icon, choose "Update Now" should do the trick..
If it's expired, the answer is to purchase a valid extension to your subscription.. The Suite has a number of items that need updating, (unlike the old VirusScan of old which was a single program) and therefore, it needs a number of items to update fully.
Hope this helps and let us know more.
I have a Windows 2000 SP4 and I am having a little trouble with McAffe. It has an icon in the system tray saying your computer is not protected and I opened it up. It says The "Detection Signature is over 30 days old" "Action Required" "Click Fix now" I tried pressing fix and it says "Fixing your protection Items--Please wait" And it says that for about a few minutes then it goes away and nothing happens. Is there a way I can fix it or manually fix the detection signature?
