Hello again, bua ako!
I have checked out the links you have provided and am sorry to report they did not resolve the problem. Details follow:
RE: McAfee Security updates appear to hang and McAfee applications are not able to update through authenticating Proxy servers causing Signature files to be out of date--I only had my MSN dial up service running (the connection speed said 28.8 Kbps)--no other applications were running. I then ran McAfee Update and the red arrow was rotating clockwise. I put my mouse over the rotating arrow and it said downloading McAfee Virus Scan. The percentage completion increased over time until 31% was reached at about 3 minutes into the download, then it was hanging. Then after 10 minutes of download time, I put my mouse over the rotating red arrow and could not believe my eyes--it said 3% completion!! I double checked and yes, it was only 3% completion. Going backwards!!???? Finally, after about 18 minutes into the download, the pop up said an error occurred while updating--please reinstall Security Center.
The above situation occurred AFTER I downloaded the MSCPRXFIX.EXE tool. I went to the web site and saved it to my desktop then double clicked it, ran it, then restarted per the instructions. If I read the file info correctly, it is a 125 KB program file. I do know that normally it takes my PC about 1 minute to download 150 KB, but downloading this tool only seemed to take a few seconds, which seemed odd.
Being a computer novice, I do not even know if I am going through an authenticating proxy server!!
Anyway, these are my objective observations re: above.
In the past, when I got this error warning, I would just un-install McAfee, use the MCPR removal tool, then download from the McAfee web site for Dell, but I feel I have done this too many times and we need to get at the root cause of the problem.
These problems seemed to develop after my PC was only about 14 months old (July 2008). Things seemed ok for a few months, then the problem resurfaced.
Any other suggestions you can offer would be greatly appreciated.
Thanks in advance!!!
