I should have replied before this but I've been busy, and then, after getting concerned that my ailing computer's (a desktop) hard drive might be preparing to crash, I wasted time trying to figure out how to copy valuable personal files to a DVD. Believe it or not, I've never been able to do that. Missing software, missing instructions, or operator incompetence? Don't know. But the laptop I'm working on right now has plenty of info on how to do it and it seems straight-forward. I plan to copy files from the desktop via flash drive, to the laptop, and then get them on DVD. Most of them are camcorder MPEGs which is why they're too much for even an 8GB flash drive.
I ran event viewer per the info link you provided. There are more errors than you can shake a stick at. Hopefully I can give you a good overview. For Applications, there are 1552 events, about 95% errors. First error on 11/23/08, "Faulting application ViewpointService.exe, version 184.108.40.206, faulting module ViewpointService.exe, version 220.127.116.11, fault address 0x00002250." This must be the problem I was having when I first found BleepingComputer.
Later on the same day, there were two more of the same error, then two that say, "Fault bucket 370778352". Then more Viewpoint and fault bucket errors as I progress in time along the list into the next day. Here's a different one, "Hanging application iexplore.exe, version 7.0.6000.16735, hang module hungapp, version 0.0.0.0, hang address 0x00000000." Then on 11/24, there were more Viewpoint and fault buckets, then this, "Failed auto update retrieval of third party root list sequence number from:<http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootsseq.txt>
with error: A connection with the server could not be established." There were more of these errors and viewpoint and bucket errors as I progresss in time until 11/24 at around 5:06 pm. At that time, I must have used quietman7's procedure to get rid of viewpointservice.exe. After that, I don't see any more viewpoint or fault bucket errors. Near as I can tell as I spot-check along the list, the rest of the errors are the "failed auto update" errors as I entered above. The "source" column shows "crpyt32" and every so often there's a warning that says, "reached crypt32 threshold of 50 events and will suspend logging for 60 minutes". Interesting.
For the Security section, there are no errors.
For the System section there are much fewer errors than for the Applications section, but they are from a wider range of causes so there would be more to list. Let me know if you need to see them and I will enter them in another reply. This particular reply is getting long already. If you are able to look at this today, I should be more free to reply promptly.
Also, I just remembered another symptom that I thought you should know. It might be related. My McAfee now persistently says my detection signature file is between 8 and 29 days old. When I click "Fix" as it says, it works on it for awhile, then says I'm up to date, but the initial dialog box that says I'm not protected doesn't change to show that I'm protected. I don't think the fix is happening. Could the reason for this be the same as for why I can't get into BleepingComputer.com?
