Noel, I cleared the logs on 1/23. I'm sorry it's been a while, but it's difficult finding several undisturbed hours in a row to dedicate to my computer. I've got too many irons in the fire, including helping the parents while you're helping me. Here is what I've done:
WinMail - I could not remove the referenced folder since it didn't exist when I tried. It seems to be self-resolved.
WordPerfect - I started the process of repairing this at 1:40pm on 1/27/13. I removed it and reinstalled it. During the install of the product and a service pack, I received several errors that are in the log file exactly like the Adobe error when "writing to a file". Then it asks that I verify I have access to that directory. On each error, I merely clicked "retry" and the installation continued. In every instance I checked, the referenced file or directory didn't exist when the error occurred. I completed the repair just after 3:00pm. Any errors after 3:20pm would be actual errors we might be concerned with.
Adobe - See WordPerfect explanation
Netlogon - I disabled the service.
Firefox - I don't understand the error and am not seeing the error in the current logs. These errors could have ended up self-resolving with successive updates of Firefox.
DistributedCOM - My errors didn't exactly match the error on the page to which you linked, but after several searches, I happened to end up in the same place. I did find another page that seemed like a better fit for my particular circumstances (
DescriptionEvent ID: 1016 appears every 10 minutes. Unable to - Microsoft Community), but the fix seemed a bit too general. I followed the instructions on the page to which you sent me and it appeared that each step was already done up to step 12. I checked Local Launch and that's it. This was 5:05pm 1/27/13.
Scheduled Tasks threw an error and when I went into Task Scheduler, I got this error: "The task image is corrupt or has been tampered with.ManualDefrag". It was the only error I found.
The System log shows multiple
Dhcp-Client errors that occur only while I'm VPN'd into my office computer or off the network.
The odd DNS servers you noted are correct. I've been trying out the OpenNIC servers.
