I'm having a peculiar problem that just started yesterday out of the blue. Suddenly when I boot up in Windows 7 (64-bit), there's always an open dat file titled "win403700" that greets me on my desktop. It's of no use to me, since it's filled with lines and lines of code that are completely encrypted in notepad.
After running CCleaner to clean out my registry and hard drive, followed by over two hours of sytematically uninstalling programs, disabling startup items, and then finally moving on to msconfig items under the services tab, I was able to determine that "Windows Event Log" is what causes this to pop open with each new startup. (I assume everyone has it enabled under msconfig > services.)
Would anyone know why it is doing this? If I can just disable it and forget about it I will, but based on what I'm reading here, it appears to be an essential process for updating Windows: Windows Event Log - Process and Service wiki
Plus I would like to know if this is an indicator of a more serious problem. (A Malwarebytes scan did come back clean by the way.)
