I'm really not sure what happened to those logs, but given their incomplete state, there's not much of anything to work with in them.
Let's se if we can get things back to at least somewhere near normal:
1. Download and run IEFix. Reboot when finished.
2. Download and run CCleaner. Again, reboot when finished.
3. Do another run of ewido, MS Antispyware, etc.
4. Post another log; hopefully we'll see some improvement.
