Your logs look pretty good.
You should run CCleaner to empty all temp files. If you don't have it download it and install. Open the program. When it opens it will open on the Windows Tab with checkmarks all ready in place. Don't change anything. Click the Analyze button. It will scan the computer for items which can be removed. When it completes it will show items marked for removal. Click the Run Cleaner button. Close the program when it is finished.
You need to uninstall combofix now.
Click START then RUN
Now type Combofix /u in the runbox and click OK. Note the space between the X and the U, it needs to be there.
When shown the disclaimer, Select "2"

Delete SDFix from your desktop, also delete this folder C:\SDFix

Empty the Quarantine files from MBA-M

You also need to set a new, clean restore point.
Right Click My Computer, Choose Properties.
Then click the System Restore Tab.
When that opens put a check mark in Turn Off System Restore.
You will get a warning that you are turning it off, click OK
System Restore will now turn off.
Wait until it is off.
Then go back in and Remove that Check mark. System Restore will turn back on.
Is the computer running ok now?
Please post back with that answer. I will be away for several days but crunchie is checking my threads. If you have any questions he will try to answer them.
