Sounds more and more like a malware problem. I'd like to do a couple things really quickly before moving on.

1. Can you please open AVG and tell me the last time the definitions updated, and the date of the last scan.
2. Also, please look in the AVG history, in the virus vault, and delete anything that might be in there.
3. Please look in your Start/Programs and verify Malwarebytes does show as an installed program (even if it won't run.)

Don't try to run anything just yet. Just let me know what you find.

Edit: I'm glad you got SAS to load and update. It's a long scan but remove anything it finds. Then reboot your system and see if you are able to login to WLM. I'd also suggest verifying that AVG has been updating and running.
