Well, you have Viewpoint Manager, which I would get rid of. It's not necessarily malicious, but it is considered
foistware. Other than that, I'm not seeing anything malicious running on your computer. Just to be on the safe side, you might want to update your AVG and scan with it in Safe Mode.
Also, you need a firewall. You're vulnerable without a firewall, so you should look into getting either
ZoneAlarm,
Kerio Personal Firewall, or
Comodo. They're all good free firewalls. Just be sure you only have
one installed at a time! Download the firewall of your choice, disconnect from the internet, disable Windows Firewall, and install your new firewall.
Let me know how the Safe Mode scan goes.
