Your Startup file looks good.

Normally, I would not recommend this since ESET enjoys a good reputation.

For the purposes of trying to isolate the problem, could you:
1. 100% uninstall ESET
2. install MSE (Microsoft Security Essentials).Link in my sig.

Reboot.

Problem gone?

I'd say to uninstall it if possible.

If not, then you could try deleting.
Sure hope we don't have to go the remove here, remove there, clean registry, use Autoruns to find any references, etc.

Excellent.
I've also asked for help on this.
Let's see in all of our efforts, have you run SFC /SCANNOW to make sure that the system files are in order?

I think karl has you on the right track - I've never been a fan of AVG, and now we see why.

Only one other thing I can suggest, and I'm not sure this is even an issue, but easy to check:

Are there any unknown User Accounts shown under Parental Controls?

I saw this installed on the sly from an NVidia update recently, so I mention it only to check that AVG hasn't resorted to this same "trick", which might explain the issues with incomplete uninstallation.

Here is the thread showing how a hidden user account can slip under the radar in Parental Controls:

Unknown User Account

YEAH....I have that UpdatusUser with password protected.

Thats related to NVidia, and probably not AVG.....so I don't think thats the issue. So there aren't any other unknown User Accounts?
