Never mind the title then.
Try installing and running a program called
HijackThis. Just run it in administrator mode, do a scan and save a logfile, and after paste that logfile into
this site's textbox. Press analyze and check if there's anything wrong. If you have any doubts, please, post them here.
The ESET Smart Security is an A-OK AV, in my opinion, as I also use it. There's just one problem with it, without real-time protection over all things, rootkits get in very easily (as well as with any other AV with real-time disabled) and are (almost) never spotted after they're in.
Winpatrol is a very good tool, but only if you know what you are looking for.
And if Malware bytes didn't find a rootkit, either it's very well buried (and in that case, any other anti-rootkit won't find it) or it isn't there at all.
You said you didn't find practically anything about you're problem. I did some research, as this is a rather odd thing, and found out that this, in case of not being a rootkit, it's most likely a corrupt registry.
Backup your files, boot into safe mode, and run for a last time all of your security systems, as an administrator and enable low-lever searches if that's available. Low-lever searches are needed because the rootkit (if there is one) can be running with a kernel driver and in safe mode it will be disabled (hopefully

).
If it was a rootkit and you solved it, your problems should be gone, if not, there are more drastic measures:
1 - Repair Install
Then login to your computer, take your Win7 DVD, and with it try to do a repair it with the repair install option. This may correct any problems with the Windows registry. Beware some applications and drivers may need to be reinstalled after this.
Heres a neat Guide on how to do it.
2 - Format and Reinstall Windows
This one is pretty much known by everyone that uses a computer and already has had a serious problem with it. It's the harshest approach, but most of the times, the most effective.
Due to the lack of info on that particular problem, there aren't any more options I can give you (for the time being...), as it is a very awkward problem.
P.S.: If anyone else wants to give any more inputs to help, I think they would be very welcome.
Please help. I am having the same issue. Thank you.
