First of all please disable the Spybot TeaTimer;
To do this can you start Spybot and go to the Mode button and select Advanced. Go to Tools > Resident and uncheck the box next to Tea-Timer.
Reboot.
Next go back to the ESET Scanner, run the scan again and have it FIX or REMOVE everything found.
Reboot.
Then run a NEW full system scan with HiJackThis.
Place checkmarks next to the following entries if they still remain;
O2 - BHO: (no name) - {FDD3B846-8D59-4ffb-8758-209B6AD74ACC} - (no file)
O3 - Toolbar: (no name) - {BA52B914-B692-46c4-B683-905236F6F655} - (no file)
O3 - Toolbar: (no name) - {4982D40A-C53B-4615-B15B-B5B5E98D167C} - (no file)
O4 - Startup: PowerReg Scheduler V3.exe
Once you have placed the checkmarks then click the Fix Checked button. Exit HJT and reboot.
You also need to do a search for that PowerReg program, it is most definitely malware. It would most likely be located in
UserProfile (this would be you so substitute your name)\Start Menu\Programs\Startup
If you find it, delete it.
Run a new HJT scan after doing all the above, INCLUDING the fixes with the ESET scanner and post those logs here.
