Ok Osaid,
We've got you started toward a clean running machine, but you may still be having difficulty, if not with Nero, then pretty soon with your machine as a whole.
I say this because the items you indicate you "removed" from your StartUp are actually malware items.
(the spelling of the items is a little different from usual, but I'm still pretty sure you got some bugs there)
Since I don't know what Anti-malware utilities you have installed and updated, I'll make a few recommendations, or you can get a general overview of what would benefit you to have on your machine, Here:

PCPitstop is my "home forum" and reliable, but you can find similar information here at TomCoyote as well.
Download, install and update Spybot Search & Destroy version 1.4 and Ad-Aware Person SE ver 1.06r1
then,
Open Spybot S&D.
At the top of the Spybot screen "click" Mode and Select Advanced Mode.
A column of items will now appear in the left side of your Spybot screen.
Select: "Ignore Products"
Now a listing of all the products that Spybot identifies will fill the white screen of Spybot
Scroll down the list.
You will notice that 3 or 4 will have a "checkmark" in the box to the left in front of the item.
Remove the "check mark"
You'll probably notice those 3 or 4 are items like New (dot) net, and SideSearch, and c-Dilla.
If you run Turbo Tax you may want to allow c-Dilla to remain checkmarked, but remove all other check marks in the Ignore Products listing.
MAKE NO OTHER CHANGES TO THE CONFIGURATION OF SPYBOT S&D
Now at the top of the Spybot screen again, Select Mode, and Select "Default Mode"
Now run your Spybot S& D scan. Allow it to remove any item it identifies in Red.
Then Run Ad-Aware Personal SE ver. 1.06r1 as FULL SCAN
Now download and install Ewido trojan scan from: http://www.ewido.net/en/download/
It's a trial version, but will continue to be an excellent tool for you after the trial period expires.
You'll just have to update it manually. Keep it. It's a great tool.
Run Ewido Scan, but don't allow it to automatically delete items it identifies.
Instead, read each identified item, and decide for yourself if you want to delete it.
Why do this manually?
Well Ewido does occasionally identify items that a user really wants to keep. Most often this occurs if the user is a "gamer" and Ewido identifies items from games.
After running Spybot, Ad-Aware, and Ewido, update and run your onboard Virus Scan.
Please post back here with results.
In the event that you have a "persistant" infection, we'll look at more specific tools, and/or refer you over to the HJT Forum.
Please post results here first (but not a HJT Log, since we don't analyze HJT in this "Other Problems" forum)
Best Regards
