Well if the are quaranteened, its ok, but personaly I deliet everything thats quaranteened, if you really did find trojans, it not take care of all of them, one run never does.
Run
http://www.malwarebytes.org/ and see what that pulls up, and when done?
deliet everything it shows, the next night also before you go to bed, then when you wake up,you can look at the results and see if any are comming back or hard to get rid of. let me know if issue of comming back.
Thats why lots of people don't try to help other's online,
main reasons being: they want a instant fix. second if computer messes up we are to blame.
We can fix this!, just breath, and continue at slow pace to not get mad, COOL?
Only reason why I asked for the Exact message/Code was, it's a clue, it not a problem that you don't see a code, I was just wanting what it gave you, It does take time invested and paitence to get the results you are wanting, it took this long to get you to give me the message you are seeing Why it won't download, now I have something to work with
Many People get upset, this is why some just take their computers to the geek and pay all that $$$.
it takes times to fix someone elses computer when your not in front of it Their are many ways to download and get sp2 to your computer.
Seems we might need to find what is missing/needed to allow the download, wich aint impossible, as before we can fix at your pace, I will post her tomorrow after doing a bit or trouble shooting your responce.
Keep your fingers crossed, I might just luck out and get it fixed on next post.
