i downloaded jamella off another site and it gave me trojans! Can someone please tell me how to get rid of them?? im not a computer expert so i need very detailed instructions. I appreciate any and all help

First off, AHHAHAHAHAHAAHA, sorry but I had to do that. You have it coming whenever you download random stuff without knowledge of who and where it comes from.

Solution(s):
1. Get a virus scanner, and scan/clean your hard drive.
2. Format your hard drive, and start from scratch.

OMG really??? Or do you just want me to waste my time and screw up my computer?

Its not that bad.. like he said, get a virus scanner (or use something like http://www.trojanscan.com/trojanscan/trojanscan.htm) and if that doesnt clean the viruses it may however tell you which ones are on your computer... then you can seach google or wherever for a fix specifically aimed at that trojan..
last resort backup all data (scann it and make sure that isnt infected) and reformat.
