Okay so I am on my roommate's laptop because mine doesn't allow me to get on the internet. I did a search but I never found a direct answer. Ok, so I was trying to find a CS4 trial download (Im running Tiger and CS5 wouldn't install) and I think I probably downloaded and, yes, put in my password, and installed some trojan. The install did not fully go through so I didn't think anything of it at the time and deleted the obvious files. Now I can't get on the internet (Airport says I am connected but do not have an IP) and my spotlight stopped working: the little load icon on the left side of the search doesn't show at all and I cant press enter. I click on the desktop and then on spotlight and it says "No results found" What can I do to find the trojan? How can I remove it? Should I do a clean install? How can I save my documents/pictures/music/etc? Will the trojan contaminate my files? Ughh I feel so stupid.
