I ran a full scan of my new computer. Everything looked pretty good except for the following message: C:\WINDOWS\Downloaded Program Files\unagiuninst.exe >> NSIS - bad archive If I open that folder there's nothing in there (I have "show hidden/system files" turned on). If I do a Web search for unagiuninst.exe I get a few hits indicating it might be a trojan, but nothing really definitive. I don't know how I could have gotten a trojan, this is a brand new computer (an HP netbook), I haven't done anything with it yet other than install FireFox. I haven't visited any questionable websites (Yahoo and Amazon are the only ones I went to thus far), I haven't even checked e-mail with it. Is this a false positive? Why can't I see this file in the Downloaded Program Files folder?
