the message ‘you are infected with unknown trojan’ is usually displayed by fake anti spywares. i bet you are infected with some rogue security tool that keeps offering you great computer protection after you pay. use legal anti spyware to remove that thing. i suggest spy sweeper: http://www.2-spyware.com/review-spy-sweeper.html

it makes your computer act strange when running. Some issues are change in time, mouse freezing, and keyboard disabled. Do not do anything else when it is running
Phony alerts or "balloon" pop-ups from the tray (by the clock) about a trojan, virus or spyware infection and the attempt to sell you some useless software to "fix" the problem usually indicates that your computer has a Smitfraud infection. DO NOT BUY THE PRODUCT THEY TRY TO SELL YOU! IT IS SCAM.
Sounds like your computer may have a variant of this ubiquitous Smitfraud infection. Almost all "general purpose","all-in one" spyware and virus removal programs such as AVG, Norton, or Spybot S & D cannot remove it compleatly.
Free specialised Smitfraud removal tool is here (SmitfraudFix)
http://siri.urz.free.fr/Fix/SmitfraudFix_En.php
After running SmitfraudFix, to clean-up any remaining infection traces, scan for trojans, adware, cookies, and spyware and remove (free online scan, no downloaded program) with Ewido Online Scanner ( now known as AVG Anti-Spyware). This is NOT the same as AVG Anti-Virus. Press "Scan your computer now online and clean it for free!" on the left.

Good luck.
use system restore what it does is resets your computer to before you had the virus. Be prepared to lose documents you created in between.
got to
start> run> type "MSCONFIG"> click ok> press launch system restore> then select the button that says set to earlier time or something like that> set it to the time before you found the virus> click next> and your virus should be removed.
you will have to reinstall anything you installed or any documents you might have to redo.
hope it works
You need a decent virus checker like AVG and a decent spychecker run them both
