HELP! I had a Flashback Trojan/Malware on my Mac, I deleted it in trash, and now my Mac won't start.

Question

At first my Mac Finder showed n81, n82, etc when you right-click it, instead of the commands " open new finder window", "hide" etc. I also noticed that sometimes, when I would go to sites such as facebook, it would redirect to a different site and I'd have to type in the address again to get to the site. Nothing else was wrong with it. Safari was not shutting down. It wasn't slow.
I did some research and found that I probably have the Flashback Trojan/Malware virus (whatever that is?) And so I followed what some people did (which got their mac fixed) .. I downloaded clamvax and tinkertool to find the malware (hidden files) and I deleted it in trash.. my computer seemed fine but when I restarted it, it wont turn on anymore.. the screen remains blue, the mouse could still be moved, but it stays that way..
did I lose all my files? am I being hacked as we speak? Is this virus very dangerous?! I am very paranoid and know nothing about this kind of stuff so please help!
BTW, the malware was from the game Farm Frenzy.. I have no idea how I got this... I never play online games.

@Thomas, Thanks for jumping in. I had to take my wife to a Doctor appointment and things went down hill from there.
I note that you are using Mac OS X 10.5.x.  It's important to understand that the Java vulnerabilities that allowed this malware to get established on your machine cannot be fixed in 10.5.x.  You would need to upgrade to at least 10.6 (Snow Leopard) to be able to get a version of Java with those vulnerabilities fixed.  (Correct me if I'm wrong there, Al!)
That's 100% correct. Natalia has the distinction of being the first OS X 10.5 user confirmed to be infected by Flashback as far as I can tell. That operating system is becoming increasingly dangerous as the days go by. The OS has not been updated since Aug 2009 and the last Security and Java updates were in June 2011. There is no XProtect system and more and more third party's have dropped support in updating their Applications.

I actually ran disk utility, and it said that the Macintosh HD is fine... I also tried safe mode/safe boot and did the FSCK command.. even that said that my laptop was fine? but somehow it still stays blue when I start up!
And I think it probably is fine, except that something is hanging during the initial loading process. Could be most anything.
As for my files, I appreciate your advice but I am scared I might do something wrong and mess my laptop up even more!
There is almost no chance of that and at this point it should be obvious to you that if the files on your laptop are that important, you should already have a backup.
I will take it to Apple and hopefully they can help me... because it seems that my files aren't wiped out... yet... It still displayed that I had my files in there..
One word of caution, then. I have been told that Apple has instructed their support folks not to attempt to clean up a malware infection. If I were you I wouldn't bring it up unless you have to.
By the way, while the disk was running, it was making very loud noises.. humming/grinding/etc... what could this mean?
Only one thing in my experience, you're hard drive is toast. All the more reason to try and get all the data you can off it immediately.
The only way to test it is to do a surface scan which Disk Utility cannot do. You would need a third party utility to do that. If it tells you there are bad sectors, that is 100% proof that it's going bad, as modern hard drives repair themselves of bad sectors until they run out of reserves to substitute.
