Fatal System Error (associated w/ csrss.exe) PLEASE HELP!!

Firstly, I would like to say (in advance) that I am TRULY APPRECIATIVE of any/all help that the fine folks at MajorGeeks will give me regarding my problem(s).

Ok,....I like to think of myself as an "above-average" person when it comes to the health & welfare of computers. In most cases, I wouldn't trade my computers that are 5 or 6 years old for some of my friends that are only 6 MONTHS old. But I guess that's irrelevant.

I'VE FINALLY BEEN HIT!!.....AND HIT GOOD!! Sometime over the last week or so, I managed to get "virused" and "malwared" REALLY BAD!! I've isolated and/or deleted some, but apparently, the really bad ones remain. In researching, I found that a particular TROJAN likes to mask itself as CSRSS.EXE. Well,....I took it upon myself to delete it, and now I get the 0xc0000005 Fatal System Error message. I also researched and found that that particular F.S.E. message is associated with CSRSS.EXE.

So,....in short, I can't boot in normal mode. I can't boot in safe mode. I can't boot in safe mode with command prompt. It's also worth noting that one of the GAZILLION viruses/malwares/adwares that I've picked up over the last week, won't allow me to use System Restore neither. I also do not know where my system restore CD is neither.

PLEASE HELP!! I REALLY NEED IT. Thank you again in advance.
