Virus Threathens My Job

Good day My fellow Naira Landers

I do not know where to post this, but i know i need Solution

I work with an American oil servicing firm in Nigeria
Just like any other Corporate Organization Browsing is an Offense
Except for official Purpose or outside work hours

when i get to office i usually sign in my messanger to see upcoming mails
One of my friends on my messanger list said i should Click a link to see his Picture

That was the Genesis of the problem
Unknown to me it was a Virus
This are now the effects
        It has made the Site my permanent home page
   It automatically sent the link to all the contact in my list, some of who i know will have clicked it an now be facing the same problem
   My Task manager is no longer active.
   Run is no longer available on my system.
   If i want to compose an email, once i type the email i want to send it to, and i type the subject it will just add the following for me
         "Click www,,,,,,, com to check out my pics" and send the message Automatically

From my Knowledge the Virus is a program that is runing. that is why it has disabled the task manager so that i cannot end the Program.   

Please does anyone have an idea to the solution.

What i just discovered is that the it has now spread to two system in the company
The Virus is not only threathning My computer and Network.
It is threathning My JOB

hi aribells
im familiar with this virus that comes thru your messenger
all you have to do is use your system restore, and restore your system to an earlier date , earlier to the time d virus entered.
to get to system restore function. you can go through the hel and support of your system, then click on performannce and maintenance. on the list you shuold be able to see "performing system restore.
it works like magic. it worked for me.
