How can I kill this computer virus, and what is it?

I got this virus on my computer that changed my desktop background to Warning! Spyware detected on your computer! Install an antivirus or spyware remover to clean your computer. And it changed my screensaver to a bunch of cocaroaches.



I also keep on getting random popups every now and then.How can I kill this computer virus, and what is it?

MESSENGER SPAM



XP Home:



this set up is for Internet Explorer alone



do you get pop ups claiming that your computer is at risk?



those are called ';Messenger Spam'; !



to stop messenger spam:



open start page



open administrative tools



open services



these services are in alphabetical order



you need to close two:

a] Alerter

b] Messenger

NOT related to MSN messenger or any other instant messenger



right click each service



click properties



from drop down menu,select disable



another method to deal with those that get through is to copy the pop up address at the top of the pop up or pop under [ starts up AFTER you close a window ]



open internet options [ start--control panel--internet options ]



open content tab



open settings



open enable



enter address



click never



close



open Advanced tab



check to see if pop up blocker is checked



close

Zonealarm is a good free firewall product.



You have something called 'smitfraud'.

There are programs specifically to kill that if you dont want to do all the above programs.
To get rid of it, download the following:

Avira: http://www.free-av.com/ (if you don't have anti-virus, or if you have Norton or AVG replace it with this)

Spyware Terminator (turn off web security guard): http://www.spywareterminator.com/

Spybot: http://www.safer-networking.org/ (use immunise feature)

Superantispyware: http://www.superantispyware.com/

Comodo: http://comodofirewall.notlong.com/ (turn off defense+ to see fewer alerts)



Update all and scan your computer, removing or quarantining what is found.



In future, do not click on adverts, and do not download from dodgy websites promising free stuff that you have to pay for elsewhere.



Use firefox: http://www.mozilla.com/ and the AdBlock extension (http://tinyurl.com/2cd87q ) and whatever other useful extensions like Download Statusbar you want.
Get an ';antivirus'; program. There are free ones, like here http://www.free-av.com/ - search google.



Also get an ';anti-spyware'; program, like lavasoft from http://lavasoft.com/ (also free)
