The problem with the Say no to drugs virus is that most virus scanner still do not detect it. Extensive information about this virus is available on the Precise Security website. If you suspect that your computer is infected with this virus you need to download the (free) Ewido Micro Scanner and perform a scan of your system. Remove the entries found and remove the entries of the virus as an autostart entry (autoruns comes in handy) and kill the tasks associated with the virus as well.

I was not able to find out if other products like Spyware Terminator or the various anti-virus applications like Antivir would be able to find and remove the Say no to Drugs virus. I was not infected with it but I guess they should be able to if you consider the fact that the removal procedure at the Precise Security website was posted in January.
