ok,
i had this exact virus yesterday.
well, make sure the virus program (security suite) is open in a window.
press ctrl+alt+del
keep pressing it until it is open long enough to go to applications.
right click security suite and go to "go to process"
try and remember what the process is called, and if you can, end the process.
once you do that, security suite is temporarily disabled.
now go to c:\documents and settings\[your username]\Application Data\
remember, to see the folder you need to be able to see hidden folders.
to do this go to tools, folder options, "view" tab, and check "show hidden folders.
in application data, find a folder that has a name made of a bunch of random numbers and letters.
this is where the virus is booted from.
delete the folder and empty the recycle bin.
if you do have a registry cleaner,use it after the virus has been deleted.
now the virus is deleted, you need to clear up its damage.
reinstall all internet browsers that you use.
well there you go, ^^
if you have any problems in the future, e-mail me @ olie777@live.co.uk.
