hi, have the same virus,tried everything,and then i went to add and remove programs and found a program i did not install, it is called
"180 search assistant",removed it and it was a pain to remove because after i hit remove a notice came up that said will not remove till you restart,at this point puter was somewaht frozen but i was ab;e to hit restart,it was then that the program began to remove,during the
removal it kept asking if i wanted to keep it,it did this several times but
i kept hitting uninstall,it finally got removed,when i rebooted the virus did not come back up. ggods luck helen
