When i started Windows this morning I've got a pop-up message titled "Windows security alert" with the following content:
"Windows has detected an Internet attack attempt...Somebody's trying to infect your PC with spyware or harmful viruses.Run full system scan now to protect your PC from Internet attacks,hijacking attempts and spyware!Click here to download spyware remover for total protection."
Immidiatelly after this,the IE opens with the adress of some site called <http://softwarereferral.com/jump.php?wmid=6010&mid=MjI6Ojg5&lid=2>.
There is a red cross kind of icon in my system tray and after every minute a trigger pops up a message window on my screen asking me to go to some other website like <http://www.udefender.com/freeware/3/?wmid=6010&mid=MjI6OjEzMzk=&lndid=15&p=1>
Pleas tell me if you know what kind of virus is this and how can i get rid of it. I need help immediately.
I am really very annoyed from all these pop ups coming up and not letting me do my work.
Please help
