Help, Virus attack

[vonny_60]

Help I have a very bad virus, masquerading as some sort of security shield, its telling me I have all sorts of trojans and worms and that my credit details are in danger of being infiltrated, I cant do anything as this virus pops windows up all over the place, nothing will open on my computer now, does anybody know any tricks for me to get rid of this thing??? PLEASEEEEE
