No matter what I have DONE(Norton virus scan,Spyware Doctor,Spybot search and DESTROY,cwshredder)this thing comes back.
It is a popup ad in mutliple variations from www.vv3.s13.tempx.cc
It says your PC is infected in an attempt for you to go to their site and buy software.
At times it takes over the brouser and I have to shut down.
After running virus scan on Norton I get a popup window stating that 4 viruses REMAIN and my pc is still infected.               :'(Help.michaelj1006.......You really should have posted this in the spyware and viruses section ....but ......what operating system are you using .........?
When Norton detects the 4 viruses........it must say something like Deletion failed ......but it should also name them and tell you where they are residing ......
Can you give us this info .......?
Also try this.......shut down your internet connection , reboot into safe mode ........then while in SAFE mode run Norton again and see if you can delete these pests.

Let us know

dl65  Sounds like you have a highjacker, download adware away and run scan and remove the highjacker program
