wow, you have just got a main virus, which ediot gave you that, i want it, anyway, chek this out:
I wrote somet out:
Ok, on your Kboard, Press (CTRL+ALT+DELETE), After this you should have Task Man... On, Simply click Processors and End process of anything that you no.
Anyway, after this, download or use your Spyware program to scan your pc.
Now type Spyware Doctar in, make sure spelled correct, aftern that download/run/install/open program, now scan your pc, then Add/Remove Programs, after this, delelte all the stuff you dont need, once this is done follow the next.
Click Start then click Run, once done this type CMD in, once this has done, type IPCONFIG /RENEW
Leave it to refresh your internet connection then it will open all connection and should Prompt you with your firewall setting (It might not) Once its done, make sure all firewalls on your router/Modem/cable box is On.
Goodluck, hope this helped and removed shit from your Pc.
