virus stops computer from opening programs including Avast

Hi,

I downloaded a virus pretending to be a JAVA update on icefilms.net. As i let the program in, I guess Avast did not see it as a malicious… Everything froze and i restarted the computer. Now, my laptop boots and gets to the desktop but I cannot open any programs. No internet explorer, No Avast! Only one program opens pretending to be Windows Defender and it asks for 60$ to download the windows anti-virus (which does not exist). How can I start avast? Can Avast be started from a boot disk or usb key to perform a scan and remove the virus?

BTW. I run Windows Vista.

thanks

Hi three programmes to run - two to kill and one to sweep up the residue and do any repairs

[*]Quit all running programs
[*]For Vista/Seven, right click → run as administrator, for XP simply run RogueKiller.exe
