My anti-virus won't run

[Dan Kira]

When i tried opening a site an advertisement popped in. It was asking me to download it because my computer has a lot of virus. So I tried to download it. When I opened the file nothing seem to happen but my anti-virus won't run. Please tell me what should i do. Thank you!
