How the virus goes from a site to the PC? – Totty 2 hours ago
@Totty - Your PC has to download the site's files (HTML, JPG, SWF, etc.) to a local location (either on the local HDD, or in RAM) in order to view it. Then, the browser will process the code necessary to render the site for your viewing - which may include exploit code. – Iszi 30 mins ago
But in order to activate the virus, the browser must have vulnerabilities in opening files as is the only thing that will open those local files. – Totty 22 mins ago
