"Can a virus get through my firewall?"

Yes. A firewall only protects unauthorized access through a network while allowing authorized access (see further description below). If you visit a page encrypted with a virus or other malware, it won't stop you. Always have a virus/malware scanner active and up-to-date. If you're running a scan, disconnect the machine from the internet (to keep more "nasties" from getting into your machine).

Don't get too paranoid about sites like that. I hit a site just like that and it brought up a wonderful interface that looked just like Windows explorer and showed me which Windows files were supposedly affected. The problem was, I was on my iPad. The site is just a scam to get you to buy their AV program.

By default no website has the capability to access your computers files so cannot possibly perform a virus scan. Before this can occur a program component must be downloaded that has this capability. No legitimate website is going to do this without first asking your permission. Any website that behaves otherwise has lost all credibility. Also, a scan that has a reasonable chance of finding a virus is likely to to take a substantial period of time.

So we can conclude that any website that unilaterally announces that it has detected a virus is at the very least highly suspicious. In almost every case it is a scam. In many cases the website is spreading malware while claiming to offer you protection from it.

So beware.
