Answer 2

You can download trial version of Anti-virus (works for a limited time) off the vendor web site. You can download a paid version (after paying) from the vendor/online store, but NEVER download anything from unauthorized sites. It could be pirated or infected with virus.

Answer 3

All of these are ones that I personally use and all are free.After you install any of them,make sure you update them to get the full affect.

Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there's no harm giving it a try to see if something has invaded your computer.

Answer 4

I would not trust downloading from those random unknown sites. Try AOL, they have a free Safety and Security Program. It includes virus protection, a firewall, phishing protection and spyware protection. Hope this helps! :)

Answer 5

Yes, but only some are safe.

You should look for AVG FREE (anti-virus)
or
if you want a firewall ZONE ALARM (zonelabs.com)

You should avoid downloading anything when it says you need this now or danger or attention (yield sign) be careful h
