Mozilla does not produce an anti-virus/anti-spyware application, nor does Mozilla produce a firewall. Firefox does not scan your system for infections and will not clean infections from your system. There are many free and paid firewall, anti-virus/anti-spyware applications available. Search with Google for '''''anti-virus''''' or '''''security suite''''' or '''''firewall''''', look for reviews and choose what best suits your needs. Firefox includes a component that helps to keep you away from '''''known''''' malware and phishing sites. *Safe Browsing component in Firefox: http://www.mozilla.com/en-US/firefox/phishing-protection/ *'''''Sample''''' warning screens: **Phishing: http://www.mozilla.com/firefox/its-a-trap.html **Malware: http://www.mozilla.com/firefox/its-an-attack.html '''If this reply solves your problem, please click "Solved It" next to this reply when <u>signed-in</u> to the forum.'''
