How to boost your malware defense and protect your PC

Build up your malware defenses
Install antivirus and antispyware programs from a trusted source
Update software regularly
Use strong passwords and keep them secret
Never turn off your firewall
Use flash drives cautiously

Don't be tricked into downloading malware
Instead, follow this advice:
•Be very cautious about opening attachments or clicking links in email or IM, or in posts on social networks (like Facebook)—even if you know the sender. Call to ask if a friend sent it; if not, delete it or close the IM window.
•Avoid clicking Agree, OK, or I accept in banner ads, in unexpected pop-up windows or warnings, on websites that may not seem legitimate, or in offers to remove spyware or viruses.
◦Instead, press CTRL + F4 on your keyboard.
◦If that doesn’t close the window, press ALT + F4 on your keyboard to close the browser. If asked, close all tabs and don’t save any tabs for the next time you start the browser.
•Only download software from websites you trust. Be cautious of "free" offers of music, games, videos, and the like. They are notorious for including malware in the download.
