Use anti-virus software and keep it up-to-date
If you haven't installed anti-virus software on your computer, do it now. Anti-virus software can detect many — but not all — forms of malicious software before they have a chance to affect your computer. When you purchase anti-virus software, look for one that includes anti-spyware. Most anti-virus software can automatically download updates for you. Check to make sure your software is downloading updates correctly.
Keep all your software up-to-date
You can prevent many problems by regularly checking for and installing updates for your programs, including your operating system, browser, messaging software, and other software. Many programs include a feature that automatically checks for updates. Be wary of clicking links in emails claiming to have updates for your software; it is safer to type the address of the web site into your browser’s Address bar to visit the site directly.
