Use Anti-Virus Software

Anti-virus software protects your computer from cyber viruses that can spread to your computer through email, instant messages, and file-sharing programs. These viruses can delete files or cause your computer’s programs to work incorrectly. They can also put unwanted text, video and audio messages on your computer.

A good anti-virus program will find and delete any virus that’s on your computer. They will also repair damaged files. Once your anti-virus software is installed, make sure you keep it up to date.

Try these reliable programs:

• Norton Security Scan/GooglePack: this is a collection of free software that includes virus protection. You choose to download only the programs you want. If you’re willing to pay for more features, try Norton 360.
• Windows Live OneCare: get a free 90-day trial to see if you like it.

Using your anti-virus software is easy:

1. Open your anti-virus program. You can find this on your tool bar, desktop, in your start menu, or by searching your hard drive.
2. Follow the instructions step-by-step.

If your anti-virus program cannot repair an infected file, it may take one of the following actions:

• Quarantine the file and stop it from being used, or
• Try to delete the file

If an infected file cannot be deleted, your virus-protection program will tell you what steps to take next.

Other ways to protect your computer from viruses:

1. Install the latest security patches offered by your operating system (like Windows). 
2. Don't Open Junk Mail.
3. Install a Firewall.
4. Only Download from Trusted Sources.

The most common types of viruses are:

Worms: A worm is a program sent by email, that copies itself and spreads as quickly as possible. Worms can steal information from your computer and send it back to an online criminal.

Trojans: A trojan is a downloadable program that looks like it’s good for your computer (like free virus protection) but is actually designed to damage your computer and steal your information.
