**Be sure to install anti-virus software on your computer to protect your information, money and privacy. Such software detects viruses and cleans your computer so that harmful viruses do not spread. Set up your anti-virus to run frequent scans and update the software as soon as it is required. Ensure you have real-time scanning of every email and every file you download.**
Malware
Malicious software (malware), spyware, worms and Trojans are the same class of destructive viruses; just with different names. Nobody wants a computer virus. They can steal your personal information, take over your PC and use your computer to attack other people's computers. Your PC can become infected through email attachments, downloading infected content or visiting harmful websites.
Spyware
Spyware is exactly what it sounds like – tracking software that is downloaded to your computer (without your knowledge) when you visit certain Internet sites. Secretly, it gathers information about you and your browsing habits. This information can be trivial or it can include passwords and personal data that you wouldn't want criminals to get their hands on. It can also interfere with user controls and disable legitimate anti-virus programs.
The best way to protect your computer against spyware is smart browsing. Stay away from sites that look unsafe and avoid streaming or downloading content from untrustworthy sources. Many anti-virus products offer targeted spyware solutions that inspect your operating system, installed programs, downloads and files.
Scareware
One of the most common viruses to watch out for is known as scareware. These scams pop-up on your screen and display alarmist warnings, telling you a virus has invaded your computer. Scareware prompts you to download (and often pay for) fake anti-virus software to remove the non-existent viruses. Scareware is a scam that tries to trick you into paying money in exchange for nothing.
You can protect against scareware by keeping your anti-virus software up-to-date and by being judicious about what you choose to download to your computer. You should also familiarize yourself with the interface of your legitimate anti-virus program, so you won't be fooled if one of these pop-ups appears.
