If you have ever owned or used a computer, you’ve probably heard the words “antivirus software”. In fact, you might even have one already installed on your computer, protecting your files and identity without your knowledge. But besides being something that you know without a doubt that you need, what really is “antivirus software”? First, you need to understand what a virus is. “Computer virus” is a very broad term for any program designed to multiply between computers and interfere with their operation. Antivirus programs protect computers against viruses by identifying their suspicious behavior and placing them in quarantine or deleting them. Today, most antivirus programs protect against all types of threats, from viruses, trojans, and worms, to adware, spyware and phishing attacks.

What to Look for in Antivirus Software?

Every computer today needs antivirus software, but the possibilities are endless and often confusing. Here are 5 features to look for before you decide which one is best.

  1. Scanning and cleaning
  2. Signature detection
  3. Behavioral detection
  4. Backup
  5. Two-way firewall

There are many more features out there, such as anti-spyware, child-protection and filtering, and more. Read as many reviews as possible and look for something that has all of the above features and additional features specific to your needs.

Why Should You Pay for an Antivirus Software?

Having a good antivirus program running on all of your devices is important to protect your files and personal information. Although there are numerous free products out there, it’s important to choose a security suite that answers your needs and provides you with the protection you require.
While some companies do provide anti-spyware or anti-adware products for free, good antivirus protection will usually require you purchase a security package.

What Kind of Damage Can a Virus Cause Your PC?

Once a virus installs itself on your computer, its main objective is usually to spread to other programs and files and any computers connected to the same network. What it does after that varies, depending on the code, but usually significant damage is involved. Some viruses corrupt or delete data from your computer, often deleting everything from your hard disk, while others attack servers with the purpose of bringing them down completely.

Conclusion

Having a strong security suite installed on your devices is important if you want to protect your files and personal information. All-inclusive security suites these days contain features that provide complete protection on all devices, from mobile to PC, and include email protection, safe browsing, and protection from harmful links on your Facebook or Twitter timeline.
