Why Is Antivirus Software Important?

If you purchased a new desktop, laptop, or smartphone, you probably assume it will operate at lightning-fast speed for at least a few years, right? Wrong.

Without antivirus protection, your shiny new device can fall prey to one of the many tools at cybercriminals’ disposal. Your passwords can be lifted, your bank account emptied, and your identity stolen.

Here’s why antivirus software is important and which ones you should consider installing:

Comprehensive Threat Protection

Modern criminals have an arsenal of hacking weapons to take down your system. These include:

  • Traditional viruses, technically known as “macro viruses,” propagate on host machines. They are often spread through corrupted email attachments and target commonly used programs such as the Microsoft Office Suite.
  • Malware is a broad category of digital threats that includes trojans and spyware.
  • Boot sector viruses target the firmware that plays a critical role in starting your computer. It may leave you with no way to get into your machine.
  • Ransomware makes your system unusable until you pay a ransom to the criminals behind the scam.
  • Spyware scares some privacy experts the most, imagining a criminal watching you through your webcam and then using the images as blackmail.

The good news is that many antivirus programs will provide protection against a lot of these. The bad news is that some others only scan for old-fashioned macro viruses.

It Increases Your Computer’s Lifetime, Saves You Money

If your computer has become an expensive doorstop, you have to remember that prevention is better than cure.

You can attempt to repair a broken operating system, but it’s far easier to quarantine viruses before they destroy the machine. Many viruses can render their host systems basically unusable while others will prevent the user from installing any new programs—including antivirus programs intended to remove them. Reinstalling the operating system can mean reverting to a restore point and losing important files and data. 

Finally, not having antivirus protection could kill your professional reputation. Plenty of viruses act as spam-bots, hijacking your desktop email program and sending embarrassing unsolicited mail to your contacts. Viruses can also hide behind your computer’s IP address to make illegal downloads, potentially incriminating you in unlawful activity.
