No matter how sophisticated computers may be, they are vulnerable to threats. Malware is a general term to describe malicious software. Among the many forms it can take is that of a virus, which is designed to spread to different devices—usually with the purpose of gaining control of your accounts or stealing your data. Depending on the nature and extent of the "infection," virus removal can be difficult, so it's crucial to catch the warning signs ASAP. To better understand how they work and how to protect your computer from them, take note of the following.

An Introduction to Computer Viruses

Basics

A computer virus is a hostile program or code snippet that removes, adds to, or alters existing computer code for its own purposes. It is also designed to replicate itself once it latches onto a compatible "host." This host can be a particular file or another type of software.

Because of its self-reproducing nature, any virus removal attempts that are not thorough will leave behind enough corrupted code to allow it to continue to scatter and infect.

Protection

Setting up fortifications is much easier than virus removal. If your computer has Windows®, use "Microsoft® Defender." Formerly known as "Windows Defender," this is an antivirus program that's already installed on the operating system. It offers real-time protection, which means it runs continuously in the background to scan for risks.

However, this isn't enough. You should also invest in antivirus software designed to look above and beyond the usual suspects, such as that offered by Webroot. 

In addition to antivirus, which searches internally for threats, install firewall software too, which monitors network traffic and throws up a barrier against malicious programs.

You should also avoid clicking on pop-ups and links in emails from people you do not know, both of which may try to lure you to unusual websites or to download dangerous programs.

Keeping your computer up-to-date will also help, since these are often meant to provide “patches” to holes found in code that might, otherwise, let viruses through.

Signs

The most apparent indications your computer has a virus are strange pop-ups, slow performance, crashes, and unfamiliar programs. However, viruses aren't always so blatant. 

Sometimes, it's a small change like a different homepage on your browser or new folders on your hard drives. If you notice anything out of the ordinary, run your antivirus program or take your computer to a repair specialist.
