An antivirus is software that protects against computer viruses, a type of malware that self-replicates by inserting its code into other software programs. The best antivirus programs scan files to protect your computer and devices from such threats, while keeping resource consumption to a minimum.

What is the Difference Between Malware and a Virus?

Malware is a term for any type of malicious software, regardless of how it works, its intent or how it’s distributed. A virus is a specific type of malware that self-replicates by inserting its code into other programs.

Should I go for free or paid antivirus?

Usually free antivirus software offers baseline malware protection that may not be sufficient to combat the ever-evolving threat landscape, particularly when it comes to the wide variety of zero-day threats and/or digital threats that go beyond just antivirus. Rest assured that with our free 30-day trial you’ll get all the features of our flagship McAfee® Total Protection suite, including antivirus, web protection, password manager, file encryption and more. Take advantage of our free trial and gain greater peace of mind every time you use your devices.

How to avoid a fake antivirus software?

Fake antivirus software is one of the most persistent threats on the internet today. Masquerading as legitimate antivirus software, fake antivirus software is in fact a malicious program that extorts money from you to “fix” your computer. And often, this new “antivirus” program disables legitimate security software that you already have, exposing you to real threats. These rogue programs try to hook you while you’re browsing the web by displaying a popup window that warns you that your computer may be infected, and that you need to download (fake) security software to fix the problem. This type of software is often referred to as “scareware” since the pop-ups use messages like “You have a virus,” as a way to get you to click. Most of us are eager to get rid of any potential problems as quickly as possible, which in turn has made the bad guys who make fake antivirus software so successful. Once you agree to the purchase, the cybercriminals end up with your credit card details and other personal information, and you get nothing but malware in return.
