FAQS

Yes. Plus, viruses are far from the only type of malware you might encounter. Malware has many faces and gets spread in different ways, whether it’s blackmailing with ransomware, spyware monitoring everything you do, or a Trojan that’s hidden in your PC software. There are other kinds of dangers too, such as unsecured public Wi-Fi hotspots, which are often used to launch cyberattacks. Also, when you go online, phishing websites can target your online account login details.

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. There are many ways cybercriminals distribute malware and viruses, but the most common are malicious emails and websites.

Fake antivirus software is one of the most persistent threats on the internet today. Masquerading as legitimate antivirus software, these malicious programs extort money from you to “fix” your computer. This new “antivirus” program even disables legitimate security software that you already have, leaving you exposed to real threats. These rogue programs catch unsuspecting users by displaying a browser popup that warns you that your computer may be infected, and that you need to download a (fake) security software to fix the problem.

Yes. You can easily get free antivirus software for your laptop or PC. The key thing is to choose an app from a reputable brand, especially one with award-winning credentials that you can really trust. At Avira, we offer a reliable, free Windows antivirus of our own that gives you real-time protection against various different kinds of cyberthreats.

Windows offers basic antivirus protection with the pre-installed Windows Defender app. Unlike Avira Free Antivirus for Windows, it does not have additional cyber protection levels and online privacy features. These include a free VPN, a password manager, a browser safety extension with phishing protection, and a software updater that updates third-party PC programs to help prevent security vulnerabilities. That’s why we recommend using our free antivirus protection app, Avira Free Antivirus, on your Windows computer to boost your online security.

The majority of common problems, such as silent trackers, unwanted apps, and junk files, can be resolved by it. But expecting any tool to catch everything is unrealistic. Stay alert yourself. Skip shady sites, avoid free downloads, and let your habits work with the software, not against it.
