FAQs

Windows 8 already has an antivirus, Windows Defender, built-in. However, it is widely accepted that Windows Defender is not the best Windows 8 antivirus out there. There’s not enough protection from Windows Defender to keep your data safe. It is highly recommended that you switch to a third-party antivirus to keep your PC secure from threats and malware.

You need a virus scanner and removal tool in order to check for viruses on Windows 8. With Avast Antivirus for Windows 8, you can automatically scan your system for viruses, and remove them. However, any virus scanner and removal tool, assuming it’s reputable, can do the job.

If you’re using Windows Defender, you don’t have to do anything: it’s automatically enabled. However, if you want to set up a third-party antivirus, like Avast Antivirus on Windows 8, then you should follow these simple steps:

1. Download the antivirus software of your choice
2. Double-click the file when it’s finished downloading
3. Run the installation wizard and follow the instructions
4. Once the installation wizard is complete, open the newly-installed app
