Firewalls: If you haven't already, going into your computer's settings and configuring it to be moderate to strict will help you prevent infections. If viruses are already on your machine, they can usually prevent them from communicating with anyone on the internet.
This will prevent the virus from spying on you or exfiltration data off your device. Most operating systems have a default firewall, but they aren't set to the most secure settings by default.
Factory Reset: If you're desperate to get rid of a virus and antivirus doesn't seem to help, you can do what's called a factory reset.

Your individual solution will depend on factors like the size of your business, industry, organization type, and long-term business goals. The easiest way to illustrate multilayered computer virus protection, is by imagining each individual layer of cybersecurity as a slice of swiss cheese. Each slice has a few holes in it, and as you stack slices on top of one another, you cover up the holes. Download the Essential Business Guide to Cybersecurity.
