Antivirus looks for files and actions, whereas Heimdal looks at traffic. Therefore, Heimdal and Antivirus work independently but in tandem. Heimdal prevents hackers from taking data from your PC and moving it out of your network.

Heimdal works with any antivirus engine on the market. The combined protection you receive will vary between the engines used but Heimdal will always add traffic based protection against new 2nd generation attacks, where no antivirus product is able to intercept these attacks.
