VirusTotal is used for its definitions, but it also checks your software for CVE warnings. It runs in basic mode for free so lacks some disinfection ability. Something similar but perhaps more useful is the MetaDefender tool from OPSWAT. No sign of the next version yet and I won’t hold my breath waiting. Herdprotect is no longer available on the home page but is still working so you could swap to a link to MajorGeeks.
