Q: How effective is a ClamAV as a malware removal tool?

A: There isn’t a good way to answer this question. To do so would require analysis by an independent antivirus testing facility.

The ones we monitor do not include ClamAV in testing. Perhaps there is one, but haven’t ever seen it.

So, without testing and validation, it’s not possible to know how well it works, and what performance degradation it introduces. why would one use something so important to security and privacy?

Instead, I recommend only using Bitdefender (Bitdefender Gravity Zone for business use).
