The only two I know of is Malwarebytes and Kaspersky.
The former installs with root privileges, runs on boot and cannot be ever closed, despite the fact that it is only an on-demand scanner. I've written to them to request an explanation, and did not get any response.
Kaspersky has had a fair share of rumors against it, and I am not in a position to evaluate if they are trustworthy.

Because they try to up-sell you their paid option, which scans automatically for you, with a 30-day trial.
