We have a total of 3 malware scanners on each server. We are one of the few providers that use this many malware scanners on the server.
One premium malware scanner is included for free that scans and automatically quarantines any suspicious files. We use ImunifyAV+ or ConfigServerXploit (CSX) as the premium scanner.
Another is a scanner that comes along with cPanel called ClamAV - this is the one you see in cPanel (Virus Scanner) and runs on demand.
The last one is Maldet - it does not come along with cPanel, but most hosting providers install it as it is a highly-rated free scanner. This runs once daily, and any suspicious files are quarantined.
Is it all I need to know to keep my sites secure?
Ultimately, if you are concerned about security, malware scanners will quarantine malware, which helps reduce problems. But it does not keep your websites malware-free.
If a loophole exists in your scripts, no matter how often the malware is quarantined, it will just continue to infect/inject into the account.
The best and most reliable solution is still to
- Only install trusted scripts.
- Keep scripts up to date.
