Antivirus for Icinga

Hello Icinga community,
In the news lately there has been some reports that hackers are attacking Linux server more now. I am looking to adding antivirus software to my Icinga servers. Does anyone have any antivirus best practices or recommendations? I did not find any antivirus details in the Icinga online documentations.

Will the antivirus software slow down the Icinga2 application? Should I exclude the icinga2 process from the scan? Any other recommendations will be awesome.

Thanks in advance for your time.
Alex
