I want to install Antivirus in SpectroSERVER and OneClick, is it advisable?
If you go through the Spectrum Installation Section under the topic Virus Protection Exceptions for MySQL it states that you can install the antivirus to protect your network environment but exclude the CA spectrum installation areas.
For your reference I am pasting the content from the installation document.
Antivirus Software and Data Backup
CA Spectrum does not include antivirus software. We recommend installing your preferred antivirus software to protect your networking environment.
Important! To avoid database corruption, exclude CA Spectrum installation areas and CA Spectrum files from scans by any local or remote instances of antivirus software. CA Spectrum installation areas include Oneclick and Report Manager installation areas.
Exclude all CA Spectrum installation areas, including OneClick and Report Manager installation areas, from scans by data backup programs.
