Do you have the app? [https://github.com/nextcloud/files\_antivirus](https://github.com/nextcloud/files_antivirus) ---

Will this be a good idea to run sth like this on a small ARM? (e.g. raspberry pi? 😃 ) ---

Depends on the number and the size of file uploads you plan. Test and monitor the CPU load I’d recommend. ---

Hello, I feel It takes a long time although the size is small. Probably I should tune the app or clamAV. I will research clamAV conguration. ---

A RPi3 is probably too lightweight for some serious scanning. I had files\_antivirus installed on NC9 and it really slowed down the uploads of larger files, even on a 4 vCPU XEN guest. Also, this will limit the size of the files you can upload, since clamd will only be able to scan files, that fit into the main memory. I think though, that you can offload the scanning onto some other host, which then shouldn’t be a RPi, obviously. ---

Hello, Thank you for your suggestion. Because now not yet started the service for users, I deactivated NC13 antivirus. My KVM server has 3CPU.when scanning going working slow. I will try to scan from another server that implements clam daemon. ---

Even if you have clamav running locally please consider using the daemon mode (socket). This is significantly faster. ---
