Most anti-virus software causes a dramatic increase in disk IO and CPU Usage and Atlassian has recommended to limit virus scanning to certain directories

The Hidden Risk

Apart from the performance overheads, some virus scanners delete the infected attachments silently in the backend after the file has successfully uploaded.
