What's the Best Way to Secure an SMB Server Without Sacrificing Performance? or Why Is My SMB Server

Yikes, SMBv1? That’s like driving a Model T on the highway. Upgrade to SMBv3—it’s faster and way safer.

And yeah, antivirus scanning every file is brutal. Exclude the SMB share or schedule scans during off-hours.
