If your Macbook antivirus is giving you too many virus alerts.
If you are using your mac mail application with our gmail or other webmail, your spam folder is been synced to your mac with all the virus attachment from your spam folder. Your antivirus antivirus will scan them and show you a popup alerting your computer might be infected.
There is no risk here but to avoid this you can go to your gmail settings and uncheck “Show in IMAP” from the Spam folder. Your spam and viruses will no longer be synced to your Mac.
