The most effective way to stop a zip bomb from reaching your computer is to have an anti-virus program running at all times and regularly updated. Anti-virus software and firewalls are essential for protecting service providers and users from malicious files like the infamous Zip Bomb.  These programs detect and block dangerous codes, filtering out malicious fragments from files before they can reach your device. Additionally, it would be best if you were vigilant with file downloads — any suspicious or unfamiliar files should be avoided. If you download a ZIP archive, scan it first using either a local or online scanning service. It's also important to be mindful about not opening ZIP files from unsolicited sources — even if sent by someone you know — as these could contain malicious code that could compromise the security of your device.
