I've been using Comodo Firewall with no antivirus or infection for nearly two decades now. I prefer it for its protection, usability, features, and configurations, and it runs light on the system. If not Comodo, I would use @Andy Ful's tools or CyberLock.unclear why "not for long"? -- I've been using it continuously for at least a decade with no malware, few false positives. Website says "install & forget" and that has been my experience 99.9% of time. But agree about about OFF name but if you install & forget that's not much of an issue, imo.
Does whitelisting the folder or vendor allow the program's updates or new versions with no alerts?@rashmi CL/VS doesn't work like Comodo, you can whitelist folder and even whitelist the vendor.
