About Virus Checker

Virus Checker is a browser extension designed to automatically block spam websites and alert you when you encounter them. With Virus Checker, you can customize your browsing experience by blocking intrusive ads, disabling tracking, and much more. It is available for all major desktop browsers as well as mobile devices. The extension uses filter lists—sets of rules that determine which elements should be blocked. Most of these pre-made lists are created, published, and maintained by the community under open-source licenses. Since many ads contain trackers and some may even carry malware, Virus Checker includes built-in protection against tracking and malicious content by default.
