If you notice an excessive number of pop-up ads, unexpected browser redirects, or unauthorized changes to your search engine settings, WebGuard may be responsible. Identifying and removing it promptly is crucial to restoring your browser’s security and performance.
What Is WebGuard?
WebGuard is a deceptive ad blocker that falsely claims to enhance online security by preventing unwanted ads. However, instead of providing real protection, it operates as a browser hijacker and potentially unwanted program (PUP) that injects intrusive advertisements, redirects users to malicious websites, and compromises system performance. Many users unknowingly install WebGuard, believing it to be a legitimate ad-blocking tool, only to experience an increase in pop-ups, browser slowdowns, and security risks.
Cybercriminals often distribute WebGuard through software bundling, misleading advertisements, and fake download links. Once installed, it modifies browser settings, manipulates search results, and tracks users’ browsing behavior for targeted advertising.
