How Did I Get Infected with Kittyads.com?

The hijacker rarely installs with your express consent—it sneaks in with freeware, suspicious browser add-ons, or fake updates. Even extensions from official stores can hide rogue behavior. Visiting high-risk sites or clicking misleading ads or CAPTCHAs can trigger the infection, and leftover adware components may help it reappear after removal.

What Kittyads.com Does to Your Browser

Once active, Kittyads.com hijacks your browser by changing your homepage, search engine, and new-tab page. It pushes intrusive pop-ups and banners, redirects your searches to sketchy third-party sites, and tracks your browsing habits to fuel targeted ads or worse. It may also use hidden files or extensions to re-establish itself after removal.

Should You Be Worried About Kittyads.com?

Yes. While technically a potentially unwanted program (PUP) rather than malware, its behavior is highly intrusive. It slows down your system, compromises your privacy, and can redirect you to malicious or phishing websites—exposing your system to further threats.
