Browser Hijacker: What it is, signs to spot, and how to remove it

What it is

What you may notice

• Homepage/search engine swapped; new tab opens to a strange site

• Extra ads, pop-ups, and random redirects on normal pages

• New toolbars or extensions you don’t remember installing

• Sluggish browsing, high data use, fast battery drain

How it gets in

• Bundled with “free” installers or fake updates

• Rogue extensions from untrusted sources

• Drive-by downloads and deceptive ads

Fix it now (quick steps)

1. Remove unknown extensions; reset the browser to defaults.

2. Uninstall suspicious programs; reboot.

3. Run a full anti-malware scan to clean leftovers.

4. Check DNS/proxy settings; set back to automatic if changed.

Prevent it

• Install software and extensions only from official stores.

• Choose Custom install and deselect extra offers.

• Keep your browser and OS updated; use real-time protection.

• Be cautious with “free” video codecs, PDF viewers, and cracks.
