Difficulty: EasyWeb Browser Security and Pop-Up/Redirect Troubleshooting

A user reports that after installing a third-party toolbar, their web browser continuously displays unsolicited pop-up advertisements and redirects search queries to an unknown search engine. A technician inspects the browser and discovers an unrecognized add-on. Which of the following is the best initial action to resolve this issue?

  1. Remove the suspicious browser add-on and reset the browser to default settings.Answer
  2. B
    Clear the web browser cache, cookies, and browsing history.
  3. C
    Perform a complete clean reinstallation of the operating system.
  4. D
    Rebuild the local file search index using Indexing Options in Control Panel.

Answer

Remove the suspicious browser add-on and reset the browser to default settings.
Removing the suspicious browser add-on directly eliminates the software component responsible for pop-ups and redirects, and resetting browser settings restores the legitimate default search engine and home page.

Step-by-Step Solution

1
Identify the cause of the redirect and pop-up behavior.
The unfamiliar browser add-on and modified search settings are confirmed as the source of the browser hijacking.
Unsolicited redirects and persistent pop-up windows following a toolbar installation typically stem from rogue extensions.
2
Remove the extension and restore default browser settings.
The unwanted add-on is uninstalled, and the default search provider and homepages are restored.
This directly remediates the browser hijacker at the application level.
