- A
Run System Restore to a point before installation.
Why wrong: System Restore may not remove all remnants of the PUP, and it could revert other system changes.
- B
Use a dedicated adware removal tool and then reset the browser.
Adware removal tools are designed to find and remove PUPs that standard antivirus may miss, and resetting the browser cleans up leftover settings.
- C
Manually delete the program from Program Files.
Why wrong: Manual deletion may leave registry entries and browser extensions intact, leading to recurrence.
- D
Disable the browser's JavaScript and ActiveX.
Why wrong: Disabling scripting does not remove the installed PUP or fix the homepage and pop-ups.
Question 146 of 750
How to Remove PUPs and Restore Browser Settings
This 220-1202 practice question tests your understanding of browser and application security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user reports that after installing a free PDF converter from an advertisement, their browser homepage changed and they see constant pop-ups for antivirus software. A malware scan found PUPs (Potentially Unwanted Programs). What is the best next step to fully remove the unwanted software and restore browser settings?
Quick Answer
The answer is to use a dedicated adware removal tool and then reset the browser. This is correct because PUPs and browser hijackers often embed themselves deeper into the system than standard malware, using registry entries and scheduled tasks that a typical antivirus scan may miss; a specialized adware cleaner targets these specific persistence mechanisms. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of removal procedures for bundled software threats, a common troubleshooting objective. The trap is choosing to simply run a full antivirus scan again, which often fails to fully eradicate PUPs, or manually deleting browser shortcuts without resetting settings. Remember the two-step rule: clean with a dedicated tool, then reset the browser to wipe all hijacked configurations. A helpful memory tip is “Scrub then scrub the slate”—first remove the PUP, then reset the browser to factory defaults.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a dedicated adware removal tool and then reset the browser.
Option B is correct because PUPs often embed deeply into browser settings and registry entries that a standard uninstall or System Restore may not fully remove. A dedicated adware removal tool targets these specific traces, and resetting the browser ensures all malicious extensions, search providers, and homepage hijacks are cleared, restoring default security configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that System Restore (Option A) is a comprehensive fix for malware, when in reality it may not remove PUPs that persist in user profile folders or browser data that are excluded from restore points.
Detailed technical explanation
How to think about this question
PUPs often install as browser helper objects (BHOs) or use Windows Task Scheduler to re-spawn after deletion, requiring tools like AdwCleaner or Malwarebytes AdwCleaner to scan for these persistence mechanisms. Resetting the browser in Chrome (chrome://settings/reset) or Edge (edge://settings/reset) clears all extensions, cookies, and site data, effectively removing any injected search providers or homepage URLs stored in the browser's preferences file.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles
2 more ways this is tested on 220-1202
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. During a security audit, you discover that a user's browser has multiple pop-up windows appearing, even when no websites are open. The user denies installing any software. Which tool should you use to identify and remove the underlying cause?
medium- A.Reset the browser settings to default
- ✓ B.Run a full scan with Windows Defender or another anti-malware tool
- C.Disable JavaScript in the browser
- D.Clear the browser cache and cookies
Why B: Pop-ups appearing without a browser suggest adware or a potentially unwanted program (PUP) running as a background process. Using Windows Defender or an anti-malware scanner is the correct approach. This tests understanding of adware behavior and removal tools.
Variation 2. A user calls the help desk complaining that their browser homepage keeps changing to a site they did not set, and they cannot change it back. You remotely check and find no malware. What is the most likely cause?
easy- A.The user's browser profile is corrupted.
- ✓ B.A recently installed program modified the browser settings during installation.
- C.The user's DNS settings are being hijacked by the ISP.
- D.The browser's shortcut target is pointing to a different URL.
Why B: Option B is correct because many legitimate software installers include bundled programs or browser extensions that modify the default homepage, search provider, or new tab page as part of their installation routine. Even without malware, these changes are often made via registry keys (e.g., HKCU\Software\Microsoft\Internet Explorer\Main\Start Page) or browser policy files, and the user may not have unchecked the relevant option during setup. Since no malware was found, a recently installed program is the most likely cause of the unwanted homepage change.
