The JS/Agent is a heuristic detection used by some antivirus programs to identify a potentially unwanted program on your computer.

The JS/Agent is an adware program and goes beyond what the standard definition of “potentially unwanted program” should mean. Most people lump anything from adware to spyware as a potentially unwanted program but the seriousness of adware makes it more of a “definitely unwanted program” that must be removed immediately before you can start using your Web surfing experience again.

Adware is a series of advertisements that sit ontop of the web browser and will continually display themselves when you open webpages. These ads are not part of the usual ads that you get from the websites themselves—they are typically of lower quality, will make your PC howl because of the heavy load they put on your hardware, and create so much clutter due to it being an extra layer of ads on top of the ones you’re already getting from the websites themselves, that Web surfing becomes a disastrous experience.

Nobody benefits from the advertisements that are shown from adware packages but the developers of the adware themselves. All the times the adware is showing on your screen the developers are collecting revenue for thise views, which is why they create it.

The good news is that all adware can be removed. All you need to do is install one of the trusted and reliable adware removal tools on your computer and then run a scan with it as you would with any antivirus software. Adware scans are generally completed much quicker than antivirus scans so you won’t have to wait very long before your Web browsing experience is back to normal again.

This tutorial demonstrates how to remove the JS/Agent adware from a computer.

How to Remove JS/Agent adware

1. Head to the official AdwCleaner webpage from Malwarebytes and click on the “Free Download” link toward the bottom of the page.

2. If your browser gives you a notification that says “This type of file can harm your computer. Do you want to keep the adwcleaner_x.exe anyway, click on the “Keep” button.

3. Click to open the AdwCleaner file once it has finished downloading.

4. If User Account Control prompts you, click on the “Yes” button.

5. Click on the “I Agree” button when you get to the welcoming and license agreement screen.

Click on the “Scan Now” button to scan your computer of adware and potentially unwanted programs.

The AdwCleaner tool will now quickly scan your computer and find the threats.

Click on the “Clean & Repair” button from the Scan results page to clean the computer.

You can choose to “Clean and Restart Later” or Clean and Restart Now” depending on what suits your needs. Any unsaved work will be lost if you proceed to shut down now, but you’ll want to shut it down before expecting your computer to be ridded from the adware.

After a few minutes, the AdwCleaner interface will automatically open itself up on your computer’s display once again and show you the results.

Any adware that was detected will now be held in the “Quarantine” section of the AdwCleaner program. You can if you prefer still uninstall the AdwCleaner from your computer after you’re finished your scans and still expect to browse the Web without seeing the adware that you were before.

That’s all.
