The “System Files Altered” pop-up is a browser-based scam that displays fake error messages to trick you into subscribing to a service that you don’t need.
What is “System Files Altered”?
The “System Files Altered” fake error message is a scam that is shown to trick you into thinking that your computer is infected with malware. It does this to scare you into buying an antivirus license so that the scammers can earn a commission from the sale.
The “System Files Altered” page will display these alerts:
System files altered!
Suspicious software installed. Run a scan if it wasn’t you.
Avira: system files damaged
Trojan detected Click here to remove
As you can imagine, the above alert is not real and its purpose is to scare you into purchasing services that you don’t need. If your browser has been redirected to the “System Files Altered” page, we recommend closing it and ignoring any alert that it might show.
Why am I seeing the “System Files Altered” pop-up ads?
You are seeing the “System Files Altered” pop-ups because your device is infected with malware, malicious push notifications, or a site you have visited has redirected your browser.
Less than reputable sites can display malicious ads that redirect your browser to the “System Files Altered” pop-up scam to generate advertising revenue. If this happens, you can close the page and install an ad blocker like AdGuard to block the malicious ads. However, if you are continuously seeing pop-ups like the “System Files Altered” pop-up scam, then your computer might be infected with a malicious program and you need to scan your device for adware and remove it.
Here are a few typical signs that you have a malicious program installed on your computer:
- Advertisements appear in places they shouldn’t be.
- Your web browser’s homepage has mysteriously changed without your permission.
- Web pages that you typically visit are not displaying properly.
- Website links redirect to sites different from what you expected.
- Browser popups appear which recommend fake updates or other software.
- Other unwanted programs might get installed without your knowledge.

To reset these policies, follow these steps:- Open a new Terminal window. To do this, go to Finder > Go > Utilities > Terminal

- After running these commands, quit Chrome if you haven’t already done so, then launch it again and check chrome://policy to see if the same keys are still present (you may need to click the “Reload policies” button for changes to show up). If they’re gone, you should be able to change your search engine and home page back to your preferred defaults in Chrome’s settings.
-

- Type or copy/paste the following path into the window that opens, then click Go: /Library/Managed Preferences/
- Paste the below path into the window that opens, then click Go:
Look for the following files, where [username] is your username:- com.google.Chrome.plist
- [username]/com.google.Chrome.plist

These may be legitimate, so open these files with TextEdit and see if they have links to the troublesome site in them. If they do, delete them and restart Chrome.
