Searchfeedtech.com is a kind of malware that adds advertising links in your Google results. Here's how to remove it
Surely you have noticed that this malware only works on Chrome or Chromium browser. It is therefore malware that is embedded in Chrome, and more precisely in an extension.
How does searchfeedtech.com work?
This malware is actually a simple script that runs in the background and inserts links to Google results. You can spot it using the browser development tools (F12 key).
After some research, I understood that the script was provided by an extension for Google Chrome. So I deactivated my extensions one after the other to know that it was the extension in question. I realized it was the “Page Ruler” extension. An extension yet very practical for measuring widths or heights when creating websites.
To avoid amalgamating with other extensions named “Page Ruler”, I am talking here about the extension which has the id: jlpkojjdgbllmedoapgfodplfhcbnbpn
The app hasn't been updated for a while and has been deleted from the Chrome Store. It nevertheless remains functional on browsers where it has not been deleted.
How to remove searchfeedtech.com?
Just deactivate the Page Ruler extension and remove it. Your search results will then return to normal.
If you can't find the “Page Ruler” extension, it's another extension that injects the script. Indeed, it's not just Page Ruler that does this, other extensions have already done it and others will do it again. So you have to deactivate your extensions one after the other to know the malicious extension.
For those who wanted to Page Ruler, do not worry there are some similar extensions on the Chrome Store: https://chrome.google.com/webstore/search/page%20ruler
