Website & Phone:
I found this website at the top of a google search as I needed a duplicate file finder. It claims that its:-
"#1 Rated Application as Reviewed by Trustpilot.com"
(Which is MORE than odd, as it appears nowhere here on Trustpilot, and as far as I can see, my review is the very first entry for it…).
The page looked a little odd, so I tried just entering the main duplicatefilesfixer.com site by deleting everything after .com in the url, this led me to a different download link (and download content, the files were both different). Unfortunately, this time Firefox itself warned me that the download "was not a common one and may contain malware".
Upon attempting to install either download..
Malwarebytes INSTANTLY quarantined them both as containing a PUP. – it attempts to install something called "Systweak v2.1".
My advice is… don`t touch it with a $hitty $tick….
