FF 72.0.1 - warning says I'm using an outdated version of Chrome

This morning I get an error (not what I would call a true pop-up) about using an outdated version of Chrome. I researched the issue on another computer while I ran some malware scans. According to my findings, the likely culprit would be a recently installed addon (adobe flash was updated this morning). I do not have adobe set to automatically update, so I uninstalled it via Revo Uninstaller. The MalwareBytes scan revealed quite a few PUP warnings, and they were quarantined. I'm now getting an error when I try to log into Gmail, saying I am trying to run an insecure browser or app. Virus scan does not reveal anything. Using FF in Private Browsing mode gives no errors logging into Gmail.


Any insight and troubleshooting ideas would be most welcome!

DealerMan,
Not sure, some googling from malwarebytes forum

Snick, many, many thanks for the recommendation. My Google-fu is lacking, apparently! I knew there was something from my past I couldn't remember, and it was AdwCleaner (although I could not for the life of me find it in my history here on W7). Either way, I'll be able to try your suggestions later this evening. I'll keep you posted.

DealerMan,

ADWCleaner was originally and still is available from toolslib.net, I believe a french site. Says publisher Malwarebytes.

Malwarebytes includes it as part of their product family now also.

I found the culprit. Apparently, I installed a user agent addon in FF that I had long forgotten about. After following the steps here, I was still getting an error. Uninstalling the addon cured my woes immediately.
Snick, thanks again for your help! Hopefully my mistake will help someone in the future!

You're most welcome.
Sorry for the delay, been without internet, phone, cable TV for a few weeks.
