Windows 7: Xmarks Authentication popup window

In the past two days a tremendously annoying popup window has started showing up about every minute and a half. It is labeled "Xmarks Authentication" and it asks for a username and a password. I don't have any idea where it came from. I have run a McAfee scan with no result, and have searched the hard drive for "Xmarks*" and found nothing.

Any help getting rid of this nuisance would be much appreciated.

Thanks.

Hi, welcome to the forums

Have you installed any new software recently? You may have become a victim of Malware. Download and install MalwareBytes and immediately perform a full system scan.

Not sure if this is your issue. Are you running FireFox? There is an Xmarks bookmark syncing service addon that may be causing the issue. They recently shut down their servers: Xmarks Shutting Down Syncing Services at the End of 2010 - Tested

If you are running Firefox, you could use Tools/Addons to uninstall it. You could also check Addons in IE and check in Control Panel\Programs and Features.

The best thing to do is to simply login to your Xmarks account!

If you want to stop running the application you can right click in the tray area of your browser and then find the blue X from xmarks and right click and shutdown or remove the Xmarks for IE program from the Windows control panel -> Add Remove software.

Thanks to all that have replied. As Orbital Shark suggested I dl'd and am running (even as we type) the Malware program; so far it reports 6 objects infected - but it is still running.

This just in: the malware program finished and reports 14 incidents of malicious software on this system (what the dickens is McAfee doing for me?). I will let that program remove these and see if that solves the problem

James: I do have Firefox installed on this machine but mostly use Chrome. I will, however, do the checks you - and Joelastpass - have suggested.

Thanks to all for your timely replies. I will report back in a day or so to let you know if it is cleared up.

Thanks again.

Thanks again to those who responded. Kudos to Orbital Shark as his link to a malware removal program seems to have done the trick. Everybody's help was\is much appreciated.

I know what it is... It's an add on to google chrome, it's a back up place to store & recover your book marks if you ever need to... I just downloaded it from the google's chrome web store... it's popping up on me as well & I am not sure what to do next with it... will ask my son tomorrow... he'll know
