Webroot scans were coming up clean, but Malwarebytes caught something.
I recently went to Scribd.com while searching for a movie script. I downloaded the free file viewer they offered and I immediately started having some problems with my laptop. I scanned my PC using the SecureAnywhere Complete and the scan came up clean. I then used the Malwarerbytes PRO and it came up with a PuP file that had been incorporated within the free file viewer I had downloaded. NOT compaining about anything, I'm just a little confused about why Webroot didn't catch it, but another program did? (Sorry, before you ask, I have already deleted the file and my computer is back to normal. So, I can't provide any file names for you. However, if you want to research it, that is why I gave you the site name and the product I downloaded.)

I am going to attempt to replicate this on my system to see exactly what is what! :-)
More to come!
Alright, I downloaded the Free File Reader tool and installed it (opting out of all of the free toolbars [Yahoo], etc.).
Then I ran a scan with SecureAnywhere and Malwarebytes Pro and came up with nothing. Hmm ... so I uninstalled the Free File Reader tool and then reinstalled with all of the free software and toolbars to see if it made a differance in the results, however, it did not. Both of the Malwarebytes Pro scans came back PuP free.
From a Security Forensics point of view, it becomes challenging going forward, since I can't reproduce the issue and you have already removed the file (I don't blame you for that one, if a file even looks at me wrong it gets zapped! LOL).
With that said, your Malwarebytes Pro probably has a log file from that scan (it retains a log file for each scan by default). If you open the Malwarebytes Pro interface, you will see a tab marked Logs, then you will see logs from all of your scans. If you open the log in question, it should have a reference in there as to what software (PUP) it found.
If you can locate that and post it hear (or the entire log contents if it isn't exceedingly large) I am more than happy to run with it and see what I can determine on the backend.
The tough thing about Potentially Unwanted Programs is the "Potential" part ... meaning its a best guess. Sometimes valid, sometimes not.
I also wanted to say "Way to go!" on just remaining vigilant, that is SO cricucial to good cyber security!
Let me know what you find and maybe we can unravel this mystery! 😉
Thanks for your efforts though! I will save the pertinent stuff next time. (hopefully, there won't BE a next time though.)
