WebWatcher found, question on source

Recommended Posts

Greetings, thanks for your time and help.  

Malware Bytes detected an instance of WebWatcher in my registry (PUP.Optional.WebWatcher)  .... in a registry location apparently associated with the Adware LookSafe.....

I'm in my 30s, living alone.... So no one was authorized to install the commercial version of the monitoring program on my PC. 

I have two quick questions:

1) Is there any way to analyze the registry entry/Malwarebytes quarantine item, and find out if in fact someone actually installed the program on my computer physically with a thumb-drive etc.? .... If that's the case I need to immediately reevaluate who I am inviting into my home, I think!

2) Is there any way to tell if this instance of the program is for adware-generation or something more malicious like logging keystrokes and even accessing the microphone? I ask because I am considering switching all my passwords

Forgive my ignorance on this please. I was pretty terrified that this thing has been lurking on my PC for months. Definitely was the most serious infection I've had in years.

Thank you. I think MalwareBytes has separate narratives for pup-optional-webwatcher and the adware-employed version. I'm really worried about the source of the file and who if anyone has been illegally spying on my PC

I don't know if this is relevant at all to your situation but it might be useful nonetheless.  There are several entries in the Malwarebytes Labs blog about spyware and stalkerware such as this one and this one that may provide valuable information.

You can also have your system analyzed by one of our malware removal specialists to make sure there's nothing else malicious on the device by following the instructions in this topic and creating a new topic in our malware removal area by clicking here and one of our malware removal specialists will assist you in checking and clearing the system of any remaining threats.  If you prefer to be assisted privately you may instead contact Malwarebytes Support directly via any of the options found on this page.

I hope this helps, and if there's anything else we might assist you with please let us know.

By the way, I also found a couple more articles relevant to this type of spyware here and here and I'd definitely suggest checking your smart phone if you own one to make sure nothing has been installed on there.  You can seek help from Malwarebytes Support with that or you can create a new topic here to have your device checked for threats, and if you haven't done so already, I'd definitely recommend installing Malwarebytes on your mobile device to scan it as well.  They have versions for Android and iOS available on the Google Web Store and Apple App store.  You can learn more here as well as here.
