Ads keep popping up, saying I have an extension called 'None Extension'. I looked for it in add-ons under extensions and plug-ins but I didn't find it.
I looked for an add-on I supposedly have on Firefox called 'None Extension' with no luck. Ad's continue popping up all the time, saying they're powered by this extension. Google won't show me anything about it either and I didn't find it under extensions or plug-ins in add-ons but I didn't find it. What should I do?

You can check for recently installed suspicious or unknown extensions.
You can do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.
