I have an HP laptop using win 10 home, win defender, win firewall, and malwarebytes anti malware which is monitoring my laptop while in use. While using my laptop the other day, I received and unsolicited popup, small, from the right of the screen stating a female name was inviting me to link to her on SKYPE. I wasn't on a web pate at the time. This has never happened before. I checked the Settings< Privacy > Apps section and of the four options listed, the only one enabled is 'turn on smart screen filter to check web content'. The other three I turned off when I bought the laptop. I also checked the Background apps section and SKYPE is not listed (although when I got the pop-up I searched for SKYPE and then deleted it from the search results window). I haven't gotten that message since last Wednesday but why did I get it at all since I never installed or enabled SKYPE prior to this incident and how did I get the intrusion? I guess what I am asking is, is Malware anti malware bytes in combination with win defender and win firewall sufficient to prevent that kind of intrusion because the intrusion happened after I updated defender, firewall, and malwarebytes.
