It looks like some malicious ads made their way to Skype this week. These ads push a download that is made to look like a Flash update, but instead reaches out and downloads malware, most likely ransomware. It looks like the domains used for Command and Control are currently offline, which is a good thing.
Just remember that it’s better to go to the Adobe Flash website to download updates, or even use the daily obnoxious update notifications in your taskbar, as opposed to clicking on something pushed to you through a browser.
