Love this graphic that explains Malvertising from Malwarebytes
So what is Malvertising ?
Stands for Malicious advertising that infects your computer with malware and in many cases popup ads that will not go away.
So how do you get it .You visit a website – the threats lie in the ads and these ads ( selected ones ) are designed to infect peoples computers
So how do you protect yourself – your computer from Malvertising.
An Adblocker combined with an effective antivirus solution will help combat this currently.
