Hi. I'm having the same problem and I already had the "detect other software" option enabled. I have not installed any new programs, apps, or extensions recently and this is only happening with the Chrome browser. A scan doesn't turn up anything. I'm getting "download blocked" from jonysource.com notifications every time I open a new tab or reload a page. Someone needs to notify the virus/malware database people at Kaspersky about this issue. If Kaspersky can alert me to a problem, but the scan doesn't find anything, that's a problem on Kaspersky's end. Malwarebytes Premium can't find anything, either, which leads me to wonder if it's a false alarm. Can someone at Kaspersky please look into resolving this issue? We can't be the only ones having this trouble and you're going to have a lot of disgruntled customers on your hands.
This is what KIS keeps telling me the web address is: https://jonysource.com/213db6bf854a.js
jonysource.com doesn't exist, so I don't understand how this malware is originating from a nonexistent site.
