I can't give a whole lot of specifics, but I've seen this more than once. I've had Icy Veins open on the Genji build guide for HotS for no longer than 15 minutes and suddenly, AVG force-minimized my game to let me know it closed my connection to a site with a pretty fishy URL. For the safety of others I'm not going to post it here, but I'll PM it to a staff member if I can get a name and a way to do so (just made an acc for this, idk how)
This must be from Icy Veins as if I hit back on it, it returns to the forum every time. It's happened around four times now, and didn't begin happening until I decided to turn off uBlock for Icy Veins.
Precisely, AVG says: "We've safely aborted connection on {URL} because it was infected with URL:Mal."

Recently came across this ad on your site...selling kills/mounts/etc
Seems bad

Hey guys, first of all I love your build guides for WoW and HotS.
 As a marketing professional who works with ads all day, I can tell you, you really need to review your ad suppliers. I keep getting auto routed to malware install pages. (Your chrome/phone/computer is infected, install our software to clean it up!) Which then prevent use of the back button to return to your pages. This is extremely frustrating and can be damaging to your users. This happens on both my Android and desktop, and is becoming more frequent. Yours is the only site I visit that does this.

That you know how to make ppl disable aDblock for this site.
 
Lol.
