Frankly, it doesn't make any sense to me how I can be compromised while using it.
And I only took this into consideration because my Starcraft II account has been hacked before. I've only been hacked twice in my life, both times a Blizzard product, and this time I had that extra security from their very own product. This is a disgrace.
