I just wanted to correct my above post, as some might misinterpret what I was trying to say and take offense;
Tunngle is not responsible for the ads it displays, as it gets them directly from an ad farm that does the filtering and whatnot. Ads may contain malicious content, but I have never seen anything of the sort on Tunngle. I didn't mean to cause anyone any offense, or try to harm the development team in any way.
Sometimes malicious ads do make their way around the internet, but you honestly can't blame those who display the ads, they have no control over it... Sure they can report it and ensure it doesn't happen, till it happens again, such is life, there are always assholes that try to ruin things for us.
So at the end of the day, it is up to us, the end user to ensure we're properly protected and know the risks we take when entering the online world.
I'm pretty sure it's not my PC, as I work in the sector where this is a daily thing for me, and I personally have 10 years experience. But like I said, if anyone has an issue there is two alternatives; 1) use an ad blocker and starve the developers or 2) upgrade to Premium
and do away with the ads whilst ensuring the best Tunngle experience for everyone (which I hope to one day do as well...).
