I've been using Couchtuner for probably 5 years now and I've never had a problem. However, I never download anything. Instead I look for the SMALL GREY X to the side of the ad almost hidden behind and shut it down. Now I may have to do this twice because a second ad might come up, but as long as I hit the SMALL GREY X it closes with no problems. I've been recommending Couchtuner for years to my friends and family and I let them all know you have to X out the ads/updates. The only reason I found this website was because I was trying to compare couchtuner to steamtuner, because it offers movies as well as tv shows, so I thought I'd throw in my 2 cents.
