Quite honestly I don't know where to put this question since it doesn't seem to fit neatly into any existing section of the forum. System: desktop Windows 7 64 bit. I'm currently running a version of the MVPS HOSTS file that I installed in 2012. A few minor tweaks to block a couple of other websites. For me the main issue is to keep the ads off my screen and it has done so nicely ever since I put it on the computer. These days, occasionally I see an unwanted ad but nothing really bad. I've seen what a screen filled with ads can look like. The thought occurred to me to update the MVPS hosts file, and I may have experimented with that years ago. I don't remember to be honest. Quite possibly the size of that HOSTS file has increased dramatically, I'm not sure by how much. This system is almost a decade old, and I really don't want to slow it down. Sometimes I can just notice that accessing the web is a bit slower than a decade ago. Insight, opinions, options ? The idea of updating that file occurred as making this computer a bit more 'future proof' since I have absolutely no intention of installing Windows 10. But if it's going to be just another drag on resources I'll pass. Current main browsers are Palemoon and to a lesser extent IE 11.
