I think it’s a PC. Someone told me about adblocker. You get it online, it’s free and it’s not too hard to figure out how to download. I did it myself, and I’m not very technological. I don’t know why everyone wouldn’t get it.
It’s the only filter I have right now. I should get something else, but I haven’t figured out yet what or how. This was great because it was free and easy and because I didn’t have to worry that it might block something that I don’t want blocked. Also, ads are the biggest problem and the main thing I would want blocked anyhow. But it’s not really enough.
