Legitimate ad blockers will not hurt your computer, but keep in mind that some website features/functions might not work. If a web page doesn't load correctly, if you can't see icons or links, videos won't play, the comment section isn't showing, etc., disabling the ad blocker for that site should be the first thing you check. There should be an icon for the ad blocker app displayed on your browser toolbar that you can access to enable/disable blocking on individual pages, or temporarily turn it all off.
Some sites don't allow ad blockers at all; those will typically show an onscreen message to that effect.
