removing ads by browse to save

Go here & try AdBlock or one of the other Safari extensions that block ads.

Safari/Preferences/Security - do you have 'Block pop-up windows" checked.

You might want to consider removing MacKeeper. It has caused a lot of problems for some people.

MacKeeper – Do Not Install

MacKeeper Removal

From the Safari menu bar, select

Safari ▹ Preferences ▹ Extensions

Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.

Read the comment by SDW2001 in this thread.

Remove "MacKeeper" as follows. First, back up all data.

"MacKeeper" has only one useful feature: it deletes itself.

Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.

IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.

In the Finder, select

Go ▹ Applications

from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the functional components of the software will be deleted. Reboot.

Failure to remove MacKeeper will result from neglecting any one of these points:

Quit MacKeeper before dragging it to the Trash.

Don't empty the Trash after dragging the application to it. Let MacKeeper delete itself.

Don't try to drag the MacKeeper icon in the Dock to the Trash.

Here are some general suggestions. If you want your computer to be usable, don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless.

The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.

The only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Never install any third-party software unless you know how to uninstall it.

Linc's advice is excellent except for one possibly misleading statement: there is no "culprit" that causes ads to appear in browser windows. That's just something many web sites do to get revenue from ad placements, more or less the same way commercials are inserted in TV programming to generate revenue for the station or network.

There are extensions (ADBlock being one of them) that prevent most ads from appearing in web pages -- they don't load & you just see a blank space where they would be. You could consider them an "anti-culprit" of sorts, the culprit being the web site that puts the ads there in the first place.

To avoid confusion, I should add that there are Safari extensions that inject ads into the HTTP stream. You may have installed such an extension.

Also true!

"I wish I didn't waste my money on MacKeeper!"

If you had $1 for every time somebody had said that, you'd have made your money back 40x over 😁
