Question For Internet Wizards

Why is my browser history filled with "google leads.double-click net" entries?

And, how can I avoid it?

Can't say I know the answer to that one. Sounds like it's picking up ad loads as site visits - not sure why it'd be doing that though. Would help to know the browser. I can't imagine any of the majors making an error like that.

If you clicked an ad, though, that might do it. I would still think it'd only drop the redirected site, and not the ad link itself, into the history, though.

Run Spybot Search & Destroy; It's good and free.

Hmm didn't consider malware/adware. Wouldn't hurt to check.

Most likely ad related - I used to have that problem, mostly in IE. Install AdBlock Plus and see if it goes away like it did for me.

if running firefox, you can have several add-ons to address this

One is Block site 1.1 that allows you to block individual websites ....

"Referrals from googleads.g.doubleclick.net are clicks on your AdWords ads showing on the Google Display Network - specifically, ads showing on publisher sites in the AdSense program - for which the destination URLs have not been tagged.

If you notice googleads.g.doubleclick.net appearing in your reports, check to see if auto-tagging is turned on in your AdWords account, and that your own campaign variables are labeled correctly."

I run Chrome in Private mode. It deletes the history, cookies, etc when I exit. This does make me have to sign in everytime I access a site because it doesn't store my passwords.

Adblock plus is a great add-on for firefox, provided you un-check the "Allow non-intrusive ad's."
