On CCleaner under cookies to delete or cookies to keep, how can I tell what each cookie is?
Example:ambr.net how can I find out what this is?

If it's a site you don't recognize it's probably not something to bother keeping. That "ambr.net" is just some unregistered domain, not worth keeping in my opinion.

Now if you have a site you always visit with customizations like your homepage, etc., you could keep those, or forums you visit to keep your login information valid.

But is there any way to find out exactly what those cookie names are,some of them are just numbers.Ther must be a way to find out I tried right clicking and that doesn`t work.

Cookies Are plain text and can read read in Notepad but they won't give you much info as to what the site/issuer is

You can use ieCookieView from Nirsoft http://www.nirsoft.net/utils/iecookies.html

or if you use Firefox http://www.nirsoft.net/utils/mzcv.html in Mozilla Cookies View

Personally I don't like cookies and temp files. I delete them all with CCleaner. I often times block cookies all together via IE -> Tools -> Internet Options -> Privacy -> Advanced. A cookie is a document. Should a document be installed on my PC or not? Well, I'll be the judge of that, thank you very much. The cookies I want is kept in CCleaners "Cookies to keep". The rest is deleted or not let in at all in the first place.

Think about that: who are those people who installs documents on you PC? Are you really sure you want them to do that?

Note: blocking cookies will give you problems on CNETs pages. Also known as download.com. And if you want to post a comment on a site or login you'll need to activate cookies or let the cookie into CCleaners "to keep". Sometimes you'll need to enable cookies in order to download. Other that that there are no issues.

Also: all deleted cookies will come back the next time you visit the place. If there's something you don't need to worry about it's getting enough cookies, that's for sure...

The easy way to avoid the endless garbage is to use a HOSTS file like the MVPS.org HOSTS file which is always discussed on this forum. And an adblocker for your browser like AdBlock Plus for Firefox.
