I changed my cookies on my computer from medium block to medium high
block, since I found a lot of adware.  Will this change the way my
computer works as far as my using it?  Will it keep my from being able
to do anything?

Hi,

It will block internet cookies while you are surfing the web. This
means that information you entered (like passwords, usernames and
others) on the web will not be stored in a cookie. This means that you
will have to logon each time you visit a webpage (like hotmail, Google
Answers). This will not change the way your computer works, it will
just not save any personal information on your disk while surfing the
web.
When you want to remove adware, or malicious cookies, you should use
Ad-aware. Just deleting your cookies, or setting high block for
cookies, will NOT remove AD-ware.

If you have any more questions, feel free to ask,
Hope this helps you out,
