Are Cookies Harmful?
Only if baked beyond recognition :-) Seriously... they are an essential part of many small and large sites that use them to remember key information for you to make surfing easier. An example would be a shopping site where you place a few items in a shopping cart. Then if you are disconnected from the Net or you leave that site, when you return, a cookie would help the shopping site reload that information so you don't have to search for the items again.

Some Internet users disable cookies and therefore restrain their ability to enjoy many sites. To the best of our knowledge, cookies do not pose a security risk to your PC. If you're looking to tighten up your PCs security... your time would be better spent protecting your inbox with a good quality anti-virus solution and using a firewall for more secure surfing.
