Cookies might sound like a delicious and sweet treat however, when talking about your computer we are referring to the pieces of data collected from your web session that get stored in your browser. Every time you revisit the website, the browser then sends the cookie back to the website with all the stored data from the earlier visit.

For this reason, cookies can be helpful and can appear to be sweet making browsing a breeze, pulling up your usernames and passwords and even showing you ads for things you previously searched for. On the flip side these cookies can be stored for years causing your browser to move slower and these targeted ads can start to become annoying.

However, these cookies travel across the internet bouncing from server to server and can easily be intercepted falling into the hands of a hacker. While cookies are mostly used by ad services, they also store information from banking sites as well as other personal information you may have entered on shopping sites like your address or other contact details. Therefore, cyber security experts recommend clearing your cookies from your browser frequently and especially whenentering personal and sensitive information to websites.

These are the basic steps to clearing your cookies.

While cookies can be used to your advantage they can also be used to the advantage of hackers leaving you wondering who stole the cookie from the cookie jar, and by the time you figure it out the damage could be done.
