Privacy. Of course, the reason that tops the list is privacy. No one wants their Internet life to become public knowledge. There are too many things on the Internet that can incriminate, even though they are seemingly innocuous. Your browsing histories are stored by default in all browsers. If you haven't deactivated them, then your browser will remember precisely which websites you had visited over the past few days. Not only that, but there are also cookies in your cached files that you need to be wary of. Cookies are temporary Internet files that are saved on the computer so that it becomes easy for you to load the website the next time. These cookies can easily indicate which website you had visited.



Protection. For people who do business on the Internet, password security is of extreme importance. One password in the wrong hands could be devastating. But, the browser does save passwords in several ways. The most common of them is the auto-complete feature that has become omnipresent in all browsers today. Browsers temporarily offer to remember passwords to make logging in easy the next time. This option can be turned off, but it is present by default. And someone could retrieve your password in a matter of minutes.

Safety. Cleaning out the computer is very important for your safety. Your chat transcripts are one of the most important reasons. All significant messengers save your chats, and some of them like Google Talk do it by default. However, these chat transcripts are available only to someone who knows your password. That is certainly all the more reason why you should keep your computer cleaned out. People can also easily reach into your inbox and check up on your communications. If you do business transactions online through banks such as PayPal or MoneyBookers, then you know very well how important it is to keep your passwords protected. If hacked, you will be losing your credit card numbers to other people too.

Separating Online Life from Real Life. It is a fact that most people are quite different in the online life than in their real lives. That is not a problem at all, but problems begin when these lives start to get mixed up. Your spouse may look into your online life and not like what that shows. There have been many marriages broken just because a person is playing out a different life online, which is not a justifiable reason at all. Eraser software is very important if you want to keep you're online and offline lives separate.

Efficiency. All those temporary files stored on your computer can make your computer quite slow. If these files are deleted regularly with programs such as evidencenuker, then there will be a freeing up of the computer's resources, which could make your computer breathe easier and work faster.
