When you type a password into any web form, both Internet Explorer and Firefox prompt whether you would like them to remember your password.

If that’s a personal computer, chances are high that you will click Yes and the password is then saved in the web browser.

This “Remember Me” option in web browsers is useful but it actually puts your login credentials at serious risk especially in Firefox.

View stored passwords in Internet Explorer:

Though IE stores your passwords in encrypted form in the Windows Registry database, anyone can easily view your passwords using a free 35kb tool called IE PassView.

View stored passwords in Firefox:

With Firefox, it gets much simpler. The route is Tools -> Options -> Security -> Show Passwords. And there you have all the passwords that you ever asked Firefox to remember for you.

Even that short visit to a nearby coffee vending machine could leak your identity as all it takes is few seconds for anyone to view your secret passwords.

To keep yourself safe, uncheck “Prompt me to save passwords” in Internet Explorer and “Set Master Password” in Firefox.

Deletion of File:

Deletion are of two types:-

there are two ways by which we delete files….

* By pressing Delete Button on the keyboard or by selecting the pose of file or brochure and deleting it.. In this file is traveled to the recycle bin.

* By pressing Shift + Delete together or not allowing the file to pertain in recycle bin.

Here the Windows help menu will tell you that “Deleting an item from the Recycle Bin permanently removes it from your computer.”

So we all are under the misconception that the file is completely deleted. But the answer is “NO” …

Our storage device i.e. hard drive is logically separated into two component parts by the operating system. In one component data is stacked and in the other component its computer address is stacked . When we delete the data then operating system updates a flag in the computer address component of the hard drive which do the operating system acknowledge that the following file is deleted. Now the truth, that data is still there in the hard drive. It is, however, relatively easy to retrieve deleted files with the right software.

Way to Erase File Completely:

The only way to completely erase a file with no trace is to overwrite the data. The operating system will eventually overwrite files that have no pointers in the directory tree structure, so the longer an unpointed file remains in the hard drive the greater the probability that it has been overwritten.
