The other day I was browsing the Internet at a browsing center that I did not visit frequently. Side by side I was using the computer for resizing the pictures (for blog postings), which I got from my Pen drive (USB Flash Drive) that I had inserted on to that computer. As I resized and saved the first picture with the help of Microsoft Picture Manager, an alert message was displayed as, ‘Contact Administrator,’ without saving it! I stopped all the work on the computer and quit. But later on, when I used the pen drive on another computer that I used to, I found all my files missing, and gone forever! When I saved a new Word document it was saved in another folder instead of saving in the usual (but now missing) folder. The problem was then found out to be in my pen drive – that has been now infected with computer virus transported from the previously used computer. By using Antivirus softwares most of the lost files were retrieved back. Now I heave a sigh of relief.
So, be cautious in using a computer that you are not used to and check its protected status before using it. Or, use only that computer that is well known to have protection against computer viruses.
