What image was drawn in your mind after reading the title? What kind of safety did that question remind you of? Maybe you had a mental picture of murderers! Perhaps you recalled your worn car tires and so on and so forth of all the normal things we tend to think of when we think about our safety.

safety. Sometimes, it could be even more vital to your life and the lives of
the ones you love. Imagine this scenario, a PhD student loses years of effort,
when a hacker compromises his computer and stole and wipe everything, including
his thesis! Or terrorist’s agency gets its hand on valuable information about
the FBI agents, who work on catching those terrorists, and then know all about
them and their families. How about me? I am just a regular student, should I
care about this? Yes you do my friend. Computer viruses and worms are all over
the internet. They could steal your credit card information, Identity or even
spy on you. Spy! How? Whenever I talk with someone about online threats and how
dangerous viruses can be, they seem to have the same old idea: computer viruses
miss with the computer, delete your data and other kind of problems that you
can immediately notice. So, according to them, if your computer is running and
your photos and videos are still in it, that means you are viruses-free! That is
simply
incorrect, some kind of viruses cause a different kind of unnoticed problems.

your bank and credit cards information! The program would work silently on your computer forever.
