Lesson 8:
Avoiding Viruses

Big Bad Viruses...

Viruses are software programs developed to wreck havoc on computers.

The level of damage they cause depends on the program.

Some do silly things like popping a message on to your screen, while others can damage your computer, change your programs or wipe out your hard drive.

True viruses can only be transmitted by trading files. If you give your friend an infected file and he opens it, his computer is now infected.
