  10. 10. What are the signs of viruses  Almost anything odd a computer may do,can blamed on a computer "virus" especially if no other explanation can readily be found.  A computer virus can cause unusual screen displays, or messages - but most don't do that.

What to do when you find viruses  Make sure that it is virus and what virus it is.It is important to know what kind of virus you are dealing with.Companies that make anti-virus programs know what different viruses do and you can go to their web pages and read about the virus.  In some cases it is not good to start your computer from hard disk, because the virus may active and then do some harm.
  13. 13.  The best way to protect your computer is to use updated anti-virus program.  One can protect the computer against boot sector viruses by setting the BIOS to start from a hard disk rather than from a floppy disk.  Write protection is a good way to prohibit against viruses.
