Troubleshooting
Viruses
— Install an Anti-Virus program and keep the definitions file (the file which tells your program which
viruses to look for) up to date. New computer viruses are discovered daily, and some of them may
seriously harm your computer and cause you to lose data. Anti-Virus programs are commercially
available and the definitions file updates are usually downloadable directly from the internet.
— Be careful when opening e-mail from sources you don’t know. Viruses are often triggered from within
email attachments so take care when opening any attached file. You can configure most Anti-Virus
programs to check all e-mail attachments. Note: You should also beware of files from people you
know as the virus may have infected an address book and been automatically forwarded without the
person’s knowledge.
— Keep a “Bootable CD-ROM/DVD-ROM/USB storage device” (this CD/DVD/USB device provides
basic information which allows you to startup your computer) handy. You may refer to your OS’s
documentation for instructions on how to make one, and many Anti-Virus programs will also provide
such a disk (or at least instructions on how to make one).
Upgrading and Adding New Hardware/Software
— Do not be tempted to make changes to your Windows Registry unless you are very sure of what you
are doing, otherwise you will risk severely damaging your system.
— Don’t open your computer or undertake any repair or upgrade work if you are not comfortable with
what you are doing.
