What is antivirus software?
Antivirus software is a program that either comes installed on your computer
or that you purchase and install yourself. It helps protect your computer
against most viruses, worms, Trojan horses, and other unwanted invaders that can
make your computer "sick." Viruses, worms, and the like often perform malicious
acts, such as deleting files, accessing personal data, or using your computer to
attack other computers.Why should I use antivirus software?
You can help keep your computer healthy by using antivirus software. Remember
to update your antivirus software regularly. These updates are generally
available through a subscription from your antivirus vendor.
How do I tell if I already have antivirus software on my computer?
Check the Programs list on the Start menu and look for an antivirus program.
Many major computer manufacturers include at least a trial version of a popular
antivirus software package, such as McAfee or Symantec. But just because the
software is installed, doesn't mean it's "turned on," or being updated
regularly.
How do I keep my antivirus software up to date?
Out-of-date antivirus software means ineffective antivirus software.
Antivirus software relies on regular updates to help protect against the latest
threats. If you aren't subscribed to these updates, your computer may be
vulnerable to attacks by malicious software. Here are some tips for making sure
your antivirus software stays current:
- Purchase an annual subscription from your antivirus software company to make
sure your antivirus software stays current and effective. If you have purchased
a subscription, most antivirus software will update itself when you are
connected to the Internet.
- To ensure your software is up to date, open your antivirus program from the
Start menu or the taskbar notification area and look for update status. If you
still aren't sure if your antivirus software is up to date, contact your
antivirus software provider.
