Check For Viruses

What Are Viruses?

Computer viruses are malicious programs designed to cause annoyance and even damage to computer data. They spread by infecting files and by automatically sending e-mails to everyone in your address book.

There are new virus threats everyday. It is essential to take steps to protect your PC.

What Can I Do About Them?

If you suspect you have a virus on your computer, or if you just want to keep your computer safe from the threat of viruses, there are several virus-detection programs which will scan your system and let you know if any malicious programs have been found.

There are many commercial and free anti-virus programs available on the Web, all with different features and levels of security. This tutorial uses AVG Anti-Virus.

AVG Test Center

You can now see the AVG Test Center window.

Here you can see your Security Status, and choose to perform scans on your whole computer or selected areas only.

When you run a complete scan, it may take a while depending on the size of your hard drive. It will scan your system for any viruses and if it finds any, it will pop up a window to inform you what action it has taken.

If possible the program will try to 'heal' any infected files, or if it is unable to clean these files it may move them to its Virus Vault, where the infected files are kept in a state where they will not be able to harm your computer, but can be retrieved later if necessary.

The AVG Anti-Virus program contains several tools which continuously monitor your system, but it is recommended that you run a complete scan of your computer regularly, at least once a month to check your computer for any infected files.

If you do not want to run a scan now, just click the Close (X) button at the top-right of the AVG window. This does not in fact stop the AVG program running, it just closes the windows so you can get on with using your PC.

Using The AVG Icon

You can tell if AVG is running as a small coloured icon will be displayed on your taskbar.

If you right-click the AVG taskbar icon you can restore the Control Center and Test Center windows. You can also perform a manual Check For Updates from this menu.

AVG will quietly monitor your PC and check for viruses while you continue using your PC. It will start automatically when you first turn on your PC and check for any updates when you connect to the Internet.

If you need to stop AVG running for any reason, right-click the taskbar icon and choose Quit AVG Control Center.

To start AVG, click the Start menu then All Programs. Click AVG Free Edition and choose AVG Control Center.
