The best way to avoid computer viruses is to install an anti-virus program. For Windows computers you can obtain a free anti-virus program from Grisoft: AVG Free Edition
Be sure to keep your anti-virus program up to date by using the built-in update feature, or by visiting the website of the manufacturer. If you choose to purchase an anti-virus program, be sure to renew any subscription charge or your anti-virus will no longer work
(usually every 1 to 2 years).
In addition to your anti-virus program, we automatically scan for and reject email containing a virus or suspicious file type.
