File sharing and sending and receiving data

When sharing files with friends and colleagues using the internet, take precautions to ensure files are not infected.

When sharing files with friends and colleagues using the internet, email, CDs or memory sticks, activate your security software (firewall and anti-virus) and scan files to make sure they are not infected.

Do not assume that because a file was sent or given to you by someone you know, it is safe. Plugging in a removable device can infect your computer if it is not protected.
