Team AOL has created a free service that automatically scans every email attachment you send or receive for viruses, worms and Trojan horses. We scan all email no matter what version of AOL software or computer you're using. Despite this email scanning, someone using your computer could still accidentally infect it with a virus.

At this time, a virus cannot infect your computer when you simply read an email or instant message. If an infected file is attached to an email message, you must download and run the attached file on your computer for a virus to infect it. For an instant message to infect your computer, you must both accept the file transfer and then run the file. This is why it’s very important to be cautious of unsolicited files sent by someone you don’t know. The safest policy is to never download files sent to you by strangers.
