Can a User Accept a Trojan Horse? Yes and No, It’s just like email attachments.

Before a Skype user accepts a file transfer from another Skype user, the recipient should

have up-to-date anti-virus software installed and configured to scan all incoming files, even

from people who they know.

Skype’s File Transfer feature gives Skype end users a convenient, secure channel for

sharing photographs, documents and other electronic files with other people on the Skype

network. Unfortunately, along with any newfound ability to share data comes the risk of

inadvertently accepting a malicious file that contains a virus, Trojan horse, or spyware.

The good news is that Skype’s File Transfer feature only works among instances of the

Skype client. The Skype client enables a Skype user to request that another Skype user

accept a file, which (upon acceptance) will be downloaded to the recipient’s computer. Put

simply, file transfers can only take place and with the explicit consent of each recipient.

As a result, in precisely the same way that every end user must be cautious when they

accept an email attachment or download a file from the Internet, they will reduce the risk

of infecting their computer if they think before they accept a file transfer, especially from

people who they don’t know.

Refer to the section above, entitled “Security & File Transfers” for more detailed

information.
