There is an email being circulated spreading a virus to UofT email clients. The emails contai a .zip fail claiming to contain a PDF document. If someone opens the zip file, their machine becomes infected and it sends versions of itself to people in their address books.
Do NOT open the attachment. If you have, please contact your local IT professional or the Information Commons Help Desk.
You should never open a .zip file sent to you in email unless you are expecting it.
