ABSTRACT:
A system and method are provided for protecting a user computer. An incoming e-mail message is initially received at a remote e-mail server over a network. Further, the incoming e-mail message is blocked if a sender address associated therewith is included in a list of predetermined sender addresses corresponding to a user computer. Moreover, the incoming e-mail message is scanned for a virus to determine that the incoming e-mail message is clean if the scanning fails to detect a virus in the incoming e-mail message and to determine that the incoming e-mail message is infected in the scanning detects a virus in the incoming e-mail message. Still yet, the incoming e-mail message is transmitted from the remote e-mail sever to the user computer over the network, if it is not blocked. An attempt is made to clean the infected incoming e-mail message if the scanning detects a virus in the incoming e-mail message to generate a cleaned e-mail message if the attempt to clean is successful. In use, a text message is transmitted to the user computer, indicating results of the scanning.
