Stages virus which first appeared in early June.

In an e-mail sent last week, Logic warned its customers about opening any messages with the attachment title "LIFE-STAGES.TXT.SHS''.

The company advised that the e-mail should be immediately deleted.

Additionally, Logic gave a description of what executing the attachment brought -- a notepad text file depicting the stages of male and female life.

In the background however, the virus is spreading to up to a hundred of a computer's e-mail addresses stored in Microsoft Outlook.

It is understood Logic sends such warnings as a precaution whenever viruses become a threat.
