Something hijacked my email signature yesterday in the University’s Groupwise system. It changed my signature text to a spam message and toggled the signature to always be on (which is why I noticed after sending out only three emails today because “WTF, why am I not being prompted to say Y/N to signature?” made me look in options).
Hmmm. I ran Spybot and HijackThis with no evident changes to the registry or suspect processes. So I alerted Computer Services but am still rather mystified as to how this happened. Hmmm!
