There's a bad spam / malware (bad software) attack going on lately on the internet - if you ever get an email from what appears to be a company or organization that encourages you to download software, do not do it.
Follow this link to F-Secure.com (these are the people who write Shaw Secure for Canadian subscribers of Shaw).
"The type of spam runs we saw late last year (Obama and BofA) are starting to pick up again in volume. We've seen Classmates being used as a theme and two days ago it was fake Facebook messages. Today it's back to fake Bank of America certificates."
Note the level of trickery the bad guys are going to - that graphic image looks quite convincing. Imagine your less technical friends and relatives - how would they treat the message? Help them learn what to do.
When in doubt, chuck it out.
