Some users of Microsoft Windows might have gotten or will get soon an e-mail asking them to download an update. Don’t do it. It’s a virus. One clue is the strange capitalization typos in the message. Corporation is spelled out but not capitalized and “thankyou” is run-on.
It contains one of the “Backdoor” viruses that’s been making the rounds in the last few years, according to F-Secure, a computer security firm.
A sample of the e-mail can be found at the blog of F-Secure, a computer security firm.
