Please be careful of any email about checking your system for Windows
7 Compatibility.

The scammers steal their marketing text directly from Microsoft, which
offers a legitimate Windows 7 Upgrade Advisor in its Web site.

“Find out if your PC can run Windows 7,” the e-mails read, echoing
Microsoft’s Web page. “This software scans your PC for potential
issues with your hardware, devices, and installed programs, and
recommends what to do before you upgrade.”

Users who try to install the attached, zipped file end up with a
back-door Trojan horse program on their computer. BitDefender
identifies the program as Trojan.Generic.3783603, the same one that’s
being used in a fake Facebook password reset campaign.
