My Freeze Toolbar spyware?

[JohnRoss]

Had a bit of a worry last night as the computer froze when I opened an email from someone in the UK that I get a lot of amusing/ jokey forwarded emails from. Having restarted to get control I ran a Microsoft Security Essentials full scan which found nothing. However Spybot found something called My Freeze Toolbar and the title in the email was Something for you. Having allowed Spybot to delete the item all is well and further scans showed nothing. There seems to be a legitimate site called http://www.freeze.com/ but various computer forums have described it as malware/spyware. Of course it could just be coincidence that the computer froze at the time of opening the email. Has anyone else had this and if so what does it signify?............................JR
