Hmm, you followed a link. Very probably a scam. What you downloaded probably wasn't Flash at all, but a big bunch of malware.
For Flash go to http://get.adobe.com/flash but you may have a MUCH bigger problem.
Thank you for the warning! I thought I'd be safe as both myself and my college got this link from the Adobe website itself.
I'll try that one,
I just checked the link that you gave me and its the same link I followed to try and get it previously but it still doesnt work, do you know why this might be?
22.214.171.124 is the most recent version, released earlier today. You most likely need to enable Flash for the particular site, or the sites Flash detection isn't coded correctly.
