The website developer couldn't Shanghai my computer with Flash.
Oh dear... you might want to read up on that. Flash is known to be one of the primary ways your computer can be taken over remotely.
Just a few short months ago Adobe had to fix this:
http://www.adobe.com/support/security/advisories/apsa11-01.html
"This vulnerability (CVE-2011-0609) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file ..."
Your computer, along with every single other computer on the planet with Flash installed was vulnerable to being "shanghai'd" for over a week, while everyone just had to wait, finger crossed while Adobe fixed it.
And they've just admitted to yet another critical vulnerability today:
http://www.adobe.com/support/security/bulletins/apsb11-18.html
"This memory corruption vulnerability (CVE-2011-2110) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via malicious Web pages."
Are you still so naive to think a website developer can't take over your computer because of Flash?
