SA- Ashampoo site has browser exploit?

I recently tried to go to the Ashampoo site but McAfee's Site Advisor would not allow access. There was a warning that said-

"Browser exploit:
Breached browser security

When we browsed this site, it made unauthorized changes to our test PC."

Is this a false positive with SA? Have there been other security programs with similar warnings?

McAfee defines an exploit as follows-
"Exploits are rare but extremely dangerous security threats caused by a Web site "exploiting" a browser's security vulnerability. The exploit can cause the user's computer to receive programming code which can cause adware infections, keystroke spying, and other malicious actions which can leave a computer essentially unusable."
