I got this in a newsletter from cyberinsecure -

"Windows 7 Default UAC Bypassed By 8 Out Of 10 Malware Samples"
{that means 8 malware infected the machine}

[On October 22nd, researchers settled in at SophosLabs and loaded a full release copy of Windows 7 on a clean machine. They configured it to follow the system defaults for User Account Control (UAC) and did not load any anti-virus software. They grabbed the next 10 unique samples that arrived in the SophosLabs feed to see how well the newer, more secure version of Windows and UAC held up. Unfortunately, despite Microsoft’s claims, Windows 7 disappointed just like earlier versions of Windows. The good news is that, of the freshest 10 samples that arrived, 2 would not operate correctly under Windows 7.]
