Google Chrome targeted by Malware

Interesting piece by Ed Bott: Malware authors target Google Chrome (on Windows).

Sounds similar to these kinds of fake Windows anti-virus scans which you see around the place, and try to convince you to click and download an executable which will supposedly clean up your PC:

This type of thing reinforces the fact that no browser/platform is safe from malware, and that it’s important not to regularly run your account with Admin privileges on your PC.

Personally I reckon it wouldn’t hurt to have a setting in Windows (and other operating systems) that prevents running executables from any directory where the current (non-Admin user) has write-permissions, eg only letting them run programs that have been installed by an Administrator.

Does any OS offer something like that at the moment?
