I can't tell if it's a particular extension that I tried to synch from my other machine, the chrome application itself, or just a false positive. I've run a full scan on the another machine that Chrome is synched with and nothing was detected.

Should I be worried? What can I do to get rid of it?

Answer: 
As a workaround for now, the [current Chrome Beta](http://www.google.com/landing/chrome/beta/) doesn't trip the MSE stuff.

**UPDATE:** Microsoft confirms it's a false positive and releases a fix, [read about it](http://www.zdnet.com/blog/bott/users-report-microsoft-security-essentials-removes-google-chrome/4006).
I do believe Chrome launches its extensions in a secured environment within itself.

I would disable/delete all your extensions and scan the same file. If it is not detected as the same file, then an extension is the cause, and could be a real threat.

Of course MSE does use behavioral detection, so the chances of it beng a false positive is very high, I would simply use a website that uses several scanners to verify the file.

PWS:Win32/Zbot is also a generic threat.
