You should. If you run untrusted code under your account it can do
anything that you are allowed to. This is exactly equivalent to
running an untrusted Linux app. From a security standpoint there is
absolutely no difference between a Windows binary running under Wine
and a Linux binary running natively.

You can use the DOS drive configuration to limit the potential
problems a bug in a Windows app can cause; but it is impossible to
protect against malicious code except by not running it. Wine is not,
and cannot be, a sandbox for running untrusted code.

No, we can't.
