Here's an email, as innocuous as possible, that I adapted from someone else's note to staff:
Please be aware that a security flaw has been found in the Internet Explorer (all versions). This is probably the browser that you may use much of the time. The flaw allows malicious code to steal users passwords, and control their computers.
Avoid using Internet Explorer for online banking at this time. (online banking passwords, are the most desirable target of this exploit)The flaw in Microsoft's Internet Explorer could allow criminals to take control of people's computers and steal their passwords, internet experts say.
Microsoft urged people to be vigilant while it investigated and prepared an emergency patch to resolve it. . .Other browsers, such as Firefox..., Chrome, Safari, are not vulnerable to the flaw Microsoft has identified.
Microsoft is working on a patch to fix the problem, but currently there is no fix. There are many web sites exploiting this flaw.

For your own personal computers (such as those at home), you are encouraged to follow the advice in the news report above and use an alternate browser, like Firefox.
