Dee, and Janet - I simply downloaded the latest update to chrome. It's perfectly safe to do this from the Chrome website, if you go there yourself and not through an email link. The Chrome release website shows there is indeed an "exploit" that the update addresses, but it doesn't give any real details: https://chromereleases.googleblog.co...esktop_25.html
It DOES say it's a "security fix" though.
An easy way to update Chrome safely, is to go to Help|About within the Chrome browser. That should automatically download the update if there is one.
Thank you, Janet - for letting us know about this.
