No so fast;  if you received an email that looks like it's from a friend of yours - sharing a document via Google Docs, you may want to investigate before you click into it.  A phishing scam is making its rounds through the web using what looks like legitimate contacts of yours.

According to sources, recipients receive an email from a familiar sender in their inbox, looking to share a document via the popular cloud-based server.  Once you open the document, Google Docs appears to ask you for further information - the same sort of details it would normally ask for.  Once you enter permission details, the suspect code then accesses your contacts to further propagate the scam.

If you receive a suspected email from Google Docs, experts recommend deleting it right away.
