Personally, I would be more worried about picking up a virus from the doorknob...
I think you're confusing viruses and phishing attacks.
A phishing attack involves sending a link to someone that ends up on a web page that cosmetically looks like another (Twitter in this case, but are often banks or other financial based websites). These websites will often ask the user to enter personally identifiable information for the purposes of identity theft. Ask the user to enter credit card details is often common.
Windows Phone users are open to this kind of attack, provided the email has made it through any server based spam detection. If at all possible, people should avoid clicking on links in emails, but should go directly to the relevant web page and log in through the main portal in order to gain access to whatever the email is referring to.
