So, your “friend” send you an email with a link and says, “check this out!”

Is it safe to clink on that link?  Check it first.

Or, you find your self at a suspect web site, and your computer behaves strangely?  

Check that link for exploits.

Any web address (link, URL) can be checked for exploits by using the Link Scanner at Exploit Prevention Labs.

Thousands of users worldwide have already had their login names and passwords and online banking credentials stolen by this exploit. 

It arrives in the form of an email greeting card from a secret admirer.

Attempting to read the ”greeting card” redirects the user momentarily to a web site that attempts to install key logger software, hidden by a rootkit, then it displays the greeting card. 

I you have installed the MS06-014 patch, released in May, you are not vulnerable to this exploit.

This is an example of why keeping up to date with Microsoft Updates is critical to safe computing.
