I'm not clear on what you are telling us. Did you get an email marked spam that looks like it came form Craigslist?
Did that email contain a link they wanted you to click to verify your account?
The link looks like it has "oldenburg-tourist" as part of it. Is that anything to do with your Craigslist account? If not, it's most likely a spam email trying to get you to give them your Craigslist log in info.
Have you tried just going straight to Craigslist as you normally do to see if your account is as you left it?
I would guess Trend Micro is trying to protect you from a spammed phishing email. If there really is a problem at your Craigslist account, there may be a notice you'll see when you try to log in telling you to find the verifying email to click a link.
