In your example, this is the best way I could describe what they mean:
corresponding: the message that is displayed is a result of the dangerous link. It is somehow tied/related to the link, but this use of corresponding places no value on the content of the message.
as such: the message being displayed is somehow telling the reader that the link is dangerous. This sentence sounds the most awkward of the three. "As such" is usually closer in usage to "therefore".
accordingly: this is similar to corresponding, but implies more value. It shows that the message will be in agreement with the "value" placed on the dangerous link. That is, that the message will likely give a warning.
For an example to better illustrate the nuance between accordingly and corresponding, consider the following scenario:
Link: Get free money here
You click the link, and the corresponding message from the link comes up as "Enter your bank information here to receive your money". However, you have an ad-blocker, and it recognizes the dangerous link and displays the following message accordingly: "Do not trust this link".
