How to I undo what was done after clicking on a link from a spammed email?

Question

Hello...
I am usually Never one to click on any suspicious emails, let alone links within the emails, but I recieved an email from my Uncle that looked slightly suspicious, but I let myself click on the link within it. It turned out to be a spammed email with a BS link from "msnbc" reharding jobs. What happened when I clicked that spammed link, and what can I do to undo what was done? I am terrified that I unintentionally installed something on my Mac Air through clicking on this link. What do I need to do to erase what was do, and how to I find out what was done? Thank you very much for your help. I greatly appreciate any advice.

Without knowing what webpage the link opened and what you did after you opened it, it is impossible to be 100% certain of anything that may have resulted from that. An email itself cannot install anything. If the webpage did not result in any unusual activity, and you did not deliberately install or supply any personal information then you have no cause for concern.
"Unusual activity" would include symptoms such as a webpage you cannot close or navigate away from, and that would be a mere nuisance that is easily solved. If Safari or the browser you used is behaving normally then rest easy.
Most of these spam emails do nothing but bombard you with ads or attempt to install a browser "toolbar" that does the same. Malicious emails include phishing scams and most of them are laughable (but they are getting better). Others carry Windows malware that cannot affect your Mac.
To edit your profile click on your name at the top of this page (where it says Welcome, saratee14), scroll down to the heading My Products, click edit, and on the page that follows select your version of OS X from the dropdown menu. The only reason I questioned this was to confirm you have been updating OS X.
