So about a few weeks ago, I thought I had some kind of virus/trojan on my mac because my e-mail got hacked into. I called apple and they sent me to the pccareexperts.com. These people used logmein to access my computer and typed in some commands into Terminal, trying to tell me I had foreign IP addresses try to hack into my computer. Well I got really suspicious and decided to end the logmein access, but I'm afraid of what they had typed into Terminal on my mac. I haven't noticed any suspicious activity, but I'm a bit paranoid about them doing something to my computer. Would it be a good idea to do a clean install and try to re-install all of my apps. I don't have a previous back-up before this incident.
I'm not calling you a hypocrite or a liar, but Apple wouldn't send you to this "pccareexperts.com" that you speak of. If your email account was compromised, it'd most likely be the server that is hosting your account, not your actual computer. OS X is based on UNIX. It just can't become infected by malware that was written for Windows. Yes, the infected file can sit on your hard drive, but it can't execute. If you don't believe me, and want to believe this suspicious (IMO) story, then clean install your Mac.
But, what if they did something to the EFI of your machine? Oops! Guess it's time to buy a new Mac, then. There isn't a way to restore your EFI, as far as I know.
I'm not saying your story is fake, but it's pretty suspicious. Plus, this "pccareexperts.com" is a dead site. I know that sites that host malware are usually up for a very small amount of time, and they then die.
