I just tried to open a small photoshop file and it's taking forever! All of the sudden everything is so slow on my macbook. Is there another virus out now for macs that is slowing my computer down?
Not for Lion and it's updated, however since it's a new machine I suspect there is a problem with the hard drive as that usually appears right away.
Take the machine back and have the drive replaced is the easiest thing you can do, unless you feel up to zero erase and reinstall Lion as thats the method to map off a lot of the bad sectors on the hard drive.

I'm going to buy 8 GB of ram to replace my 4GB and I hope that will make it faster.
You can upgrade it to 16GB of RAM yourself for $200, if you have Apple increase the 4GB to 8GB it's going to cost about $435

Upgrading the RAM yourself is a user replacable part, as long as you don't break anything, your allowed to do it and not violate your warranty/AppleCare. The new RAM is not covered of course.
You'll need the tool kit and a mat to catch fallen screws as they are tiny.
