Thank you so much for your help!!
There is only one odd thing I can name, and that is the amount of time it takes for the computer to completely turn on. I highly doubt this is due to whatever virus that was, because this problem has been here for a while.
After the initial startup screen (the one where you press F8), it goes to a black screen with a flashing white underscore in the top left corner. It stays this way for about 15 minutes or so, and then it continues booting without any issues.
Would this be a good thing to ask the OS forum instead?
