Dozens of "debug.log" files appear on my computer every day before I even log on, and now it's acting screwy?

congrats, it's a virus, looks like something you may have gotten in a message, if I were you, I would look for someone who can sell you a new hard drive, and can also install an operating system on your laptop, whatever is on your laptop hard drive, could be contaminated, so unless you have a backup, all that will go. If you don't have a friend who can fix it, it can be expensive like 200-300$
