Think my computer may have been hacked?

This could be me just being paranoid but the other day I was browsing the deep web with one of my friends, who convinced me it would be cool to see the "hidden wiki". I said fine, not thinking much of it. We didn't go on any weird CP websites. Just looked at the hidden wiki and a website that sold IDs (didn't buy any, of course). I looked at the top left of the scree and realized the no script was set to "Allow all scripts". I freaked out and then I closed it. Yesterday I was looking at my email and found that it had been signed into in several different places. This scared me. I now have read that the deep web contains viruses, trojans, and other harmful things. So I did a set of 5 commands another forum poster wrote to see if anything is fishy.

I don't see anything too weird... but I'm not savvy with this. I know this seems really trivial but it would mean a lot if someone could check this out. I appreciate it in advance.

Also, If I were to be extra careful, sould backing up my stuff to an external hard drive and reformatting my disk to factory settings put me in the clear? Thank you! I really appreciate any feedback 🙂
