Actually, this was the exact file name: 452923516fa61b0698feabf31478 Now I'm a massive noob when it comes to these things, but when I was loading up my computer I noticed it was loading EXTREMELY slow today. Slower than usual when its start to desktop speed is usually 20 seconds. Steam was downloading something, and I tried opening up Chrome as well, with Skype too. My computer usually runs all of these fine on startup as well. My computer also ended up freezing and I had to hard shut down my computer. Is this a trojan or a virus? Or is it something I shouldn't have to worry about? Thank you so much!
