Local Disk

I have a local disk that I didn't create or have access on my computer I just realized that I have it when I went to my computer. I just recently scan my computer and it had scanned up nothing,but when I left my computer on and my idle scan came up with like 6 trogans. I was looking at my security history and I saw a local q but i don't know where it came from and it was accessing the internet from a word.exe. I was wondering if anyone could help with this problem.
