Adware/viruses

i recently ran a virus scan on my computer. i had tons of infected files. After scanning through, i deleted them. 10 of the files would not delete. Norton said that they were at risk files. I did some research on the files and found out that they were adware. So i downloaded Ad-Aware. it deleted alot of them. Now when i run norton, it says that they are still there.

So i decided to run Trend micro’s online scan. Nothing came up. so then i ran norton security check, nothing came up.

whats going on with my computer?
