PC Help Needed

I found an old 11 year old computer, but it is very laggy, and I can not find the delete all data option despite reading the manual, I never used it as after all this time because of how slow it was, last time I tried to use it a couple months ago I got porn flashed on my screen upon opening Internet Explorer, haven't touched it since, but I want to try again, I want to see what it can do. Any help is appreciated!
