Mbs Account locking my Computer for Ten minutes every time I turn it on, how can I delete off my Harddrive?

Try four things, download and update AVG Antivirus run it in the normal manner and then run it in safe mode also. Do the same with Spy-bot Search & Destroy, Ad-Aware, and Windows Defender. These are all free programs and do a very good job of removing the "nasties". If they work, do a defrag after you are done with your scans.
