virus help needed

without going out on the web I ran quick scan 7 times. It said it resolved all threats and that I needed to restart each time.

ran it a 8th time and it found 11 threats (low )   and trojan.kotvarlgm2     it found all of these exactly each and every time, says it fixed them but they reappear, I have run the long version twice and the other norton utilities but they still show up.

need help
