Please help. I've got a Dell Inspiron 1545 with Windows 7 on it. Almost everytime I use it settings and things have been changed even though it stays locked in my office which is in my garage and noone but myself has a key. Also, I'm often redirected when online yet I've run McAfee, Advanced Systems Care 5 as well as Microsofts latest antimalware program and all that is ever found are cookies. I've attached a Hijackthis log in hopes that someone could help me with this. Please advise. Thank you.
