Can somebody please have a look at my log? I seem to have some sort of redirect thing on my PC. Plus, when I run Spybot something called Zlob.DNSChanger keeps showing up even though I've tried to remove it. I also have problems with AdAware because the scan keeps freezing at 96,917 objects. Lastly, when I try to run AVG it keeps showing up a message that reads "Reading Error on boot sector of disk". The log below will hopefully yield some answers. Thanks guys.
