Hi All, I had a quick question about Norton Anti Virus and whether it can cause a machine (in this case a new MBP) to lock up/freeze when booting into OS X. This is my friends machine (she got it from our work so our IT department always messes with the machines first and install all this antivirus crap when there is no need). Sometimes the machine boots up but it will take about 30 minutes to do so, but most of the time it will not do anything. I am not sure if this is a Norton issue or maybe just the HD. Any help would be greatly appreciated. Cheers! P.S. I already tried resetting the PRAM and SMC. I also ran fsck (everything normal).
