I have not been able to receive Microsoft updates since the beginning of April. They fail. Today I attempted to install XP sp3 and it failed. Checking with Microsoft support, it was suggested that the problem could either be my FW or AV not permitting changes. I first shut down my FW, and tried again, but that wasn't it. I then disabled my NOD32 v3.650, and tried to do the update and it was successful. Checking when I upgraded Nod to v3.650, I discovered it was April 4th, exactly when the Microsoft updates started failing. What do I have to disable or what setting do I have to change in NOD to correct this? Thanks.
