I started getting intermittent bluescreens after I installed this as part of the Norton SystemWorks 2006. Yesterday, my computer went into a bluescreen death spiral and would not boot up, even in safe mode, without bluescreening out. Today, I took it to the computer doctor, who removed GoBack and my computer is once again behaving perfectly. Do NOT use this product.
