Hi guys I've just switched from Nod32 v.3 to v.4. When I was using v.3, there was no problem with xp boot. However, having installed v.4 and reboot the computer, xp gets stuck at windows logo screen while booting and that little progress animation thing keeps moving from left to right and nothing happens. It is clearly related to v.4 but cannot figure out why. Did any of you have the same problem and how did you resolve it? Any help appreciated.
