Hi , I have recently installed Nod 32.I have a 1.1 gz ,256 Ram ,XP Pro laptop.Everything works ok but for regular 1 second lockups. I read the previous thread about compressed files that could be the cause.I wasn't too keen on downloading the upx program after reading the forum there.Security problem. If i quit Amon there is no freeze,so i know this program is having difficulties. What files should be put in the ignore list,would this help? Secondly during a full system scan pagefile.sys is the only file that can't be scanned.Is this the same for other users ??
