Hello; I am currently using Bit Defender 2008 for my AV software. When it auto updates, it locks up my PC for about 30 seconds. Also I now think it is making my machine freeze and hang when using other software. I am interested in purchasing NOD32 version 3.0. Does the auto update slow the PC down or lock it up. I have never heard of ESET before so I am looking for user thoughts and pros and cons. Thanks very much for your help!
