I am not sure if it is just ESS v 3.0.657 or this version with XP SP3 but there are a number of incompatible issues with trying to get programs to run. I have already contacted Eset direct and if it keeps going, according to their advice, I will have many programs excluded from real time scanning or most of the anitspyware functions will have to be turned off. Several of my programs will not run unless I disable antivirus and antispyware. The latest is Windows Media Player 11. It won't play dvds and just hangs until ESS antivirus/antispyware is disabled. Is Eset going to fix this problem as there is no point in having ESS on my system if I have to have half the ESS program disabled to run other programs.
