I tried Eset Smart Security 4 about 2 months ago and it works better than the previous versions. The only problem I had was it slowed my computer down considerably. It is possible that I had some things misconfigured. Has there been any improvements in this area since then. Has anyone else notice a decrease performance wise? I guess you have to make sacrifices sometimes but I'm use Eset's small footprint which allows for blazing fast speed.
