Vista x64 SP2 Eset Business 4.0.474.0 IE7 Firefox 3.5.6 I have been fighting with this for a really long time and I'm completely frustrated with it. I have two workstations running Vista x64 SP2. On one of them, most, but not all web downloads of zip files will hang at "Estimated time left: 1 second" for IE7 or "a few seconds remaining" for Firefox 3.5.x (currently 3.5.6). If I leave them alone, sometimes they will finish in 30 minutes to one hour. During this time, my CPU shows ekrn.exe is using 40-60% of CPU time (this on a box with dual Opteron 170 processors). If I disable eset nod32 _before_ I start the download, everything is fine. My 10 licenses are up for renewal in Feb. If I can't get this problem solved by then, I'll be looking for different malware protection.
