I recently upgraded from ESET SS v3 to v4.2 Beta. My system locks up on the regular v4. My OS is Win XP Pro x64. I've been getting a pop-up error box indicating "Windows - No Disk..." everytime I disconnect a USB device such as a memory stick or floppy. The error box is difficult to dismiss. Anyone have similar problems? I suspect it's an OS side effect from the ESET SS program. When I google the error, I see that there are numerous causes. Some are related to malware. Since I've only experienced this issue since I've upgraded my ESET, I suspect the two are related. Does anyone have any ideas? Regards to all.
