Not sure if this a false alert. Just got a new laptop, installed Eset SS right away. Gateway running vista64. Every couple of days I get a little pop-up from NOD about a possible unknown boot virus, could not clean. Here is what shows in the log file: 9/3/2008 5:15:04 AM Startup scanner boot sector MBR sector of the 0. physical disk probably unknown TSR.BOOT virus unable to clean Nothing is ever detected in the in-depth scans. Any suggestions?
