I've got a strange failure in my ACER Aspire 3002 WLMi laptop. When I tried to scan the C:\ disk, almost all av:s were able to shut down that laptop, when their scans reached the C:\Windows\system32 folder. I've tried to scan my C:\ with AntiVir PE Classic 7, BitDefender 9.5 Std, DrWeb 4.33.2 and F-Prot 3.16f, but my laptop shuts down all the time when those apps reached that C:\Windows\system32 folder. Only F-Prot reported a suspicious boot sector infection. All these happened after that I made a new WinXP Home Fin installation by ACER eManager and before that too. Only McAfee VSE 8.0i, with the newest 5100 engine, NOD32 and KAV 6 were able to made that full scan. I've reported that problem to DrWeb with the full scan report, but no success ever. What's going on? Best regards, Firefighter!
