Hi I was waiting to ESET to resolve the issue reported on this thread: http://www.wilderssecurity.com/showthread.php?t=254272 But, it's been two weeks since the error was reported for the first time, and ESET still can't find the error. So, I must post an idea for a posible cause: This error ocurrs under the following scenarios: - Windows 7 (any edition, any language, x86 or x64) installed - NOD32 or ESS 4.0.467 (any language, x86 or x64) - Microsoft KB Update released on the week of October 12 installed This update was optional on the first days from being released. After that, it became mandatory. http://support.microsoft.com/?kbid=974431 This could be the problem. Please verify it. Cheers from Santiago, Chile. Jolo.
