I've had v4 for a while now and my firewall logs have always been totally blank unlike v3 with all the various forms of nonstop cache attacks, hel. Thank goodness that has stopped. Recently, very recently in fact I am now getting bombarded with 3 error messages in my personal firewall in BROWN in and am kind of anxious about it. Blue ink, fine but brown ink has me chewing my fingernails and toenails. Please advise as Googling around and ESET KB has not enlightened me one bit on this and I would appreciate all the input and feedback possible. I'm (as many of you here already know, lol) a worrywort, ignorance of all things technical and the high anxiety type. Sorry about that. 1) Incorrect IP Packet Checksum 2) Incorrect TPC Packet Checksum What should I do? Is it a known bug that is to be fixed? I have Vista 32 bit and use ESET Smart Security Suite v4. All my settings are "default". Thank you all very much in advance and have a great summer!
