WARNING TO VISTA 64X USERS: USE THE NEW SMART SECURITY RELEASE CANDIDATE AT YOUR OWN RISK THE BUG THAT CAN PREVENT YOUR PC FROM ACCESSING THE INTERNET THAT WAS PRESENT IN THE BETA HAS NOT BEEN FIXED. I had tried the beta version of V4 with the disastrous result of not being able to access the internet and having to reinstall windows to re-establish my network and internet connection. I posted in this forum about this: https://www.wilderssecurity.com/showthread.php?p=1371869#post1371869 Several other unfortunate beta users reported similar problems. This was a serious and well-known issue with the beta version. I foolishly assumed that with the Release Candidate's supposed increased level of finality that this basic and fundamental bug would have been addressed. Well I assumed wrong. I had the exact same problem as I did with the beta. My network and internet connection were destroyed. Just as with my last experience this problem could not be repaired with a rollback with system restore and/or a re-installation of my modem and lan drivers. Over the past several months I have installed and tried-out many av and security programs including Kaspersky, Vipre, Avira, Bit Defender, Norton, and Panda. I never had any problems with any of these. Only with ESET. I have several months to go on my Smart Security license and I will not use it. I will never trust ESET again and will never again risk my PC by installing ESET Smart Security. nuf said delete this post/ban me for speaking my mind and trying to prevent others from suffering the experience I have had with the Release Candidade that is Unfit for Release. -- I don't care -- .
