First of all sorry for my bad English. I remember using this AV since version 2 some years ago. It was light, fast and detected threats that other AVs didn't so I recommended to everyone I could through forums and such. I'm an advanced user, I use a router perfectly configured with NAT (all ports filtered, ping telnet etc disabled etc), then everything that can connect to the internet is poperly proxied by Eset's Smart Security and browsers are in active mode, everything with it's settings at his maximum even at cost of performance. My XP Sp3 was finely tunned by me disabling all unnecesary services and things like msn netmeeting and other security holes were all fixed making it light fast and secure. I used Firefox with NoScript and Adblock, a nice password policy etc. Also I have common sense so that makes me avoid almost all threats so I've only been infected two times, one when I was just given my first computer (no AV) and then another one some years ago but this does't count since I was sharing my pc with my brother and he was the one who got infected (using Kaspersky at that time). A week ago or so I dowloaded a file zipped, even though it's supposed to be analized while it dowloads, then after it has been copied to the HD and then when I'm going to use it I still manually scanned it (all settings on) and it was ok. Ok no worries then, I've followed a lot of steps only a paranoid user would do so I'm really sure this file is ok (Why do I pay for a license of an antivirus then? I mean what's the point of having one if you can not trust it? I know already what you're going to say about this, but please think carefully about this statement a couple of seconds and you'll see things from another point of view). Ok I extracted it, opened it and then disaster, I see the gui of Eset's Smart Security and Skype crashing and the PC rebooting. Owned. I think about disconnecting the router since I already knew what was happening. When I start I go to the process manager and see something I never saw before (yeah, I even know all the process I'm running) It was called "winupgro.exe" or "winupgro" (Bagle) and I went to the firewall of SS and saw that process opening a lot of connections so I killed it but now I couldn't trust the pc. Skype folder was somewhat transformed in an iconless .exe :S I did a full and complete scan with the latest databases and to my dissapointment it found nothing. Yeah I mean nothing but I knew I was infected lol. I uploaded the file to Virustotal.com that day and almost all the AVs detected the threat, except for Eset's of course. It was detected even by AVs I didn't like before and that really make food for thought, then I used the panda online scanner and quickly detected threats so I didn't even finish it, rebooted and started using Ubuntu since I have it in another partition as backup and now I'm learning Linux lol Some days ago I installed Avast in Linux and mounted the XP partition and scanned and cleaned it but I still can't trust that partition so it'll make me burn my data and then format it, losing precious time. By searching for this virus on the internet I find people with exactly the same one as me from pages that dates months ago last year, for example this one who had probably the same virus as me, though I've not suffered all those things since I terminated the threat quickly the same is reported from experience of various users around the Internet.. December last year: http://www.wilderssecurity.com/showthread.php?t=261656 In that link they say different encriptions of themida should be detected by heuristics. False. So this is my case. An advanced user infected by a virus of MONTHS ago while using Eset's Smart Security I don't even know why did I submitted the file to be inspected by them since I'm not gonna use more this AV (hope others get infected too and make them think about this), so it's time to look for a replacement loosing even more time since bloated cookie cleaners are common nowadays. How convenient... Another thing I didn't like from this AV was something I read time ago in some blogs. It seems Eset is blocking warez websites (even though they're just forums which doesn't host anything, I mean block rapidshare then dammit ) And let me say they said admins of those websites had a strict upload virus=ban policy with his users so yeah, the threat was warez itself. They're also blocking harmless websites with no virus/trojans whatsoever but an ultradangerous 1-and-only page with text. But since that text are Nod's serials that must be really dangerous. Yeah The police of the Internet and morality? No sorry, I don't pay you to block harmless websites, I pay you to block virus in case you've forgotten and you can't even do it well. It seems you have gotten pretty conceited but you have to remember who put you where you are. And that "who" are users who recommended your products to the people when asked what AV to use. But it's alright. Time puts things where they belong and maybe one year maybe two you'll see others taking the place you're in now. Just look how pathetic is Eset's NOD detection, and I don't care about other viruses because the only virus that matters is the one you have under your mouse arrow and this one is already detected by the rest of AVs and at least three months old. It's also funny to think entire enterprises are relying their security to an AV and after seeing this they think they are secure. And yeah Moderator, don't come here and try to say generic statements and such things because they will not do anything to my infected pc. You've failed. Period. By the way I give a chicken if you don't believe something/anything of what I've said. I know it's true and anything of what you say defending this AV will not make me change my opinion about getting infected after having analized (updated/all settings on) a file which contains a virus of three months ago which has already been reported that time long and is detected by the rest of AVs. Period. In case you ask why do I even post it, forums are a place to write down your thoughts and I can see other people have done it already so why can't I? Regards.
