Hello, Many users on this forum know that I'm a fan of NOD32 But I'm angry again with ESET for the following reasons: 1) First, I sent about 50 samples undettected by NOD to ESET and ESET added only about 10. I consider this time very slow including if the sample isn't ITW. 2) I've a "agreement" with ESET viruses analyzers. Because I send a lot of sample, they only reply me: Packed X confirmed, Thank you. I'm agree however many times I sent a sample for example on tuesday and they confirm my e-mail recently the friday so I can' send more sample until I know that ESET has received that. 2) I know that ESET share samples, but it's a little!. For example, Symantec was the only in receive Rugrat sample and Symantec sent this sample to other companies like KL, Network Associates, etc because those have agreements. Why NOD not? Recently, KAV was the only in receive first mobile phone virus and share it with Symantec, etc and not ESET because ESET hasn't agreement with most AV companies. Many times, ESET add malware that are spreading more slow than others AV because ESET doesn't have such agreement with others AV. How about Korgo?, Netsup...? 3) ESET doesn't find viruses in Internet. Many viruses that I sent to ESET were downloaded from VX sites. If I sent the sample, they add detection very slow. I sent the link directly to ESET labs and they doesn't try to find malware undettected by NOD. This site contain yet more sample undettected by NOD. I need to collect those, however they can't do that. Well, it's all. Sorry for critic, but we need that ESET fix some important details like those. Sorry, but without heuristic, NOD is a bad AV. I'm very very happy in send viruses to ESET, if they add sample more quickly or they confirm all my mail, I'll be happy searching and searching hardly samples to ESET, however if they doesn't reply me or add samples too slow, I feel frustrated. Thanks.
