I just cleaned System Care Antivirus out of a computer that was running Eset Security and am curious how it managed to bypass Eset. The owner rang me immediately the program appeared and the only detected threats in the log were: 4/06/2013 10:59:07 AM Real-time file system protection file C:\Users\Penny\AppData\Local\Temp\758F.tmp a variant of Win32/Kryptik.BCQE trojan cleaned by deleting Event occurred on a file modified by the application: C:\Windows\SysWOW64\svchost.exe. 4/06/2013 10:58:54 AM HTTP filter file hxxp://alternativescrucial.org/soft3.exe a variant of Win32/Kryptik.BCQE trojan connection terminated - quarantined Threat was detected upon access to web by the application: C:\Windows\SysWOW64\svchost.exe She told me it just "suddenly appeared" & told her the computer was infected, but a check of her web browsing history shows that she hadn't visited any suspicious sites, only a couple of government websites and the anz banking website (definitely no facebook or other social networking sites). I also went to the same sites on my own computer and got no warnings of infections from Eset. Can anybody explain how something like this gets past Eset Security? Edit: link obfuscated.
