Leading antiviruses / scanners (Kaspersky, Bitdefender, AVG, Avira, SuperAntiSpyware, MalwareBytes, ... etc. from 2k10 USB drive), AVZ cannot detect a virus in Windows 7 x64 installation that manifests itself in preventing from running Antivirus, msconfig, Office, etc. (File not found - immediately or after a small delay), but many simple programs still can start. Scanning does not give any related results.
Maybe exist some kinds of virus scanners over the world - ones that can be installed to offline Windows installation, or ones that allow to launch infected Windows in an emulator, any other for the purpose?
Are there new tools allowing to catch such an infection in the world of crooked antiviruses justifying its stupidity by rebranding in terms like rootkits / super-rootkits?
