I Uninstalled NOD32 220.127.116.11 with its own Uninstaller. Rebooted, then Installed 18.104.22.168 and now I've got a weird Problem with both Versions. The NOD32 22.214.171.124 Quarantine Tool shows (immediately after the installation) that 1 object is quarantined although there's absolutely nothing in it. I've already tried to uninstall it properly (safe Mode) with the ESETUninstaller 126.96.36.199 + Registry Cleaner but the behavior remains the same and now for both 188.8.131.52 & 184.108.40.206 . I'm using Windows 7 64 Bit SP1 (only one Account and with administrator privileges) Any suggestions about the cause ?
