I have a major problem with Eset Smart Security 4 ver 188.8.131.52. Signature Database 5800 last update 19 Jan 2011. Running on Window 7 Ultimate 64 Bit. Since the last update it started giving me an error saying it could not create temporary file during the signature update. I downlaoded the 4.2.67 release and tried to install that over the top of my current version and I get the following error Error getting file security C:\ProgramData\Eset\Eset Smart Security\logs\escan\GetLastError 5 (I am logged in as Admin) The install then rolls back and says it's failed and I have to restart Windows. I then thought maybe I should try uninstalling the current version first. I looked in the Control Panel \ Programs and features to try and uninstall but it doesn't appear in the list. I have the Uninstall option in the All Programs\ Eset menu but when I try and run that it says that "this action is only valid for programs that are currently installed". My eset still appears to be running in the system tray and I can access the GUI and run a scan etc... I am also getting an error when I start my Thunderbird Email client. It say anti spam module cannot initialise. So, I am now stuck, I can't uninstall the current version which is not working correctly and I cannot install the newer version as it gives the error I detailed above. Anyone able to help please?
