Bitdefender's CEO and founder, is a visionary entrepreneur who has worked in the high-tech security business for the past 20 years. Right after the “fall” of the soviet block in 1990, with his wife Mariuca, he created Softwin, one of the first ever Romanian private software companies and the mother company of Bitdefender.

A user of a Windows 7 Professional system (64-bit version) sent me a screen shot she had taken of a BitDefenderThreat Scanner window that had popped up on her system Friday morning. Shehad been seeing the message periodically in the past. She had alsoinformed me on January 4, 2016, i.e., eleven days prior to the mostrecent incident, that she had received a similar message.

BitDefender Threat Scanner

You are strongly encouraged to send the fileto the developers of the application for further investigation of theerror.

I thought I had installed BitDefender Antivirus Free Edition quite some time ago when trying to resolve a problem with malware on the system. But when I looked for a BitDefender directory under C:Program Files and C:Program Files (x86), I did not see one, nor did I see any directory associated with it underC:.

From a command prompt for the user's account, I scanned the registry for any references to BitDefender under HKEY Current User (HKCU), but saw none.

Note: The /f and /s options to the reg query command perform the following functions:

I also opened a command prompt with administrator privileges by right-clickng on Command Prompt and choosing 'Run asadministrator' and performed a similar check for HKEY Local Machine (HKLM),but found nothing.

I also opened the Control Panel and looked for BitDefender under'Uninstall a program', but it was not listed there. Nor did I see anyscheduled tasks for it when I ran a schtasks /query command.

I first ran the above command from a command prompt for the user's accountand then for a command prompt where I chose to open it with 'Run as administrator', but in neither case was anything found containing 'BitDefender'. I did see the dump file was placed in C:WindowsTemp at 3:03 AM local time on Friday morning.

Note: to see the file I had to issue the command from a command promptopended with 'run as administrator'.

So I then tried the Windows SysinternalsAutoruns for Windows utility, which I've found very useful for locatingthe starting point for programs in the past.

This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and when you start various built-in Windows applications like Internet Explorer, Explorer and media players. These programs and drivers include ones in your startup folder, Run, RunOnce, and other Registry keys. Autoruns reports Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond other autostart utilities.

The program, which was developed by Mark Russinovich, who foundedWinternals Software LP with Bryce Cogswell, a company subsequently acquiredby Microsoft, is free. There are many other very useful free Sysinternals utilities now available from Microsoft.

When I ran autoruns, I clicked on File then choseFind and searched for BitDefender.

It found a 'Trufos Mini-Filter Driver'.

trufos.sys	Size: 441 K
Trufos Mini-Filter Driver	Time: 10/11/2014 4:01 AM
BitDefender S.R.L.	Version: 2.4.851.21851

When I checked the date on the trufos.sys file, it had a date of about a year ago, i.e., January 22, 2015.

But the driver was apparently installed on the system on July 5, 2015,since when I searched through the System event log for Trufos, I saw a log entry with an Event ID of 7045 dated 7/5/2015 10:45:15 PM referencing Trufos.sys. I did not find any other entries referencing 'Trufos',though log entries went back until March 5, 2015.

A service was installed in the system

Service Name: Trufos
Service File Name: system32DRIVERSTrufos.sys
Service Type: kernel mode driver
Service Start Type: demand start
Service Account:

Note: you can search the System event log by clicking on the Startbutton, selecting Control Panel, System and Security, andView event logs under Administrative Tools. Then underWindows Logs click on System to select the Systemevent log. You can then click on Action and select Find. Iput Trufos in the Find what field.

I also saw the driver when I issued a driverquery command and piped the output into the findstr command.

Note: with the findstr command, you can searchfor multiple strings by separating them with a space. By searching on 'Module',', and 'Trufos', I could get the two header lines and the line for Trufos,but ignore all the other output from the driverquery command.

I attempted to uncheck the check box to the left of the Trufos entry in autoruns to keep the driver from being loaded when the system boots,but saw the message 'Error changing item state: Access is denied.'

But when I clicked on the Run as Administrator button and provideda userid and password for an administrator account for the system, thecommand appeared to complete successfully. When I searched again, 'BitDefender'wasn't found, but when I clicked on the top entry in the autorunswindow and then searched again, it was found again with the check box stillchecked. It likely wasn't found initially because autoruns was starting the new search from where it was previously; clicking on the top entryin its window caused it to search downwards from the top again. I was able to click on the check box this time and it changed to unchecked.

Since searching downwards from that point did not find any further referencesto BitDefender, I believe that the trufos.sys driver was the cause of theBitDefender Threat Scanner error message the user saw.

When I reissued the driverquery command it showed the sameinformation as previously, even when I rebooted the system and ran it againafter the reboot, but I believe unchecking the entry in autorunswill stop it from loading into memory when the system boots. The entry wasstill unchecked in autoruns after I rebooted the system.

And by using the freeInstalledDriversList utility from Nir Sofer atNirSoft, I was able to verify thedriver is now disabled. The InstalledDriversList program showed a yellow icon to the left of Trufos, which indicates the driver is not running on the Widows kernel and the 'Startup Type' was shown as disabled.

I had installed BitDefender Antivirus Free Edition along with many otherantimalware products while trying to rid the system of malware that the user'sreal-time antivirus software was unable to detect and eradicate. I had removedsome of the antivirus/antispyware programs after I was eventually able toeliminate the problem. I didn't remove BitDefender Antivirus Free Edition dueto being unhappy with the capabilities of the software; I've often used the BitDefender Rescue CD to assist in eradicatingproblems that haven't been eliminated by the antivirus software runningunder the Windows operating system on systems. I suspect that the uninstallroutine didn't remove all elements of the BitDefender Antivirus Free Edtionleaving trufos.sys behind to be still loaded into memory whenthe system boots, but the user should no longer see the error related toBitDefender Threat Scaner now.
