As far as I know, you wouldn't miss it until you put in a game cd. You would then realize how important it is. The copy protection program by Macrovision Safe disk. The last security update by Microsoft update took it off and now any game new or old requiring a cd in the cd rom drive will NOT RUN!!!!!!!!!!!

On Windows 7 Forums i had learned this. It is a file for authenticating games and is a known cause of Blue Screens.
The driver, secdrv.sys, is used by games which use Macrovision SafeDisc. The driver validates the authenticity of games that are protected with SafeDisc and prohibits unauthorized copies of such games to play on Windows. The secdrv.sys is included with Microsoft Windows XP, Windows Server 2003, and Windows Vista to increase compatibility of the games on Windows. Without the driver, games with SafeDisc protection would be unable to play on Windows. SafeDisc remains inactive until invoked by a game for authorization to play on Windows.

Macrovison is NOT safedisc. Guys need to get their facts straigt. Macrovision is a DRM driver that prevents playback and recording of copyrighted movies on analog video devices via computer.

It's a standard shipping component from XP onwards and it's basically a shim to make Macrovision's SafeDisc system work with these OSes. It is not unsafe, per se, a vulnerability which exploited it (and required logon access anyway) has long since been fixed and it doesn't interfere with your system beyond being part of 'protecting' certain software.
It did came as a result of game instalation and yeah it is part of the safe disk cd protection sys rated it dangerous because for some reason it doesn't alow my avast 5 to properly start (starts with all real time protection disabled)
it is added with some EA games (i found the file on the installation CD!!!)

Best practices for resolving secdrv issues

A clean and tidy computer is the key requirement for avoiding problems with secdrv. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the secdrv.sys process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
