Autorun needed by Lexar USB keys

Lexar makes sense...I just got a Lexar SecureII USB drive. What is surprising is that the only time I saw it was after just installing a MS update. It is now leaving a window up with Exit as the only option. I had the drive for about a month before this happened.

Lexar USB connected storage files
flash dirves won't run when it is running
Part of Lexar jump drive security. Just unclick the box at "enable quick start on this computer" on the settings area of the jump drive

Installed WITHOUT ANY PERMISSION from the user by Lexar USB drive which makes it at least VERY SUSPICIOUS. I will remove it from my system for that reason. If The lexar drive asked anything BEFORE installing this on my system it would be ok but this kind of install is unacceptable. There is no mention of this in the documentation wihich makes it even more suspicious. My advice it to KILL the process LxrAutorun.exe and REMOVE the complete folder C:\Documents and Settings\Ā«usernameĀ»\Local Settings\Application Data\Lexar Media
Useless and preseumptuous. installed without permission. dangerous because it uses resources and changes behavior without permission
after using a usb the first time it was on the compuer. numerous actions have started that are not helpful

Best practices for resolving LxrAutorun issues

A clean and tidy computer is the key requirement for avoiding problems with LxrAutorun. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the LxrAutorun.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
