Lexmark printer driver. Look in same folder (eg Windows\System32) for related "Lex" files. If not longer needed use Lexunst1.exe to remove all the files. Does NOT show on installed program list under Lexmark or MarkVision. Also look for "extras" components such as c:\LXKZ32\ folder, also not shown on installed program list.

It strangely appeared a few days ago. I had a Lexmark Printer a long time ago but uninstalled all the software when I got a new printer. The person who created the virus must have named the virus after required system files. If you have a Lexmark keep it otherwise delete it or disable it in msconfig

The file Lexpps.exe is used for peer-to-peer networking support for our inkjet products. If you do not want peer-to-peer support, you can simply delete lexpps.exe and lexp2p32.dll. To remove these files: 1. Search for the files LEXPPS and LEXP2P32. 2. Delete all copies that are retrieved. 3. Once the files have been removed, you will need to restart the PC before the peer-to-peer service can be disabled. You might still receive some warnings from the BCE server. 4. To prevent this, you can use a system driver that does not install the BCE server; this driver is available for Win

Causes ten year old Windows 98SE computer to randonly lockup. I dumped my Lexmark printer for a duplex Cannon inkjet. I started getting random lockups and eventually had to reboot system. Until I realised, I had to frequently save files I was editing. By trial and error I found it was the Lexpps file causing the problem. I simply use Cntl/Alt/Delete command to show open programs and end Lexpps.

LexPPS.exe: I've worked on many computers and noticed that this program sometimes interferes. It comes with some printers and probably has to do with networking (and accessing the Internet) only. I've heard that this program is sometimes hijacked. I tend to always delete from the registry (RegEdit) and remove this file and any references. I never see any negative effects (sometimes positive), but I've yet to know someone networking these printers (possible adverse effect if deleted). If you're not sharing this on a network, at least block it from the Internet (FUTURE: "The GRID").

Best practices for resolving lexpps issues

A clean and tidy computer is the key requirement for avoiding problems with lexpps. 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 doing a repair of your installation, or in the case of Windows 8, 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 lexpps.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. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
