it showed up after the PC restarted on its own
its marked in running processes from Microsoft Antispyware Beta 1
It comes with a prefetch" KNLWRAP.EXE-090F9024" and turns legitamate programs into key-loggers. Also check to see if you have "KILL.INI" and "KILLAPPS.EXE" on your system. Until I isolated these in a file it even caused my d-link 604 to reset itself. ZA Pro stopped it all but could not identify it as spyware, nor could Spybot 1.4 beta or ewido. It's been a long 10 days trying to isolate the problem.
after downloading a keygen popped up in the C drive (along with a few other files set to hidden that i'd never seen before) i us the python scripting program (Python 23) and after i got a aton of other viruses knlwrap popped up in a suspicously placed (python 22)

Zone Alarm says it Monitors Keyboard and mouse movements

I had Webtrends installed on my computer, I uninstalled it and that process went off my list
installed in InstallShieldEngine folder
A prefetch module in Windows XP; may be part of install shield. It monitors your keyboard and mouse movements and tries to access the internet during uninstall of Roxio Easy CD Creator 5 Basic.
it has something to do with installing diskeeper
This gets installed with ABBYY FineReader 5.0 Sprint that comes with the Microtek ScanMaker i320 scanner

Is a program that removed symantec and prevented any virus or trojan detect software to be loaded onto the workstation, its only after I canceld knlwrap and Ikernel using the task manger that I was able to delete the folder. Once the folder was deleted, I had to do a registry hack and remove all signs of symantec to reinstall the client.
I noticed first noticed this file when I was installing the Plus! pack for Windows XP. It also was in evidence again when I ran the Plus! service pack. Zone Alarm Pro (current), and Symantec Antivirus Corporate (current) didn't pay it any mind, other than the Zone Alarm suspicious warning.
ZA issued warnings about knlwrap.exe and I isolated knlwrap.exe to a separate folder - ZA no longer issues warnings and I have not had any problems with installed programs. It does not appear to be essential to any program or process.
It showed up when installing Microsoft Plus! SuperPack for WinXP. Zone Alarm says it is a keylogger.
Part of the InstallShield set - fires up every time an Install Shield runs
Installed Microsoft Comfort Curve Keyboard 2000 and then found Knlwrap.exe.
I think it's key logger, but I'm not sure, I'm still investigating
It's a keylogger
It tried to install itself when I was installing the drivers for a Canon Pixma MP 130, apparently it came "in" the installation software. My ZoneLabs software caught it and reported as suspicious.
Another MS vulnerability. If not required for you specifically remove it.

it is not needed do not install it if asked to buy your security warez, just deny and move on if it is legit this will not impact your current install of whatever.

As I installed Roxio Easy CD Creator 5, Zone Alarm detected knlwrap.exe in the C:\Program Files\Common Files\InstallShield\engine\6\Intel 32 folder.
since this file appeared in a warning in ZA that my pc restarts on its own and my anti-virus was disabled
Someone mentioned EZ CD Creator and I recently uninstalled a part of that (v6.x) in order to install a nero equivalent. Since then every time I paste a short cut I get an install dialog that says something about EZ CD Creator...TWICE. Maybe this is the source of it.
This file seems to be a spammer application! I installed McAfee A/V and found that my system is sending junk mails!!! Then while debugging found that knlwrap.exe is the cause!! I removed (moved) this file from "C:\Program Files\Common Files\InstallShield\engine\6\Intel 32" my system stopped spamming! I guess the file "scpthdlr.dll" accompanys this knlwrap.exe...
Kept trying to access the internet.. Looked a bit shady, and following reading the entries in here (thanks Spad) I decided to obliterate it! deleted all references to it off the hardrive and used regedit to remove from registry also... now.. i'm not sure if this is a coincidence but my internet access speed has gone up from around 700kbps to about 3500kbps..
It comes with McAfee Quickclean

unpacked in C:\Program\Delade filer\InstallShield\engine\6\Intel 32 when i ran easy cd creator 6 install
popped up out of nowhere and is using a fair amount of processing power. i've just been a victim of internet fraud - i think this is a keylogger and would recommend you remove it.
Activated when an unistall was undertaken - probably agreed with the fact it's an InstallShieldEngine issue.

When I install Canon PIXMA MP 150 Printer Scanner, Symantec EndPoint Caught it up as Bloodhound.SONAR. 2. I put this in Quarantine
installed when installing trusted Pfaff sewing machine software

Best practices for resolving knlwrap issues

A clean and tidy computer is the key requirement for avoiding problems with knlwrap. 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 knlwrap.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.
