I have a 7-in-1 card reader and it's been on my PC for a long time. I would think it is legitimate. (have HP/WinXP comp)
for hp multimedia card reader
if you don't let it run the card reader won't work
I have this card reader built into my notebook PC and the shwicon2k crashes often
It's used for the Alcor UB-6000 7-in-1 card reader and is the driver for Win98 and Win2k OS's. Alcor have not updated these drivers for WinXP and, as far as I can see, have now removed all support from their web site for this reader.

This is the driver used for the UB-6000 7-in-1 card reader that I have. It's not great with WinXP but there has been no upgrade on the Alcor site for anything other than Win98 and Win2k

This file showed up after I installed a driver for 7-in-1 card reader to download digital photos from a flash card
Just started showing up non functioning when I start my computer. Do not know where it came from and I dont know how to find out if I have a jultimedia card reader.
Bought a flash card reader off of Newegg and it came with this on a CD. Perfectly safe. All it does is change the icons for the drives in My Computer.

Part of multicard reader
that is card reader software for show in my computer icon about SD,MS,CF, smartdisk
it made my computer crash very often, don't use it.
this shwicon2k.exe screen started showing up when I got a Mobile Broadband Card. When I put the card in the PCI slot sometimes it doesn't recognize it. I'm suspecting Card reader.... there must be something wrong but what. I used Security Task Manager to track down that it's from SunKis......and it's not active on my computer......don't know why yet........
appeared after installing 19-1 card reader (LG)
It's part of HP so if you have a computer that is HP, you should have it on right now.r
Driver for 7 in1 card reader

Definately OEM Software for mobile laptop cardreader those getting crashes on this file your file is corrupt, startup service can be disabled, or can be uninstalled if card reader is not used. most do not use so disable will make your system run a little faster if you dont use card reader

Best practices for resolving shwicon2k issues

A clean and tidy computer is the key requirement for avoiding problems with shwicon2k. 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 shwicon2k.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.
