Based on internet searches it forms some part of Windows security checking. I get sporadic requests to debug it. In addition it does not appear in add / remove as suggested!

It also appeared after installing IE8 along with 45D.exe and randomly starting up MSN when I'm playing games. Advise: Disable because it isn't essential. DON'T get IE8. Keep to 7, Firefox, Safari or whatever. I would classify it as Malware because it simply isn't needed. Technically, there's nothing wrong with it.

When my cpu is 100% and wont clear, I stop the infocard.exe process. The cpu then clears itself and allows other programs to run. I think it is hiding malware.
Got a message in Windows Live Messenger from my daugther today, which she did not send me. It was an automatic message with some Hahaha (something like that) containing a link. Sho got the same message from others and opened the link. After that a file called infocard.exe has been downloaded into C:\Windows. It was between 80 and 90 kb, it was flagged hidden and system file (meaning you can't see it unless you are choosing to not hide system files). And it was in the registry HKLM\Software\Microsoft\Windows\CurrentVersion\Run (meaning it starts every time someone log in to the computer).
It can be viral and cause problems with MSN allowing spyware in
I recieved an alert of WORM/ifnocard.exe in my Antivirus,and I had Malware/Spyware on my computer,so I am guessing this was the problem.
infocard.exe may be the cause of the so-called "PHOTO" virus. It sends messeges to all your friends in Instant Messaging applications with some link.
This just suddenly appeared. Even if it is "harmless" it is harmful because I never did anything to install it. I like to keep my system clean and I only want what I install and use to be installed. Thanks Microsoft for "giving"me this "feature" I never wanted.

Best practices for resolving infocard issues

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