This error is a sign of the system malfunction. I bet you’ll find on the web info saying that it is all related to IE8, but in fact, this error might have many different real causes with almost the same error message:
“Windows cannot find ‘null’. Make sure that you typed the name correctly, and then try again”
It just means that there is absent or erroneous information in data files necessary for the accurate working of some application or the system programs and the malfunction is due to the file corruptions or corrupted program settings in registry or the malware activity. The error might be caused by unfinished or incomplete install and uninstall processes, deletion of software and device files without proper resets in the system registry, causing unresolved conflicts in the system memory. It might be caused even by a simple improper system shut down. The problem usually has just the same effect on the system even if it comes after contamination of PC with viruses or spyware attack. Though, there might be a malware that produces this error box just to make you click the button. It is also possible that the error message comes after your antivirus deleted infected null.exe file.
The simple steps that you can take to fix the problem
Don’t panic if you get windows cannot find null error and remember that sometimes a simple restart might solve the problem.

The next thing you can do without going too far in technical stuff is a simple restore to some saved system restore point made before the date when the error first had occurred. For this you need:

Note: The instructions for Windows XP are slightly different on names in menus but it is fairly easy way to find ones you need. On the other hand, there is a bit less chance to fix the error by the System Restore in Windows prior to Vista because the system restore mechanics is a bit different as compared to some less potent system restore technology used in Windows XP and previous versions.
Possible hardware problems and conflicts
The windows cannot find null error might be caused as well by the problems with your hardware and the malfunctions that come from its failures or improper use. There might be overheating related issues or too small amount of available disk space. There might also data corruptions caused by bad hardware or improper install/uninstall processes. Try to take these steps to check for this kind of issues:
- Make sure your computer vital components aren’t overheated. Excessive heat might cause problems in processor and some devices such as memory cards or the hard drive controllers.
- If you have a hard drive disk 2GB or smaller, be sure to have at least 200MB of free space on the hard disk. With bigger sizes you will need about 500MB free. This is necessary for a swap file and temporary files needed for system. The best way is never have it less than 15% of the volume.
- Run Scandisk or an equivalent program to check the hard disk for possible damages. These programs might restore some corrupted files from failed sectors. Check on disc fragmentation and run Defrag if necessary to bring files in order and reduce the amount of too small clusters for the free space.
- Try to remove or disable the programs that start automatically after the system boots.
- Look at the Device Manager for possible conflicts and try to resolve them.
