Glad I know now! Thanks!
Since you are reading this page, you have probably heard that using a custom mouse cursor may infect your computer with malware. While there is a small danger associated with actual cursor files (discussed later), the real danger lays in malicious web sites that pretend to offer custom cursors, but their real agenda is different.
There are 3 simple rules that will protect you from malware disguised as cursors:
While following the above rules is enough to protect yourself, it never hurts to learn more details. Here they come.
First, let's look at the standard Windows cursor files. There are 2 kinds: normal cursors (with .cur extension) and animated cursors (with .ani extension).
These cursor files are data files, similarly as .png or .jpg images or e-books. Data files are usually safe - you can download and copy them around without fear. They can only be dangerous indirectly - when the application that uses the files contains an exploitable security hole. There used to be a security hole in Windows, but it has been fixed years ago. Keeping your Windows updated takes care of this problem.
Let me say a few words about anti-virus software. When the security problem with .ani files in Windows was published years ago, anti-virus manufacturers updated their products to recognize the suspicious .ani files. Some of then did a very sloppy job and valid .ani files were incorrectly flagged as viruses. If your anti-virus software warns you about an .ani file, open it in RealWorld Cursor Editor and re-save it. If the warning does not go away, contact your anti-virus provider and report this "false positive" to them.
.zip or .rar files are compressed archives containing multiple files. Before these files can be used, they must be extracted to a folder. These archives should contain .cur or .ani files and possibly some accompanying files. Focus on the .ani and .cur files, be suspicious about the other files - never run any applications that were extracted together with the cursors. Some archives may contain an .inf file that can help you install and activate the cursor files. Although the .inf file may be very handy, it can also be very dangerous. I would not recommend you to use it if it came from a untrustworthy source.
This is where the real danger lays. There are malicious web sites that pretend to offer custom mouse cursors, but instead attempt to install malware or adware on the computers of their unsuspecting visitors.
Fortunately, protecting from these kind of attacks is not hard. Use an updated web browser. Never "run" or "install" anything. Always look for .cur or .ani file (or .zip archives) and "save" them when asked (activate them via Control Panel or a specialized tool). If a web site does not offer you to download .cur or .ani files directly (or indirectly in a .zip file) and instead forces you to install something, leave as quickly as possible.
Assessing the level of trustworthiness of a web site is not trivial. Looks can be deceiving.

I'm not sure if I have malware virus or not//
Thanks a lot for a great information
is there virus in real world cursor editor please tell me truth
thanks for the info. i'm new here, and at first i wanted to turn a picture into an icon. but when i saw some cursors that include pokemon, i wanted them. once i tried to download, i saw this. i read it, and i know that i won't download from any other sites. but know im thinking... if you tell us that, then this website might be a virus holder itself!
thanks for the info. your help is appreciated
use malwarebytes' anti-malware it can detect malware and spyware
Hey this is quite helpful! My friend makes viruses but I've never seen one that is not a .exe so THIS TELLS YOU THE No.1 RULE: Only open .cur/.ani files!
