The CSRSS.exe file

Many times, when you are running a virus checker on a windows machine, a file called csrss.exe will pop up and the end prompt and show that it is infected. You don’t really know what this file does, or if you need it.
It looks like a Trojan or a virus. You say to yourself “I don’t need this file. All it does is cause problems. I am going to delete it!” STOP!

The csrss.exe file is stored in the c:\windows\system32 folder. It is a critical system process that will cause very big problems if removed. Don’t even try removing it from the task manger. It will still cause operational problems in your operating system. Don’t touch it.

Now, this is a critical system file, but it is easily infected by spy ware and trojans. That’s why it is always showing up in your virus checker. It is best to let your antivirus program deal with this and not worry about it.
There are rare cases when this file will become corrupted. One of the ways you can find out if this file is corrupted is by simply opening your task manager. If it is using over 95% of your CPU or another abnormally high amount, there is a good chance this is the problem.

Don’t worry, though, this problem is easily fixed. This problem is related to a corrupt windows profile. Here is an easy way to remedy this problem.

1. Backup all necessary files in the profiles “My Documents” folder.
