What are the Common Errors Caused by Csrss.exe Virus?

Firstly, please note that the csrss.exe file is a legit and crucial Windows system process. For this exact reason, hackers and malware creators have decided to use this process name to pretend that it’s part of your system.

As a virus, the csrss.exe file can wreak untold damage on your PC; as a Trojan, it can sneak into your PC and retrieve all your private and important financial information.

Here are two basic facts you need to know.

Fact 1: The csrss.exe file resides in your C:\Windows\System32 directory.

Fact 2: The csrss.exe file is NOT a very big file and utilizes minimal CPU memory.

If you see this system process as not meeting the above two criterion, it’s mostly likely a worm, virus or Trojan and removing csrss.exe should be your first course of action.

Csrss.Exe Common Problems

The following are some of the usual errors caused by this malware.

STOP 0xC000021A error.

This error is generated when Windows detects that the (real) csrss.exe file has stopped. One of the reasons this may have occurred is when the file has been corrupted by the ‘fake’ csrss.exe.

High CPU Usage.

When you PC slows down all of a sudden, open Windows Task Manager and go to the Processes tab. Check that the csrss application is not hogging your system’s resources. (Usually this will show that it’s using 90% to 100% of your CPU).

Browser pop-ups and/or redirections.

As a Trojan, csrss can redirect your online efforts by offering pop-ups that have absolutely nothing to do with what you are viewing or sending you to lottery, casino or even adult-related sites.

Computer freezes and crashes.

As a virus, csrss can cause your system to crash completely, causing you to lose valuable files and documents.

How to Get Rid of Csrss.exe Errors

If you think your PC has been invaded by this virus or Trojan, it is of course in your best interest to apply the following csrss.exe removal instructions right away.

• Run anti-spyware and anti-virus software to seek out the fake system application and remove it.

• Run a registry cleaner to remove any remnants of the deleted virus or Trojan from your Windows registry.

• You can edit your corrupted user profile to remove csrss.exe errors. Why this solution? Worms, viruses and Trojans come from somewhere. Try as you might to avoid ‘dubious’ sites and no matter how careful you are in downloading stuff from the internet, some of these resources may have been to source of the problem and it came through your user profile on your system.

To get rid of the virus or Trojan, you need to address the corrupted profile first because each time you enter your Windows system using this profile, the fake csrss.exe file is activated.

• And the most painful solution… back up your important files and documents and reformat your hard disk before installing Windows again. (Note: this mostly works only if you do a FULL reformatting and not just apply the Quick reformatting option. Sorry…)
