What is “csrss.exe”?

Csrss.exe is an integral part of all Windows operating systems: without it, Windows will cease to function. Csrss.exe is a computer utility that stands for Client/Server Runtime Subsystem and it is basically a directory of files that manage Windows. It is always in the “c:\windows\system32” folder, but should you find it anywhere else—you most likely have a virus or Trojan (which are for all intents and purposes of this piece, basically the same thing).

Csrss is commonly used to infect computers

Evil people who create viruses love to nickname their viruses with either cute little names like “Zlob” or serious names like Csrss.exe. The latter file types are used with viruses primarily because they help to disguise the virus that’s in your file system as just another registry entry. The benefit of doing this is confusing unscrupulous users into downloading a seemingly helpful file. It has been advertised as a virus removal/virus protection program and also as programs like “Employee Watcher”, Buchon, Meheerwar, IETray, Findwhatever and so forth.

Determine if you have a corrupted or infected Csrss.exe folder

One effective way to discover if you have inadvertently downloaded one of these Csrss.exe imposters is to check the Windows task manager (alt + control + delete). Under “processes”, make sure there is not more than one Csrss.exe program running—which should be the legitimate one. If you are unsure, refer back to the Windows32 rule: it will be operating in under c:\windows\system32.

Furthermore, look inside your system startup folder; if you find crcss.exe in it, it almost certainly a virus, Trojan or worm. If this is the case, immediately acquire a trusted virus removal software program (McAfee, AVG, Norton, Avast, etc). If you still have web access, then search for “Csrss.exe removal tool” and ONLY download it from a website that you trust 100%.
