It is a service used by Windows to allow execution of VBScript. It is not necessarily dangerous, but if a dangerous script is downloaded it will appear as if wscript.exe is the culprit, when it is really a seperate script file (usually .vbs). You should not delete wscript.exe, many Windows services require it and our computer may not function properly if it cannot be found.
want to change file type associations. .scr - .vbs - .vbe - .wfs all to use note pad
whenever we start the m/c and boot after booting then wscript .exe error is coming and when we disconnected the floppy drive the error is not coming

Nasty script vbs file that is virtually undetectable, shuts down your registry access and even after setting it right locks down the registry again. Smart PC usage can prevent further attacks
Every time I eject a CD/DVD it pops up an annoying error.
It is used to allow more scripting features - this in itself is not dangerous in any way, but it is sometimes used by virus'. You won't be able to remove it as it is a windows system file.
It seems that it is disguised as a proper windows scripting host, however, looking at the code embedded in the file placed in my flash drive by the virus points toward wscript.exe in the system32 folder
seems to be a virus 4,300 +/- bytes C: & C/Windows

I want to know the functionality of wscript.exe. What it does and how it works?
wscript.exe eats up over 50% of the CPU, can't be stopped, and disappears and reappears in the task manager every few seconds. Virus masquerading as the program.
This was shooting up my CPU's resources higher than anything on the list, I run an unlocked overclocked processor and to see this taking up 50% or more was bizarre, so I removed it. Seeing as this can be a horrible back-door vulnerability issue I see no need to keep it. Visual Basic is seldomly used in any everyday application even for casual users or heavy gamers such as myself, delete it just to be safe.

If you have any problem with wscript.exe dont be panic if it flash on your screen while you start your computer. One simple thing to do is just go control panel system and security restore file from backup recover system settings or your computer open system restore next finish wait till it restart the system. Note: it wouldnt delete your document or install software but bring to default settings. Reccomended for win7 only. Hope it work because i have try it.
wscript running make autorun.inf and a virus file in my pendrive, even if after formatting the autorun file and suspisious file appears. This phenomina was ended only after i manually ended wscript process from taskmanager manually. now my first process is to end wscript process from my taskmanager manually.
Made my computing experience a ni8mare by replicating a virus file and displaying system errors
It is a virus
If there is a virus download procexp.exe from sysinternals and kill wscript.exe

i would not recommend removing it from your computer it is required for many windows functions. however, it is also a portal for many "viruses" to enter your computer. if you see it running on your computer and odd things are happening such as high cpu then sweep your computer for malware/worms/trojans
Don't delete, idiots. It's part of windows script language and needed by the system. It's NO virus
It wasn't in my laptop I checked multiple times until I downloaded something
Randomly would get a pop-up saying that my MS Office needs to be repaired and then after a few minutes I would be prompted to restart. Upon doing this daily I have come to find it is coming from this .exe file. If I force close this repair pop-up it would close all my MS opened applications causing me to lose unsaved work. Deleted it to prevent future loss of work. I needed to mess with the permissions of this file as the owner was "TrustedInstaller" and as the system admin that was not enough. You need to switch the owner to yourself, delete the TrustedInstaller permissions, and then give yourself full control of this file before being able to finally delete this stinker!
It is not a virus, it is a part of computer os. BUT some virus can modify wscript.exe THEN ONLY it damages your computer.

Best practices for resolving wscript issues

A clean and tidy computer is the key requirement for avoiding problems with wscript. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the wscript.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
