SetWallpaper.cmd is a virus?

[forgon]

My laptop was booting up slow so I was checking the start-up items and I saw a file called "SetWallpaper.cmd". I did a quick search on Google but there were contradicting opinions on whether this is a virüs or an OS file.

Is this file harmfull or just an OS file?

Test the file at VT: https://www.virustotal.com and post the result.

The problem is msconfig says the file is in "C:\programdata\SetWallpaper.cmd" but when I go to that path I cant see it. I also cant see it when I do a search.

Configure your OS to show system & hidden files/folders.

I already did that, programdata folder is a hidden folder.

So, can you send it now..??

Just type in C:\ProgramData in  windows explorer and hit enter and it should take you there...then you copy that file to your desktop and upload to VT and post result here

if vt finds it as malicious then open up avast UI>>maintainence>>virus chest>>click add>>select the .cmd file on desktop and click add>>and then right click on the file added in the chest and click send to virus lab>>fill in the form and select Potential Malware as the category and click send>>click OK>>Update the virus defs manually now to send the file. 

now its safe to delete the file in programdata and on desktop.

I cant see the file in that folder even when I made all files visible. But I can still see it in startup.
