Application cannot be executed. The file --- is infected

[razr.nps]

Hi,

I am working from home. Unfortunately, my office laptop got infected with virus. I get the message "Application cannot be executed. The file *.* is infected' whenever I try to open any application. I dont have admin rights on this laptop.

I booted in SAFE MODE and -
I downloaded "Super AntiSpyware" and deleted all the Trojans that it detected.
I am not able to install "Malwarebytes' Anti-Malware (MBAM)" as I dont have admin rights.
I also installed Hijack This.

"Super AntiSpyware" didnt remove the virus.
I had the same problem earlier. I read a post where they asked me to delete some specific REGISTRY KEYS. And it worked. But I am not able to find that post now.

If I call my office support, they can grant me admin rights only if I am connected to my office network. But I am not able to connect to office network in SAFE MODE.

Someone please help me!!

You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.
