I have a system in my shop that will not launch any program either by clicking the icon or running a .exe through the command prompt. This is different from the .exe file association issue that often happens after a PC was infected with a virus. My customer claims that her Avast A/V found a virus and removed it and since then nothing happens when you click on an icon. I have run Kaspersky, Malwarebytes & Avast and all of them say the PC is clean of viruses. I can't run Combofix because it will not launch from the PC (I removed the hard drive and scanned it on my shop system when I used Kaspersky and Malwarebytes). I have tried a Windows repair and there isnt any restore points available before this issue happened. I did try the .exe and the .lnk fix but none of those have worked either. So I present this case to you in hopes someone has some ideas for me to try.
