    Trojan aftermath: Windows 7 Acer Aspire 5560G unable to run programs


    After running m s e it introduced a trojan to my laptop, eventually in safe mode and using a recovery disk I was able to remove it, unfortunately it's left my windows 7 home premium acer aspire 5560g laptop in a situation where it is no longer able to open and run any program , every program with an exe. file opens up a pop out screen that says do you want to open (then it names the program) and it says "save" then it does nothing, you remove the pop up screen and it just re appears, and even in safe mode even the same happens with the cmd prompt, also in f2 the bios screen it comes up with a random series of characters as a password which also was introduced through the trojan I caught, and every time you get to the password screen for the bios there is a completely different set of random characters, I eventually was able through safe mode to get to the recovery screen and run it but it makes no difference I am still unable to run any program, any suggestions please

    Did you reformat and cleaned install Windows after detecting the malware?

    In general after being infected, the only reasonable course of action is to reinstall the OS, since you don't know what exactly the malware did (and as you noted, it seems to have done quite a lot of bad stuff).

    Reformat the computer and restore from a known-safe backup.

    I have the exact same thing happening with a Bootcamp Windows 10. I got hit with Neshta, it renamed and encrypted a lot of my files, lost terabytes. After using Hitman Pro I was able to stop the very rapid progression of the encryption, but I could not start Task Manager, said it wasn't installed even though the file was where it should have been. When it asked what program I wanted to use, first I tried the command processor but that was broken too. Finally I told the prompt to open the app with the APP itself. Later, I found out I could open my apps by running them as as administrator. Of course Alejandro is correct, only real way to deal with it is wipe & reinstall. But I hope you can get any important apps running so you can save any files that need to be saved. Hitman allows you to run a 30 day trial, so it is worth installing that. Of course, I had to tell Hitman to open itself either as Admin or with it's own executable...
