Today I faced some spyware attack on my machine and it totally controlled my machine where I can’t run any exe based program like browsers, installables, visual studio, cmd … etc
I struggled for some time and finally resolved it by doing following steps …
I tried to notice what process is running when I run any exe based program and I found it as nuk.exe. I tried to find the exe location thru process properties in task manager and then I killed all nuk.exe based processes. Later I have renamed the nuk.exe to nuk.exe.txt to stop it running on opening any exe based program. Later I deleted it.
After that I installed following spyware trail version software (Webroot SecurityAnywhere) from webroot and scanned the pc and removed threats.
After that I installed Advanced SystemCare Free software and cleaned up malware, registry, shortcuts, history and junk files.
