Hi I have removed winstall.exe by deleting the winstall.exe in C:\. However now my laptop is having other problems. One of them is that when I run registry mechanic, it'll start another program which installs a program that I have removed from my laptop. Next whenever I switch on the wireless switch, a warning message appear saying that the computer will shut down in 1 minute. I have no idea how to fix these problems. I've tried using registry mechanic and spyware doctor but the problems still exist. Please help. I'll attach my hijackthis log.
