Ok hi everyone,I'm new here,anyway,i need help. recently i downloaded avast! home edition and installed it. it screwed up my computer,maybe my computer's has the wrong requirement or something,my computer froze after every restart since it was installed. so i had to restart my computer then,shut down avast from the task manager then system restore then delete all the avast files because when i tried to uninstall it,the computer freezes. NOW HERE'S A SECONDARY PROBLEM,since i system restored then deleted all the avast! files(a improper way to uninstall a program). something tells me some files are leaved behind that are not in the program file folder or something. everytime i start command.com or cmd this message appears :
"C:\WINDOWS\system32\command.com
C:\P0program Files]Alwil software\Avast4\aswMonVd.dll. An installable virtual Device Driver Failed Dll initialization. Choose 'close' to terminate the application."
and i have no idea how to fix this,i searched a lot of websites for solution but i can't find any ways to fix this online. so does anyone know how to fix this and tell me please,thanks
