hi i have windows 7 and recently i scanned my computer for virus' using avast. a few files were found and I tried repairing and deleting and none of the options worked. The next time i turned on my computer none of my programs are able to start including internet explorer,itunes, avast and every other program. I have to use IE 64 bit to be able to go online. Im pretty sure its the virus or something that is causing this, any help is appreciated.
