need to understand this problem please, i was going to do a scan on my pc and there is alert message on the avast screen that says there is evidence of grime on your pc. there is a button to install grime fighter but i did not hit any buttons. i wonder how this grime fighter got planted in my pc without my permission. i did a file check in my pc and sure enough there is grime fighter in my files. i tried uninstall this grime fighter but wont go away. any one know what the heck is going on?
