I just downloaded and scanned with AVG 2012 Free Edition. Various virus lines showed up which I deleted successfully....however I got 9 that stated Win32/Patched.HU "object is white listed(critical/system file that should not be removed)" I am a senior who is new to computers...this sounds serious...what should I do? The file states C:\Windows\SysWOW64\user32.dll Your patience and help is really appreciated...in advance.
