Hi I am just needing a bit of help on this matter. I have AVG to run my scanning but I am wanting to know if it has to scan all of my files on my pc or just the ones that are downloaded through IE and temp internet files. Does this make sense to anyone? When my pc does the scanning it takes like 3 hours to complete because I have many files on here. I'm not advanced enough in PC lingo to understand it all but I am assuming the only things that can get "infected" are either the ones downloaded or loaded on pc from another source like zip drives, etc. Any help or links to check much appreciated. Thank you.
