Could I get some infomation on these two please. I just installed AVG after deleting Norton Internet Security 2005 off this computer. The HP one Norton does not say anything about that one and it is located in the HP folder file for my printer, but the other i just seeing today. The HPWuSchd2.exe is located according to AVG at C:\Program Files\HP\HP Software Update\HPWuSchd2.exe...It is labelled as Trojan Horse Downloader.Generic4.CFV what I am wondering is why Norton says its fine and AVG picks it up as a baddy. The Wuauclt.exe C:\Windows\wuauclt.exe This is all on the main computer at work.
