Having a serious problem need expert help. Okay so my printers that are installed will not show up, and when I click on add printer nothing happens. I know this sounds like a somewhat common problem. I have searched for a fix for this for several days now, nothing seems to work. as an added problem I discovered that when I am looking at my services and I click on one an error message with a yellow triangle and and ! in the middle of it pops up with no message only an ok button to click on. I think this is a result of a recent trojan I think I removed from my system. Does anyone have any ideas on how to fix this with out reformatting?
