I'm getting some really random phases of poor performance with FS9 - I think the reason for this is that I'm at university and constantly connected to the internet, and everytime I run a spyware check there are about 20 new objects. How do I stop these coming through? Should I have Windows XP Service Pack 2? What do people do with their anti-virus software when they're playing flight simulator connected to the internet? Thanks in advance for your help.
