Thanks for all the replys, regarding all-in-one, I mean't that I didn't want to have 2 different programs both for different things which both take up resources, and think that if I only have one program it's easier to manage and update etc.
I can't remember the last time I had a virus, so maybe using two isn't really the most efficient for my needs (only go on for general browsing and games mostly). I think I'll go with MSE, it's by Microsoft so will --hopefully-- not have any comparability issues or bugs in the near future.
Again, thanks for all the replies,
Oliver
