The fact that your system has been infected on multiple occasions is worrisome. Even though you use MSE, there are any number of other measures you need to take to avoid malware (most come under the heading of "best practices" if you will). You say some things don't run properly and you want to know how to "clean up" your system. Exactly what is it you want to clean up?
Thanks for your reply.
To the best of my memory:
The first infection - I was using AVG, tech at computer shop fixed and changed to MS security Essentials.
Second infection - was cleaned up. Although I do have a niggling doubt that MSE upgrade might have been after the second infection - that would make more sense.
Third visit to store (definitely with MSE) wasn't actually a virus (so it's possible I haven't been infected since the change to MSE), I was told there were too many programmes running in the background and they were cleaned up (a bit vague to me!).
So, I'm usually connected by Ubuntu unless I really need to use Windows.
If I do use Windows, I update and run MSE whenever I connect.
I use Firefox instead of I.E.
I also run Malawarebytes - no threats/items were found in todays's scan. I also do a disc cleanup/defrag
I want to clean up whatever it is that runs in the background that shouldn't, even though I don't know what it is (if that makes sense). What was the computer tech refering to when he said there were too many programmes running in the background (I did ask, but this is how he makes his living after all so wasn't too forthcoming).
