I've been cleaning this log up in accordance with the tutorial file from merijn, but most of the entries keep coming back. Adaware cleaned 1157 entries off this earlier, and Spybot a further 50...

Can someone take a look and tell me what's reinstating all these problems?

ah not to worry - I had half of them disabled in msconfig, so I re-enabled and they're clean now.
