The last post:
posted nearly 3 months ago (in April) said that there would be an upgrade soon to fix the problem of constant HDD activity. There has been an upgrade since (to 9.1.603.000), but I still have the HDD activity and as such still have anti-virus/Anti-spyware switched off (using Avira instead).
Has anyone else still got this problem? It's driving me nuts.
