Nope, it is not my PC, I am extremely careful with every single thing that I do with it.
I have no P2P software, I have my security and privacy settings on high and medium high. I have ad-aware, spybot, norton internet security, and check for updated virus definitions twice a day (just in case). Nothing gets installed in my computer or changed in my registry without my knowledge.
It may sound like an exaggeration but I sleep well at night
Anyway, none of this has changed and then, overnight, the difference in my adsl connection was noticeable from 31 July to 1 August.
