Hi, Having followed your given instructions for removal of anything malicious from my computer I think i've managed to rid my laptop of a few trojan horses and various other tracking cookies etc... However, the underlying problem I was having with the machine is still there: it's incredibly noisy - especially when I open up programs like Messenger or iTunes and then will peak before switching itself off lasting anywhere between 40 minutes to 2 hours. When I try to switch it back on again, it might take 3 or 4 times before I can get as far as the Windows symbol. Then it takes forever (15mins+) at startup if it does load. So i'm wondering whether something more vicious has now been unleashed, or if the problem is the fan or a combination of the two...! Please find attached my HJT log. Any advice would be gratefully received! Best wishes.
