Hiyya Noel since I posted that I have been able to get onto the net and download CC and MBAM. I actually had to run the CC in safe mode in the first instance and the first MBAM scan which I did not include the file system to be a little quicker.
Now I have deleted a lot of very suspect apps ( a lot of P2P ones) but the boot still takes 8-10mins and clicking on an app takes at least 4 mins to open it.
I have found 33 trojans with MBAM and removed 34GB of rubbish with CC done a thorough defrag, SFC /scannow, chkdsk, and run the Kaspersky TDSS Killer in case it has a rootkit lurking. The SFC did say there was some corrupt files that could not be fixed but I have plodded on.
No rootkits and the last full scan with MBAM turned up the last two trojans.
What I don't get is that the HDD runs real fast in safe mode but in a normal boot just ticks away almost like a clock - real regular and not the frenetic clicking one usually hears.
I am going to run a Seatools check later tonight to see what the HDD is like as perhaps it might be going south.
There are two other problems one is the usual no disk - rescue or installation and the cover for the HDD has one of the screws cross threaded in and th head stripped out so replacing it is going to be hard.
I have told the friend that to fix this one will take a new HDD and maybe a 7 OS and given the battery is cactus the repair bits as I can only get them retail are worth more than the fixed machine would be.
It is a shame really as it has been looked after on the outside the inside however wrecked with P2P and Apple apps and I also found that Registry Mechanic app in there too so who would know what the dickens is wrong with it. Clearly the security (Norton) has not been very effective IMHO and it seems that just when I have got on top of things it slows up again.
