Okay, so I did a full hdd format using killdisc and a clean install of windows 7 64bit.. again!
The first thing I do is try and install Norton internet security 2012 and It won't let me install saying 'install file cannot be properly validated'.
I have done a quick scan with combo fix and it came up with this log file would someone mind having a look please.
Do I have a memory virus/malware?
Thanks very much for your time.
