I think then, that i'll start afresh with a new drive.
If i do this do you think there is any risk of contamination once the current one becomes a slave?
I intend first to save current settings, put in new drive as master, set old hdd to slave, install new windows, then wipe old windows.
Can i assume that wiping old windows will kill any nasties that i have in there?
Lastly if you don't mind, is my current security system adequate, as I don't understand where this threat came from?
I use Avast free, Zone Alarm free both always on. Advanced System Care Pro always on, and occasional scans with SAS free and MBAM free
Thanks
