For years I've cleared the drive (DBAN will do) then used the restore media.
Why would I pay for this?
As to your question, depends on the pro. Some are good, some wear the badge.
I am thinking of selling my laptop. I will take it to a professional who will clear everything. If there was some kind of keylogging virus or keylogging software that had been put on it, will this professional clearing get rid of that as well?
That's the reason I am selling it.
Thanks for your help.
