full-scan (208,000 files) only 7-10 mins??

My dads laptop has been hit with the fraug toolkit as has his PC on the gumtree website - he has done a ful scan which was clean BUT the scan only took 10 minutes and he says 5-7 minutes last night...

 

how can this be? - on his PC and my laptop its much slower but the right amount of time for full scan?

 

he doesnt have an SSD drive installed - just a reg laptop for £369 Toshiba Satellite Pro 

 

thanks
