Avast Pro not detecting Win.Trojan.PCRat-1

system · 2015-07-27T14:26:46.000Z

As the subject header says Win.Trojan.PCRat-1 just sailed past my avast pro this morning, I knew something was up when my pc suddenly developed hiccups and started to slow down, I had already done a virus check and nothing was reported.

I have used ClamWin free via a usb stick and the following has been reported by ClamWim
Win.Trojan.PCRat-1
Win.Worm.Vasor-9

so why am I paying for a virus checker and the above just bypassed Avast Pro and a free virus checker finds it straight away

I am not a happy bunny atm
