Looks like our home PC has picked up a trojan virus, Kapersky has found this,

trojan-psw.win32.mifeng.fj

Any advice on how to get rid of it?

I've been running mcafee with the windows firewall. Ran spybot and malaware and neither found anything. I ran the online kapersky and it found the virus.
Done a google and I can find lots of tools to remove - at a cost..

Surely there's a cheaper way, given I'm supposedly protected.

 

I would try AVG... Win32 is Internet related. there is one going around at the moment that hacks your isp and blocks you from Internet access. i would try to delete this before it gets to that stage.

Try AVG... also try Malware bytes *spelling*

other then that just keep googling. Yahoo usually has some helpful forum advice to virus detection

 

Download Malwarebytes here is link http://www.malwarebytes.org/

 

If kaspersky found it why not use that to remove it??

 

 

The virus creates this registry entry :

Locate it & zap it to prevent the virus starting on boot.
It drops this file :

Again, locate it & kill it.
