To buy anti virus and I suggest to use a Virtual Machine to setup a pure system.
Thanks for all the advice guys. So just to confirm, if I set up a virtual machine on a laptop/computer which I'm not sure has a virus on. If a virus is on that machine, will it spill into the virtual system and still be obtainable by hackers? Or it will be safe either way so long as I do everything specifically on the virtual machine? Can anyone confirm?? Thanks
