Hi guys, need abit help on laptop recommendation, i am not good at reading tech news and a computer nut recently want to get a new laptop as my current wan been running 8-9yrs (vista then go to xp). Recently suddenly got scared on security wise because i only use this laptop for my personal banking stuff.

Budget : 3k (can deduct income tax)

Thank you very much
