You could do all your web surfing withing a virtual machine.
The virtual machine can be configured as a bastion host.
After 3-4 months of surfing, delete the VM. Clone a template. Keep on riding.
You will want to save links, profiles, and other permanents to a shared drive.
I recommend Oracle VirtualBox for desktop virtualization.
For hypervised virtualization, I'm partial to either XenServer, VMware, Xen, or Hyper-V ... in that order.
