Apparently when you order a laptop or computer and have it shipped to you, there may be a very high chance that it has been intercepted by NSA and a group that is known as the TAO or ANT program that secretly unpackages the electronics and installs spyware or malware on the machines, then repackages them like new and sends them to the customer.
Gee thanks NSA for slowing my machine down, fuckers.
