It is only a problem on this PC in the house.
Despite an ethernet connection, some websites do not load (like Yahoo) and other websites do load, but slowly. The Youtube website loads completely, but videos load slowly. Trying to reach a new version of flash will not load. (White screen and loading symbol in the tab.)
I had this problem before, but I did a factory reset which seemed to fix it. But it appears it hs happened again. The computer was running fine for almost a year before I had to to the factory reset.
Any idea what the problem could be? In the meantime I am going to do a Malwarebytes scan from my phone onto the computer.
