DO NOT BUY THIS. Your digital security will be permanently compromised. In the first few weeks, I didn't notice any particular issue except that the computer was a bit slower for the year/specifications. But it worked okay, except being constantly slow. I thought it was just a performance issue. Beginning around week 8, when the Amazon return window closed, Safari started changing the default engine by itself and installing malicious extensions and background daemons. The problem got worse and worse, and now the standard "settings" procedure does not fix the issue. I am sure I am being tracked.
