Checking info on bad employee
So I've been put on a test at work. I am forced to share a desk with a slob, liar, and slacker. He's so far installed a bunch of programs and claimed I did it to try and get me reprimanded or fired. I need to know how I can prove who installed it, when and also after the fact that they've been uninstalled. Mind you not a wiped hard drive. The biggest problem is McAfee as it's a huge no no here to install antivirus that isn't authorized. I need to figure this out before monday.
I also need to find a way to track his internet traffic as well. He wipes his history but I recall a way to track through the registry. Any ideas?
