I purchased a used Lenovo T430 off Craigslist. Seller said it was a fresh install, but it has always run slowly, especially when online - latency between keystrokes. Enclosed is a Roguekiller scan. According to some posts on Google, these don't appear to be malicious. Don't want to delete unnecessarily, lest Win/Office stop in 6 mos. Can someone give me advice on these and, if necessary, guide me thru an MS config and/or other diagnostics?
