Hi, I have been using YTD Downloader for a few years and I have had no known problems, until the last software update. Directly after updating the software a program called Winzip Registry Optimizer started to run, and supposedly scan my registry. I was suspicious, so I googled it and apparently it is malware and very difficult to remove. I also googled YTD downloader and it seems that it is bundled with malware and also very difficult to uninstall. I was using Bitdefender up until a few days ago and am now using Microsoft security essentials, and neither program reported a problem.
I'd appreciate it greatly if you could advise me on a course of action.
