Program Managed to install malware outside of Sandboxie while running in it! Full of Malware that messes with your browsers, and installs without your permission! Has two screens that you can op out on, but still installs malware, redirects you to sites that display screens saying your infected with malware, buy this to remove, or a fake Microsoft site that tells you to buy another program. On one site there even an ad at the bottom saying ads by YTD! Program managed to install malware in Chromodo browser even though I ran it in a sandbox program Sandboxie, for some reason it didn't manage to install malware on Chrome probably because I was running that sandboxed and using it to download the file off download.com, it also reset windows to hide hidden files and folders. This programs installer will install malware on your computer even if you run it in a sandbox. Also it is undetectable by 100 antivirus engines. You will spend hours trying to find the infection and fail, and will have to remove your browser program and manually delete any left over files, and run registry optimizer and then re-install the previously infect browsers, and who knows maybe they will get reinfected? Believe all the reviews that tell you this software infects you computer, and don't be leave the reviews that say it's the people installing it not opting out those are just planted reviews!

Converter itself is very safe, no problems with that Its just that when you are installing it, it gives you an option wether you want to install the Spigot Toolbar or not, even if you untick it (chose not to download) it downloads by force its been causing serious issues on my laptop and im thinking of wiping it clean soon. Ive used many malicious scanners and have a anti virus

Used to have been one of the greatest software to download from Youtube. But now it's one of the worst. After installing it, I got a pop up saying a program was changing my default search options. I felt unsure so I ran a quick scan on Malwarebytes and it found the problem. It found 8 unwanted software coming from a Youtube Downloader Toolbar from Dealio. Never will I use this program again. Plus, Freemake Video Downloader is way better and comes with no spyware or adware.
