I used this site maybe 8 months or so ago and it worked just fine. A few minutes ago (April 19 2018) I went there to convert a new youtube video. The conversion happened like normal. Then I started the download. MacAfee then came up to warn the site was untrustworthy. I then closed the window. Later this evening I came back to the site and again converted the video I was interested in. This time no MacAfee warning at the point of downloading. Unfortunately then a bunch of pop ups began to appear wanting me to download an app. I declined but the pop up kept appearing with further prompts such as "are you sure you want to decline". I couldn't get rid of the prompt even though I declined the app several times and tried x ing out the prompt to close it. Since I refuse to download something strange into my computer the only way I was able to proceed was to turn off my computer and reboot. No idea what's going on or if the site was trying to put malware into my computer but I have no interest in finding out. I won't try to use OnlineVideoConverter ever again.
