I previously surfed the internet and went into a site that has a collection of tv series so you can watch it online, but then my mac started beeping and telling me to download mackeeper due to a virus. This happened once before, so i didn't bother downloading it again since i had it, and nothing happened after. Now my mac keeps putting pop ups that says:"Connection alert We are having troubles. Download Hotspot Shield t..." I can't get the pop up to show more. If i click the pop up, hotspot shield .exe is downloaded and does not open when finished. My internet works fine, but the pop up keeps appearing a few minutes and covers a side of my screen. What can I do?
I use macos sierra version 10.12.6 and google chromeOh and google chrome and kakaotalk(korean messenger app) works fine, but i can't seem to open some apps such as skype and parallels desktop due to no internet connection
