From 2-spyware.com
Mycoolfeed.com – the program considered to be a redirect virus because it shows third-party ads and commercial content trying to trick people into allowing additional notifications. Adware[1] can be involved in various revenue-generating campaigns, so the program is not malicious, but the content delivered might be. Since the infiltration most likely happened behind your back while other programs were installed, you cannot know which one is the PUP that triggers all the slowdowns and other behavior. If you do not encounter any system issues, you might not even have the intruder on the machine, so you need to stay away from this site completely and avoid additional installation. If redirects reappear all the time and you see system problems – rely on AV tools and remove the PUP.
