Answer #1
looks like you got that nasty fake antivirus program which loaded on your computer!!
i recommend that you download malware antimalwarebytes, not unless you got it already, and do a scan of your system and see what it finds.
also take a read here and it will tell you more about it and how to remove it.

Firstly install malwarebytes (link is given above) and make a full scan with it – it will remove this annoying fake antiviruses and fake googles. After that you have to increase your security measures. If you don’t know how to do that, check the following link:
