hi Zebra, your machine seems to be infected with some kind of virus now. luckily, if this is the case, there is ample information on the internet to, in most cases, manage this directly.
at this point, you can either seek professional assistance or try to manage it yourself but without action, this will continue to be an issue. failure to address this issue could result in permanent damage of your machine..in most cases, the symptoms are just indications of a progressively worsening issue.
i'm not a security professional and not suggesting you do anything specifically, but ((""IF YOU HAVE A PC")(if you don't, i don't have any experience withit- ignore the following quasi-suggestions and consider seeking additional help))
To start, it could help to update the security applications delivered by your OS, then run those programs. IF that doesn't work, I've also had good luck with downloading and running
https://www.malwarebytes.com/
If you are still bork'd, which I'm guessing you will be, you could try going to here
https://sourceforge.net/projects/hjt/ and follow the information on this website.
After reading a bunch, following the steps.. following more steps, literally hours for a bork'd machine.. you should be able to identify the malicious programs that have loaded themselves into your 'registry' and have the tools to eliminate them.
I haven't had to employ this process for years, so I can't give too much info on the newer versions and info but again, read, learn and clean.. or pay someone to do it, if you can afford it. Again, I'm not an engineer, I just know a little more than you do right now, from reading and hours spent. Read up and beat this thing.
If you have smart tech friends, you are lucky. Make them do it. Bribe them with good food or other things.. I would swear that everyone loves glazed donuts. if not, you will have to do it by your onezies, or shell out some duckets to another. it may also be the case that you need professional help, regardless of your efforts.
from my experience, cleaning infections is a process. once you know the process, in many cases, you are golden and golden is super bueno. i wish i could help more but I'm just a fuzzy jabbering sales monkey, who usually tries to be helpful, but sometimes gets it wrong.
