won't allow any downloads and has no restore point

I found recently my computer stopped allowing downloads of any kind and also gets an error message if I try to restore to an earlier time. Also says some of my programs are not compatible with my system?? This computer I bought new 2 years ago, Dell all in one Inspiron One?

  1. What operating system are you using?

    What antivirus and/or antimalware are you using, if any?

    What programs does your computer claim aren't compatible?

    What changes have been made (think installing programs or downloading suspicious email attachments) in the time period around when this issue started?

    Sounds like malware, maybe a virus, boot into safe mode w/ networking and run Malwarebytes
