Hello; please note I am not a staff member here
, but perhaps I can help get things started.
Those pop-ups and warnings definitely aren't from legitimate programs. They're often nicknamed "scareware" because they try to scare folks into downloading or even paying for their software, which just makes things worse.
Also, when I checked "My Computer" is shows a software program I have is HijackThis 1.99.1 I have no idea what this is.
HijackThis is an advanced scanning tool that can show suspicious entries on your computer. It shouldn't be there unless someone purposely installed it, though. Has someone else been working on your machine, or did you get this computer recently? Or was HijackThis not showing up in "My Computer" before now?
Also, do you have an antivirus program already running, and if so, which one?
The first thing I'd suggest is installing and running Malwarebytes' Anti-Malware, which is fairly simple and can do a great deal of cleaning right away. It may take a few hours to run. If you have any questions about running it, please post back here and we'll help out.
