I should note that my Lenovo had its battery in and power cable connected. It was also hooked up to a wireless logitec keyboard, a usb cable mouse, and monitor via an old multi-pin hdmi cable at the time of the problem.

Hello, a few hours ago my laptop suddenly froze and started behaving in a way that I've never seen before and I believe something has compromised my security.
Before the incident I was working on Microsoft Word 2013, had google chrome with 3 open tabs, (which consisted of 2 Rutgers University links and this link that had 3 streaming music playlists for studying. ), and was running a system scan on my antivirus.

I then started up OriginPro9.1 which is a data analysis and graphing software. As soon as I clicked on it the CPU/RAM monitoring widget I have on my desktop spiked its CPU usage to over 50% and even hit 100% multiple times (which is far more than it has ever gone up in the past, even with chrome, word, and origin open simultaneously). It continued to fluctuate between 1% and 100%
Then I couldnt exit out of any programs and the screen eventually turned completely black except that I could still control my mouse pointer. I tried to force quit but nothing happened. Then after a few minutes I got a popup on the black screen that said something about a logon error and that i should hit [esc] or turn the laptop off manually if [esc] didnt work.
Eventually some grey desktop background appeared, along with my taskbar and CPU meter. I still had no control of the system. Lastly, my own desktop background reappeared only without the taskbar. I waited some more and then the process started repeating itself in the exact manner I just described. After I sat through 2 complete cycles of that, I shut off the laptop and booted up again. I would have shut off the laptop much sooner but i didnt want to lose my word document that I had yet to save.

Strangely, throughout the entire duration of the crash, the music i was streaming never stopped playing as well as the CPU meter continued giving live data.

Ever since I rebooted, having as little as a single tab on chrome open spikes the CPU usage over 35% along with my RAM consumption periodically increasing from 40% to 65% and is still rising... I've run several full system scans with my internet security/antivirus program that I just payed $50 for a couple weeks ago and no threats come up.

I'm at a complete loss about what happened and what I should do, and I really need some help. Thank you.
