For the most part pretty well; however, occasionally a warning message will pop up saying something about a script isn't working right and will ask if I want to continue running it. Regardless if I select yes or no, another message will pop up saying my system is compromised. This error message covers my whole screen and no matter how many times I push "OK" it continues to pop up. Also, my computer makes a loud beeping noise while this second error message is on my screen. I've run the Zemana AntiMalware program, but it tells me my system is clean.
