System Halted after installing software for Netgear Router

I have recently installed a Netgear router onto my Windows 98 Acer laptop. One day after, while I was so busy playing my favorite online game, this disgusting error had appeared on the computer screen saying “Windows Protection Error.
System Halted” and it required me to restart my computer.
Of course, I didn’t think of restarting my laptop just because of the error until I realized that it already gave me an irritating situation.
Is this concern somewhat related with virus protection and the Netgear router that I had installed? Currently, I am using McAfee Antivirus Plus and it does not detect any virus on my computer.
How can I fix it? I would really appreciate a little help. Thank you so much.
