I got Windows defender popped up this error code 0x268d3 and told me to call a number for help. What is this message? Is it safe to call the number?
I turned off my router, all computers, cell phones, and devices to the router. Then, I just turned back on this computer and ran Norton Power Eraser. It found one file that has virus. The file name is called something like system64/WOW... I deleted it and turned back on all the devices to router. My computer is working as normal.
Do I need to take care other things? Thanks for any recomdation.
