Every time I start my PC, Opera browser launches automatically and directs me to the my website without any input from my end. This repetitive behavior has become quite frustrating, as it interrupts my workflow and consumes unnecessary time. I've checked my browser settings, but I couldn't find any specific configuration causing this issue. I'm seeking advice from the community on how to troubleshoot and resolve this peculiar behavior. Any insights or suggestions on browser settings, potential malware, or hidden scripts causing this issue would be greatly appreciated.

Thank you for your assistance.
