While a browser hijacker like Me-qr.com might not be as dangerous as certain other types of harmful software, it's still not completely safe. It has the potential to bring about changes you didn't ask for, put your privacy at risk, expose you to harmful web content, and even create other security problems. That's why it's really important to take steps to protect yourself. Make sure you regularly update your browser, use good security software, be careful with what you download and add to your browser, and if anything weird happens, don't ignore it – take action!
