When I Enable the Proxy for the Record A on infu.xyz I was unable to Access My Website’s Dashboard, please help me to solve this issue.
When I tried to open your Website with IP 103.xx my Malwarebytes Anti-virus software stopped and blocked the request.
I wonder if you have some malicious code or malware script on your Website which might result into this 
I am afraid Cloudflare isn’t involved into this.
However, may I ask if this behaviour continues even when Cloudflare is in “Pause” mode for your domain?
You could determine if this behaviour continues even by using a “Pause” option at Cloudflare as follows:
- Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
- The link is in the lower right corner of that page.
- Give it five minutes to take effect, then make sure site is working as expected with HTTPS.
- Re-try with updating.
- Upon success, un-pause and continue using Cloudflare.
May I ask have you tried using a different Web browser, or tried clearing your Web browser cache?
How about using a Private window (Incognito mode) or a VPN connection if possible?
Is it the same behaviour on your mobile phone (4G LTE, mobile data, cellular)?
