Hi Wangcm, welcome to the community! Thank you for posting. 

Sorry to hear of these issues with your email access! If you have received this message one of our systems has identified suspicious activity happening in your email account. 

In the first instance I would recommend you have a quick look here: My Virgin media email has been hacked and ensure you have followed all the steps to secure your account. 

You can also see here for general support on managing your email account: How to manage my email account. 

You have done the right thing in performing a virus scan and trying to update the password - did you change this to a completely new, unique and secure password? If the password is associated with any other accounts we would recommend that you update this to be a unique one for this email alone. 
We would also recommend updating your secondary email security information (Ie your memorable word and reminder questions) to ensure a secondary layer of security. 

Please let us know how you get on following this! We will then offer further support if needed. 
All the best.

Strange that:
Now on my mobile phone I have received a few emails to this blocked address and I can send replies seemed OK. But on my laptop when I tried to open my mailbox I got a "Forbidden" page!
