When I type (management 0/0) ASDM site and will promt to install ASDM but after entering the username and password there is a message malformed.

There is no issue with firewall.. You need to check your JAVA version.

I hope there is some issue with your java installation on your local pc

What version of ASDM you are running? Depending upon the Java compatiblity could change. Here is a document that outlines Java requirements for 6.0(3) ASDM version.

Similarly, every ASDM version will have such compatibility information. I would suggest you look into those and check your Java version.

Hope this helps.
