My web browsers both firefox and chrome have been hijacked by cassiopesa malware.
I think this was downloaded when I was updating cc cleaner and firefox noted that I needed to update flash player, I started to do this and something didn't seem quite right with installation so aborted.
I updated both CC Cleaner and Malware Bytes and have run both. Malwarebytes picked up the casiopese and quarantined.
When I opened firefox for the first time after running malwarebytes an address appeared in address bar with cassiopesa in it although this has now disappeared.
However I am unable to now access internet and get error message 'firefox is configured to use a proxy server that is refusing connections'.
I do not know how to resolve this, can any one advise?
Thank you
gom
ps. I have found that if I change network settings from 'use system proxy settings' to 'auto detect proxy settings for this network' I can connect to the internet but am concerned that this is still compromised by malware.
