I'm having a very strange problem with a customer computer.
The problem started that he couldn't send e-mail through outlook. He got the 0x800ccc0f error. I told him to reinstall Norton Antivrus 2005, but then he also got the same error when receiving e-mail. I uninstalled Norton 2005 again and deleted all folders in application data folder etc containing Norton stuff... Without Norton I could send and receive e-mail. After installing it again and after running all updates from Symantec the problem was not solved. I also recognized that I was not able to send e-mail via web mail! I logged on 3 different web mail accounts on three different servers in two different countries! When clicking send via web mail the status bar just raises slowly until I got “page cannot be found”.
I uninstalled Norton and installed NOD32, then I could receive e-mail and I was able to send e-mail as long as I had no attached files. I will continue to investigate this today.
Is it a virus?
