Pls Help, Cannot up-date antivirus database

I just download and install comodo firewall+anti-virus. When i start program comodo says that anti-virus database was newer updated. So i try to update anti-virus, on 5% download progress comodo says that me is not connected to INTERNET. Please HELP!!!

May be left overs of previously installed security programs are in the way. Try using removal tools for those programs. Here is a list of removal tools for common av programs: ESET Knowledgebase .

Otherwise do a Google search with terms “removal tool” and * name of product or vendor*.
