"System Status" is not leting me "update now"

Comodo is not allowing me to “Update Now”… I think my system is infected, please help.

Which version of CIS do you have? Is it 3.13.xx… 581 or 586?

AFAIK, for other earlier versions, Comodo has stopped virus updations. If it is an earlier version, update to new version either by clean install or Open CIS-Miscellaneous-Check for Updates

Problems do occur in ‘submit files’ using CIS’s GUI interface. However, you can send suspected / False Positive files using the following link and necessary action will be taken by CIS lab.

May be servers were not responding. Does trying again help?

You can get the installer of the latest version in COMODO Internet Security 3.14.129887.586 released.
