Steam will not update or download games. They said it was my antivirus software. How can I fix this

Until recently I did not have a problem.  Suddenly I cannot update or download game content from Steam.  The Steam App reports an error "missing content manifest."  The only thing I have been able to get from looking at the Steam site, is that the problem is related to my anti-virus/firewall software.

Hello ?
Welcome to the Webroot Community,
Please have a look here at these PC User Guide articles that can help you with unblocking and allowing if you are totally sure these programs or sites are not malicious.
Controlling active processes
Blocking/Allowing files
Managing protected applications
(If your OS is Windows 8.1 or Windows 10 please look here
Lets try to put into English the essence of the areas where a user can tailor what WSA does to protect the system
There are essentially 3 key areas where this can happen/a user can override WSA.  These are essentially reached, from the main WSA panel, as follows:
  1. PC Security > Block/Allow Files
  2. Identity Protection > Application Protection
  3. Utilities > System Control > Control Active Processes
and once there the user usually has the options to:
A. "Allow"
B. "Protect/Monitor"
C. "Block/Deny"
In the case of 1. Detection Configuration
If an item is set to:
- "Allow", WSA ignores it during scans and shield actions, meaning if it's a virus that has been allowed, it can continue acting as a virus acts.  Be careful of what you allow in this area and ensure it's something you trust implicitly if you are going to change the status from Block to Allow.
- "Monitor", WSA will watch the item to determine if it is legitimate or related to malware.  It is not necessary to add files into this list or set files to monitor manually unless you are changing them from a Block or Allow status.  This might be useful if for example you think Webroot might have had a false positive on something and you want to check again at a later time to see if the determination has changed.  You could set it to Monitor and have Webroot check it again.
- "Block", then WSA will treat the items as it would detected malware.  It will not be executed, and it will not be written to your hard drive.  Detected infections are automatically set to a Block status.
In the case of 2. Protected Applications (Internet Security & Complete version ONLY)
In this case:
- "Allowed applications" are not secured against information-stealing malware, and also have full access to protected data on the system. Many applications unintentionally access protected screen contents or keyboard data without malicious intent when running in the background. If you trust an application that is currently marked as "Deny," you can change it to "Allow."
- "Protected applications" are secured against information-stealing malware, but also have full access to data on the system. By default, web browsers are assigned to the "protected" status. If desired, you might also want to add other software applications to "protected," such as financial management software. When you run a protected application, the Webroot icon in the system tray displays a padlock.
- "Denied applications" cannot view or capture protected data on the system, but can otherwise run normally.
And finally, in the case of 3. Control Active Processes
If a process is set to:
- "Allow" it means WSA allows it to run on the system. It's important to note that if an item is already allowed here, that's because Webroot knows already from seeing the file before that it's ok to allow.
- "Monitor" status means WSA will journal what that program is doing and keep a very close eye on it for any suspicious activity.  Basically it would treat it as if it wasn't already sure about it one way or the other, and it wants to monitor it closely until it's sure about it.
- "Block" means just that...iWSA does not allow it to run on the syste.  Be very careful about what you block in this area and ensure that anything you decide to block is a non-essential process.  Otherwise, you could be setting yourself up for a lot of grief if you block something critical.
Now, hopefully that has given you a consolidated low down on where to look and what you can do to affect how WSA 'interferes' with files, objects & processes on your system...and so wil help you get to the bottom of what is causing you grief.
I'm having the same issue and adding C:Program Files (x86)Steamsteam.exe as allowed in all three sections makes no difference.  I've looked and don't see any other steam application that is being blocked.  The only way to allow downloads is to either disable the webshield or close webroot completely.  This only started happening in December of last year, befopre that I had no issues with webroot and steam.
