Getting an error message about a missing file when I try to open Firefox

more options

When I tried to open Firefox today I received a message about a missing file (Wrusr.ddl) and that Firefox was not able to open. I tried uninstalling and reinstalling but it did not work. I have no idea what that file is or where is went. I used Firefox 2 days ago and it was working fine. The only thing that changed between then and today was that I renewed my antivirus software but I definitely did not delete any files and I made sure that Firefox is allowed to access the internet. I've been using that same software (Webroot) with Firefox for years and never had any issues before today. Any help would be greatly appreciated! I have included a screenshot of the error message below.

hello angelag.132, the WRusr.dll file is part of Webroot SecureAnywhere - try to reinstall or uninstall that software.

Thank you for responding so quickly Philipp! This is probably a stupid question but Webroot is not showing up in my program files under control panel for me to uninstall it and when I find the actual program on my computer there is no uninstall option. Should I just delete the program (i.e. send to recycle bin then permanently delete) and try to reinstall?

That did the trick. Thank you so much! I tried manually uninstalling via another solution on Webroot's site first but it didn't work. I must have missed the article about the clean-up tool on there. I really appreciate the help Philip!
