The message I get is the following:

"C:\WINDOWS\SYSTEM32\WRusr.dll is either not designed to run on Windows or it contain an error. Try installing the program again using the original installation media or contact your administrator or the software vendor for support."

I can't open Mozilla firefox anymore. I have tried reinstalling 3 times already.

hello, the file you have referenced appears to be part of Webroot SecureAnywhere - try to remove that software in case you have it installed on your system.

But webroot is my current antivirus. I have had it for over a year and never got any problems. Should i try reinstalling it?

Thanks
