sprote~1.dll looks suspicious to me. No version information, no digital signature. Sophos detects it as "Mal/Behav-034".

Anyone have some more info on the sprote~1.dll file?

sprote~1.dll is related to

sprotector 1.62

I suspect they are malware.

I had an issue with all 32 bit browsers not opening but IE 64bit worked fine. Resolved issue after uninstalling them.

@g.kibria: Some of the anti-virus programs detects sprote~1.dll as a trojan, so I think it should be removed.

You can either delete it manually in Explorer or use the FreeFixer tool to delete it.

Did that solve the problem?
