mfc42loc.dll appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts.

For this reason, 79% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.
If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant.

With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.
