Corrupted file C:/Windows\SysWOW64\mfc45.dll

My AVG scanner keeps finding a corrupted file called C:/Windows\SysWOW64\mfc45.dll I've had a look online, but no one is clear about this. AVG detects it and moves it to virus vault, but it keeps coming out every time I do a scan. I have also tried to remove it with FreeFixer, but it keeps coming back. Does anybody know what it is and if it's dangerous or if it is a false positive?

Hi There Andrea,
Thank you for contacting AVG! i have done an hours research on mfc45.dll and i can see nothing to indicate that this is a Virus.

MFC45.dll does not seem to be tampering with your computer in anyway from what you have said so what i would personally do is add the file to exceptions and report the file as a false positive.

To add the file to the exceptions you can follow the YouTube guide here: https://www.youtube.com/watch?v=LdkSDR5W_JI (https://www.youtube.com/watch?v=LdkSDR5W_JI" target="_blank)

To Report the false positive you can visit the submit sample page located here: http://www.avg.com/submit-sample (http://www.avg.com/submit-sample" target="_blank)

Regards,

Kenza

Hi Kenza,
Thanks for your quick reply. Other forums report this as a malware, are you definitely sure that it will be safe to add this file to the exceptions?
Thank you

Hi Guys big thanks for confirming this is not a problem, I have seen this come up on numerous PCs with window 7 64 bit using AVG, there are alot of sites suggesting it is a problem and i figured it could be a registry issue but after running all efforts to repair including the sfc scan i was stuck as sfc never noticed the error and i could see no actual reports of issues in the admin tools, has settled my mind now as usually when i encounter a problem i usually can fix it. Just wish everyone else knew lol pooor sods trying to fix an issue which is just a false report

Trojan.Valyria is also a variant of Trojan which posses worst impacts on the system performance.

Updating all of you about mfc45.dll
First of all, it is not a core MS file at all. It doesn’t come within the MS package or anything else. I even didn’t found any such file within my Syswow64 folder in my MS Windows 7 installation drive.
I learned about this over Microsoft official website and other popular websites such as www.fixinfectedpc.com and www.nowremovevirus.com as well.
