mfc45.dll corrupted - How do I fix?

I just reinstalled my OS (Vista 32-bit) on my Dell Inspiron 1525. As soon as I was able to get my wireless network working, I re-installed the AVG Internet Security 2011. Upon its initial system scan, it detected that the mfc45.dll executable file (c:\windows\system32\mfc45.dll) located in thewas corrupted. The only option AVG is providing is to remove this file. However, with not knowing what this file is actually for (what bigger picture program) I am hesitant to "remove" it.

I had to re-install my OS because for the last 2 weeks, my system would crash with the "blue screen of death" every night. Looking at the logs, I could not find the "smoking gun" problem. Night before last, however, my system crashed 4 times in 2 hours. That was when I decided to bite the bullet and reinstall the OS. I used the reinstaller program that was available in the System Repair [F8] options.

If I knew where to go to see about downloading a repair for this file, I would...but...

In order to rule out that this is a result of a virus or trojan, I downloaded the Malwarebites program that has been referenced in another forum on this site. It came up with no issues.

Can someone please help me?

It is a false positive, does AVG give you the option to ignore it? You could remove AVG and try Avast, also free.

Its a systme 32 file which makes it a part of your operating system. If you want you can attempt to rewrite by putting the Windows Disk inside and using this command:
expand D:\i386\rundll32.ex_ C:\windows\system32\rundll32.exe
It will rewrite the files

Consider the possibility that your general problems might be hardware related.

Laptops can be fiddling but, for example, your CPU heat sink or fans could be chogged up. If your RAM can be easily accessed, clean the edge connectors with a pencil eraser.

Always pop back and let us know the outcome - thanks
