Buffer Overrun detected Rundll32.exe Please Help!

[Kbottles]

Hi, I'm new to this, so I'm not quite sure what I'm supposed to do.

When I start my computer, an error message comes up that says -

"Buffer Overrun detected! Program: C:Windows\system32\RunDLL32.exe

A Buffer Overrun has been detected which has corrupted the program's internal state. The program cannot safely continue execution and must now be terminated"

Then a fewseconds later, that error goes away and another one pops up that says the same thing, except for Explorer.exe as opposed to RunDLL32.exe

If I close either of them, everything on my desktop closes for a few seconds, then returns to normal, and the error message comes back.

I ran HijackThis, but as soon as I ran it, the program said -

"For some reason your system denied write access to the hosts file. If any Hijacked domains are in this file, HijackThis may NOT be able to fix this."

Then a message comes up that says -

"An unexpected error has occurred at procedure: modMain_CheckOther1Item()

Error #75 - Path/File access error

Windows version: Windows NT 6.00.1904

MSIE version: 7.0.6000.16546

HijackThis version: 1.99.1

I continued the scan, and here is my logfile-

I also tried using VundoFix, but after running it, the program said that no problems were found whatsoever.

Someone please help!
