Especially in the registry? I’m often told CCleaner is great for cleaning out my computer, but doesn’t do anything when it comes to malware issues, I need other software for that(I use Malwarebytes, free AVG, Window’s Firewall). However, some security specialists tell me to use CCleaner, as if it has some affect on malware issues, if only on the effect of malware and possibly damage caused by malware, although anti-virus programs do virtually all of the work of protecting and removing. What’s going on?

Okay, I have Windows Vista 64-bit. Very recently, I started encountering two major .dll errors. The biggest error is the ADVAPI32.dll missing error. I get a message telling me the ADVAPI32.dll file is missing. I have checked in System32 and it is still there, at about 1,038kb.

I’ve seen solutions that involve using a registry cleaner but I can’t open the registry cleaners because that file is ‘missing’. Many of programs like Internet Explorer 32bit, Microsoft Word, MSN Messenger, all of my installed games, registry cleaners, anti-virus programs, and probably more programs will not open because of this.

I also get an error message that says ntdll.dll is missing from the ‘dynamic library’ when I try to open other programs.

How can I fix these .dll errors without using a registry cleaner?

Also, I tried doing a system restore from its farthest restore point. It simply will not work. I need a solution please!
Tried bringing up the command line as suggested in answer# 2.

Came up with
RegSvr32:
"The module ‘ADVAPI32.dll’ was loaded but the entry point DLLRegisterServer was not found.

Make sure that ‘ADVAPI32.dll’ is a valid DLL or OCX file and then try again."

My computer will freeze up when I try to install certain software programs. I havent figured out the pattern yet because certain OTHER programs will work just fine!? It will even freeze my computer when I try to install utility programs to run diagnostics on my computer and 3 different anti-virus programs come up zilch. Can SOMEBODY help me!? lol

I downloaded what I thought was a completely free registry cleaner last night… turns out it was a trial. I don't have any money to spend, and I have enough crap wrong with my computer already, so I'm looking for a FREE and TRUSTWORTHY registry cleaner. Any *good* free anti-spyware/malware/virus programs are appreciated as well.
