A lot of nasty problems: games.sms591.com sms591 ringtone adware can't get rid off, BitComet auto shut off, unable to view hidden files, iedw.exe error, SysAd2, SysAd3, Ghook.dll, svchost.exe

Hi, my sister's laptop constantly have problems. This time there are several nasty problems, any suggestions and help will be greatly appreciated!

Here are the problems:
- games.sms591.com & sms591.net ring tone pop up: this ring tone web page always opens up an IE window from time to time.
- BitComet auto shut off: it is fine to start up. I can load up Bit Comet fine, but as soon as I click anywhere in the BitComet window, it will close itself off. Close itself off as it didn't minimized, the whole program bitcomet.exe gets shut off from the Windows Process List.
- Unable to view hidden files: every time I select view hidden files, no hidden files will be shown up at all. And as soon as I go back to the options to select view hidden files, it is always the hide hidden files option being checked.
- iedw.exe error: I have no clue what iedw.exe is. I don't even think my sister has such a program at all as she only knows how to surf (mainly Chinese news, celebrity sites). The error message says:
iedw.exe - Application Error
The applicateion failed to initialize properly (0xc0000142). Click on OK to terminate the application.


Here is what I have done:
The games.sms591.com & sms591.net ring tone pop up, I have tried the methods that are mentioned in this site: http://blog.cersp.com/userlog19/48446/archives/2007/254282.shtml (sorry it is a Chinese site)  I haev used Sreng2 and done what it said in the site. With the exception that I can't seem to find similar numeric .EXE or .DLL files that have been mentioned on the site (not sure if they are hidden or what)

For the Bit Comet, I have tried to uninstall and reinstall, but the same problem still exist. Bit Comet problem seems to happen after I installed AVG. Though, even after I removed AVG, the same problem still exits. (reinstalled to do scan)

I used Ad-aware and removed infected files that it has found (over 140).

I have also used AVG scan. Did find a lot of infected thing, I have deleted all. But it can't seem to find sms591.

Also, used Security Task Manager. I have removed a lot of weird programs, but still these seems to coming back:
Ghook.dll C:\SysAd3\Ghook.dll
Ghook.dll C:\SysAd2\Ghook.dll
svchost.exe C:\SysAd2\svchost.exe
svchost.exe C:\SysAd3\svchost.exe
Here is the screenshot that I have took. One shows up 100 rating, and the other shows 57 rating.

I have tried to locate those files, but I can't find them. So they are probably hidden files I assume. But as I have mentioned, I can't view hidden files.

Also done a HijackThis log, this is the log:

Also when I open Windows Process List, sometimes I will find a lot of random unknown programs running, like.. winlog0n.exe and other weird named exe programs.

Any help or suggestions on how to solve these problems will be greatly appreciated. If you need any more information or need more explanation or details, please feel free to tell me.
I apologize for the long post.
Thank you very much!
