Hidden files + wireless network problem

I recently had another trojan/malware attack. It didn't go far before I nipped it (think I got them all), but either they, or the cleanup, left my hidden files system compromised, which is why I'm posting the question here.

In particular, even though I choose the 'display hidden files and folders' option, they still remain hidden. Attached is a pic/s that show an example of this problem + my folder view settings.

Top left: The G:\ drive appears empty.
Top and bottom right: My 'Folder Options -> View' settings.
Bottom left: Pop-up window when I Press Ctrl+A (select all).

This happened to many important folders including 'C:\Windows\System32\drivers', but some of them I got back using command prompt (attrib -h "[folder path]" or something like that).

Also, my wireless network connection has stopped working, or more specifically I cannot start Windows Zero Configuration utility. More on that later (need to recheck it again after I post this).

Thanks in advance.

 

Here are the logs.

 

I ran Malwarebytes' Anti-Malware and it found 0 infected files, and detected no malicious items, but I can't post the requested log file because this forum won't accept it. [See the print screen pic if you want.]

 

Yes.

Yes.

Yes. No hidden files there anymore as far as I can tell, but that's only after I used command prompt to unhide my drivers folder.

G: is an external hard drive, but the problem has presented itself elsewhere. I just tried to find another example, (I checked 'Application Data' folders, for example, where it happened before), but couldn't find any, so maybe the problem went away.

The only changes I'm aware of are that the scans you requested deleted some IAM-folder, disabled my fingerprint logon program, and subsequently I disabled my Windows logon password since it was a PITA to keep typing in my password manually instead of just wiping my finger over the fingerprint scanner as before...

It's part of the HP's security system that came with the laptop. The fingerprint scanner may be part of it, or related at least. The programs you asked me to run may have disabled it. HP used to store all my passwords somewhere, and it would ask for a fingerprint, and input the passwords whenever I entered an email or message board website. For example, when I came to forums.majorgeeks.com, it would ask for my fingerprint, and then log me on, but that has stopped now. I assume I can restart the program manually, but I'll wait until my current problems have been sorted before I do anything about that.

Does that help?

 

There's no problem with drive G:. The 2 hidden folders were "RECYCLER" and "System Volume Information" (I assume); at least those 2 now appear when I look at G: and I don't get the error message anymore when I 'select all' in that drive or any other directory. Whatever those scans did, they fixed the problem - maybe it was something to do with HP's fingerprint/password authentication and protection.

Thanks for the help so far. I'll get back to you on the other things later. I still have the wireless problems that also coincided with the Trojan attack, but I'll post more about that tomorrow (need to test it again and take some 'print
screen' pics first.'

 

Wireless problem:

I'm currently using a cable connection, but need my wireless back (currently same provider as the cable) for when I leave home.

When I turn it on (at home), it links to some random networks if at all. I try to select my own secure Verizon network, but I cannot view the list of available networks (Windows cannot configure them), and I cannot start Zero Configuration utility either. The exact messages I get when I try are show in the attached pics. I've tried the usual things, but without success.
