HijackThis and MalwareBytes won't run

[OcarinaMaker]

Hi!

I'm trying to help my mother with her laptop. Windows Media Player and other apps will no longer run. If I right-click "copy" a file/folder, "paste" is no longer an option in a right click menu. I can't access "Users" in Control Panel.

Avast had not been updated in a while as she is on a dial-up and doesn't really go online much. Avast would no longer run. I downloaded it to a connected computer and moved it (and some other anti-malware apps, inucluding MalwareBytees with newest rules) to the seemingly infected computer using a flash drive. I was able install and run an Avast scan, which did remove 3 incidents of Win32 tro-gen.

I did a registry repair and rebooted.

I tried to install Dr.Web CureIT, which ran a scan and reported that it moved infections into quarantine, but didn't give me a report.

I tried to install and run MalwareBytes and started getting this error: "Failed to load control 'vbalGrid' from vbalsgrid6.ocx. Your version of vbalsgrid6.ocx may be outdated. Make sure you are using the version of the control that was provided with your application."

I followed the instructions in this thread, http://www.malwarebytes.org/forums/index.p...amp;#entry34171, but I get an error when I try to run "SubInACL" and the .bat returns with errors in the command line too: "subinacl" is not recognized as an internal or external command."

Spybot installs seemingly with no problems and I added the latest rules as well, but then when I attempt to run it, it begins the scan then disappears. Same thing happened when I installed and ran HijackThis. Now neither will even open a second time.

I can't log out and switch users to the other Windows user account...just keeps flashing back to the login/Welcome screen.

I don't have a copy of Windows XP up here at her house. I just stopped by for a day visit on my way home, which is a 4 hour drive away. Otherwise I'd simply wipe it all out and start with a new Windows install.

Can you help at all?

Thanks so much for any help you can offer, Barbara

I want to add that after I wrote the last post, I installed and ran Combofix, which reported that it found a rootkit and deleted/repaired a couple of files, but all of the problems are still there. In addition, it did not create a log that I can find.

I am unable to copy and paste anything, or drag and drop, so anything I run must be run from my USB flash drive.

I'm reluctant to connect it to the Internet and even if I did, I'd have to use her bad dial-up connection.

Thanks and best regards, Barbara

Welcome Barbara

Put a feshly downloaded copy of combofix on a usb stick and run it on the infected PC while it is in safe mode.

If combofix restarts the PC boot back to safe mode, when the log opens close it and restart to normal mode then post

c:\combofix.txt please
