Is it still acting funny at boot? Did you get the permission error again when you last ran Combofix? If so:

Let's try resetting the registry permissions to the defaults.

Download SubInACL.exe

http://www.microsoft...&displaylang=en

Right click and Run As Admin to install.

By default it installs the tool in C:\Program Files\Windows Resource Kits\Tools\

Please allow it to do so.


Download and Save the attached file, reset.zip, right click on it and Extract all and copy the reset.cmd file to C:\Program Files\Windows Resource Kits\Tools\.
Start, Run, cmd, OK Type with an Enter after each line:

cd  "\Program Files\Windows Resource Kits\Tools"

reset.cmd

After running the reset.cmd, there's no more blue screen on Windows boot up, but I did get a notice saying a program is attempting to stop Avast from running and it gave me the option of a Yes/No to allow it to or not. I said No.

I've also had 2 warnings about my recycle bin being corrupt

Do you think there could still be traces of malware on my system or is it appearing clean?

I don't see anything but I can't see everything and I'm not sure why your Recycle bin is having problems. Is your Avast up to date? (Right click on the Avast ball and click on Update then on Engine and Virus Definitions. It should either update or tell you that it is up to date.) If it appears to be working now then I would have it run a boot-time scan tonight and let it run while you sleep (I'd mute the speaker so it won't wake you up when it reboots):

Click on the Avast ball. Then click on Scan Computer, then on
Boot-Time Scan then on Settings. Change the Ask at the bottom to Move to Chest. OK then Schedule Now. Reboot and let it run a scan. It will take hours.
Once it finishes it should load windows. Click on the Avast ball and then on Scan Logs, select the Boot-time scan report then View Results. How many did it find?
Text version of the report is at: C:\ProgramData\Avast Software\Avast\report\aswboot.txt

Manually delete the following files:

K:\data files\zcs70101\zwt.rar

These don't follow the rules for zip and rar so won't work right anyway.

or we can do it in OTL:

Copy the text in the code box by highlighting and Ctrl + c


:files
C:\Autodesk\Maya_2013_CEJ_Win_64-bit\x64\DirectConnect\DirectConnect7.0.cab
C:\Program Files\Common Files\Autodesk Shared\DirectConnect2013 (64-bit)\Public\DevIL\DevIL-1.7.8.zip|>devil-1.7.8\configure 
C:\Users\Administrator\AppData\Roaming\Apple Computer\MobileSync\Backup\e231cb939f428ee144f2dc72f03349e6c9a2125c-20100605-093326\e06469f8ae60cdc7f406b8e6cfe5576169cb0d93.mddata
C:\Users\Administrator\AppData\Roaming\Apple Computer\MobileSync\Backup\e231cb939f428ee144f2dc72f03349e6c9a2125c-20100605-094412\e06469f8ae60cdc7f406b8e6cfe5576169cb0d93.mddata

K:\data files\zcs70101\zwt.rar

then Rightclick on OTL and select Run As Administrator to start. Under the Custom Scans/Fixes box at the bottom, paste (ctrl +v) the text. Verify that you got it all and Then click the RUN FIX button (NOT THE QUICK SCAN button!) at the top
Let the program run unhindered,

Let's look into the Recycle Bin and see if there is anything hiding there tho I would expect Avast to find it.
copy the next line:

dir /a c:\$Recycle.Bin /s > \junk.txt


Start, All Programs, Accessories, right click on Command Prompt and Run as Administrator, Continue. Right click and Paste or Edit then Paste and the copied line should appear.



Hit enter. Attach c;\junk.txt to your next post.



You might want to check your RAM to make sure it's OK:
http://www.howtogeek...iagnostic-tool/

You could also be having early symptoms of hard drive failure. Go to the maker of your hard drive's web site and look for a drive test program. Usually the Quick test will pass but sometimes the Extended test will find something.

RAM check came up 'No problems detected'

Used SeaTools for my boot up Samsung Seagate HDD, using the 'Long Generic' test, which it passed. There was an option for Advanced Tests (but it noted it could erase data so I didn't look into it further)

What made you suspect possible hard drive failure? the Recycle bin being corrupted? or something else that you noticed?

What made you suspect possible hard drive failure? the Recycle bin being corrupted?


Mostly that plus the corrupted downloads and the odd things that happened with Combofix. Appears we can rule that out. How is it running now? Any problems?

hmm I'll keep an eye out for any other strange HDD issues but everything else seems to be running ok at the minute Ron. Is there anything else you'd like me to run?

I think it's clean up time:


We need to cleanup System Restore:

Copy the following:

:Commands
[CLEARALLRESTOREPOINTS]
[Reboot]

Right click on OTL and Run As Administrator. In the Custom Scans/Fixes box at the bottom, paste in the copied text (Ctrl + v) and then hit Run Fix.

That will get the last of the malware off the system.



You can uninstall or delete any tools we had you download and their logs.
To uninstall combofix, copy the next line:

"%userprofile%\Desktop\combofix.exe" /Uninstall

Start, All Programs, Accessories then right click on Command Prompt and Run As Administrator.
then right click, Paste, then hit Enter.

OTL has a cleanup tab if you go there it will remove itself and its logs.

To hide hidden files again (OTL may do it for you):

Vista or Win7

# Open the Control Panel menu and click Folder Options.
# After the new window appears select the View tab.
# Remove the check in the checkbox labeled Display the contents of system folders.
# Under the Hidden files and folders section select the radio button labeled Do not Show hidden files and folders.
# Check the checkbox labeled Hide protected operating system files.
# Press the Apply button and then the OK button and exit My Computer.

Also make sure you have the latest versions of any adobe.com products you use like Shockwave, Flash or Acrobat.

Whether you use adobe reader, acrobat or fox-it to read pdf files you need to disable Javascript in the program. There is an exploit out there now that can use it to get on your PC. For Adobe Reader: Start, All Programs, Adobe Reader, Edit, Preferences, Click on Javascript in the left column and uncheck Enable Acrobat Javascript. OK Close program. It's the same for Foxit reader except you uncheck Enable Javascript Actions.

To help keep your programs up-to-date you should download and run the UpdateChecker:
http://www.filehippo.../updatechecker/
(You don't need to download Betas and if there is a program you don't use you can just uninstall it rather than update it. Exception is MSN messenger which appears to be part of Windows.)
If you get a blocked program notice after installing updatechecker then change it to not run at start then manually run it once a week.
Seems to work best if Firefox is the default browser. You can also try Secunia PSI http://secunia.com/v...l/download_psi/ Same kind of info. You don't need both.
If you use Firefox then get the AdBlock Plus Add-on. WOT (Web of Trust) is another you might want to try.
The equivalent to AdBlock Plus for IE is called Simple Adblock and you should install it too: http://simple-adblock.com/
The free version only blocks 200 ads a day so another reason to use Firefox or Chrome.

If Firefox is slow loading make sure it only has the current Java add-on. Then download and run Speedy Fox.
http://www.crystalidea.com/speedyfox . You can run it any time that Firefox seems slow.

Be warned: If you use Limewire, utorrent or any of the other P2P programs you will almost certain be coming back to the Malware Removal forum. If you must use P2P then submit any files you get to http://virustotal.com before you open them.


If you have a router, log on to it today and change the default password! If using a Wireless router you really should be using encryption on the link. Use the strongest (newest) encryption method that your router and PC wireless adapter support especially if you own a business. See http://www.king5.com...-120637284.html and http://www.seattlepi...ted-1344185.php for why encryption is important. If you don't know how, visit the router maker's website. They all have detailed step by step instructions or a wizard you can download.

Special note on Java. Currently there is an exploit out that works on all Java Version 7 software so we are recommending that if you do not visit websites that absolutely require Java that you turn it off in your browser per the instructions in http://www.geekstogo...ur-web-browser/
If you use websites that require Java and you trust them then we recommend that you use either Firefox with the NoScript add-on or Chrome with the ScriptNo add-on and avoid IE. NoScript/ScriptNo will turn off Java and Javascript on all websites you visit except for those that you specifically approve. More info on the exploit is here: http://krebsonsecuri...y-java-exploit/
A new Java 7 Version 7 was released on an emergency basis to fix the exploit but apparently actually makes things worse.

My help is free but if you wish to show your appreciation, please donate to Kwiaht instead of me. It's a local environmental organization that I volunteer with: http://www.kwiaht.org/donate.htm
(The name means something like "clean place" in one of the local native-American dialects)
