Computer still slow after removal of "Data-Recovery" Malware

Posted on 2011-09-25
Last Modified: 2012-05-12
I recently removed the Malware that infected my computer called Data Recovery. My computer is still responding extreamely slow. It's also playing music or radio station without any player running. (It's hearing things!!)

I ran Combofix on it. Can someone take a look at my log file for me please.  combofix.txt

Detailed instructions for properly removing the "Data Recovery" variant are here:

If you have problems using the recommended rogue process stopper (Rkill) you can try using "RogueKiller" instead.

I assume that is a fresh download of combofix? If not then download a fresh copy and run it again.

You could also try running Kaspersky's virus removal tool.

Yes, that was a fresh download of combo fix. I've ran McAffee anti-virus and it didn't report any problems. Do you think I should try again with Kaspersky?

The system may still have some nasties that combofix didn't detect so I would try running Kaspersky virus removal or at least another scanner to check what the other scanners have missed.

You can also run OTL.exe, this one is a diagnostic tool and won't delete anything without a script but will generate a logfile that we can check.

Download OTL, save to Desktop or other convenient location.
OTL does not need to be installed, simply click the OTL icon to run
Click the Quick Scan Button.
Post/attach the log here.

I ran OTL and attached the two logfiles that it generated.

I also re-ran Malwarebytes and it found two things and I had it fix them. I'm going to download Kaspersky now and run it if I can. It's sooooo slow.

I downloaded Kaspersky and attempted to run it. It required me to remove McAffee, after I did that Kaspersky would not run. It says checking the computer for threats before installing, and it does that for hours.
Is there a virus scan that I can run from the internet that doesn't require installation, that could possibly avoid the block that is causing Kaspersky not to install.

Do anyone else have any suggestions that could possibly help me?

Every scanner that I try to run crash. I've tried Norton Power Eraser, tdsskiller, Kaspersky, Malwarebytes, Clam Win AV, Trend Micro AV. I just don't know what to do.

Apart from a lot of unneeded programs there can't see any obvious malicious entries, if there is then it's stealth maybe also try Gmer..

Also Run OTL to remove these ADS.
Under the Custom Scans/Fixes box at the bottom, paste in the following

[2006/01/13 00:33:53 | 000,031,744 | ---- | C] () -- C:\Documents and Settings\Mrs. Hall\Local Settings\Application Data\DCBC2A71-70D8-4DAN-EHR8-E0D61DEA3FDF.ini
@Alternate Data Stream - 160 bytes -> C:\Documents and Settings\All Users\Application Data\TEMP:DFC5A2B2
@Alternate Data Stream - 152 bytes -> C:\Documents and Settings\All Users\Application Data\TEMP:C39E55C5
@Alternate Data Stream - 127 bytes -> C:\Documents and Settings\All Users\Application Data\TEMP:1CA73D29
@Alternate Data Stream - 102 bytes -> C:\Documents and Settings\All Users\Application Data\TEMP:430C6D84



•Then click the Run Fix button at the top
•Let the program run unhindered, reboot the PC when it is done
•Open OTL again and click the Quick Scan button.

I'm curious and concern about this value(below) in BootExecute which combofix isn't able to read, that could be a bad value and if a scanner removes it unsuccessfully it will cause the PC to not boot.
BootExecute      REG_MULTI_SZ         autocheck autochk *\0?????

You can also try these free online scanners:

For those programs that crashed, try running them by dragging them over the inherit.exe and see if they still crash. Try TDDSkiller first, if the crash are caused by some variant of ZA rootkit blocks, but then CF should've taken care of that if that was the case but worth a try.

Download inherit.exe by sUBs.
Drag the program's executable file into the inherit.exe and wait for it to say OK.

Thanks so much for all your help. After I ran the script in OTL, I ran TDSSKiller, and was then able to install and run McAffee. It found and removed some nasties. I think everything is working correctly now.

Again, Thanks.
