Hi there,
I have my "own" akamaihd infection on two PCs in my network. So, I attach the logs, except for aswMBR.ex due it crashes after a few minuts scanning (anyway, I attach the screen image).
Please, help me first with this one because in spite you said "it's not a virus", after the infection I can't start normally such PC due some errors (attached too)
-
More attached files...
-
And one more...
-
Hi,
Please download AdwCleaner (http://www.bleepingcomputer.com/download/adwcleaner/) by Xplode and save to your Desktop.
Double click on AdwCleaner.exe to run the tool.
- Click on the Scan button.
- After the scan has finished click on the Clean button.
Press OK when asked to close all programs and follow the onscreen prompts.
Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
- After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
- Post logfile will also be saved in the C:\AdwCleaner folder.
Please download Farbar Recovery Scan Tool (http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/) by Farbar and save it to your desktop.
Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.
- Double-click to run it. When the tool opens click Yes to disclaimer.
- Under Optional Scan ensure "List BCD" and "Driver MD5" are ticked.
- Press Scan button.
- It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
- The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
Please download GMER, AntiRootkit tool from the link below and save it to your Desktop:
Gmer download link (http://www2.gmer.net/download.php)
Note: file will be random named
Double-clicking to run GMER.
- Wait for initial scan to finish - if there is any query, click No;
- Click Scan button and wait until the full scan is complete;
- Click Save ... - save the report to the Desktop (named Gmer );
> Attach here Gmer logreports.
-
The AdwCleaner seems to be problematic due when the PC restarts doesn't start but in safe mode with network. Anyway, it offers the logs (attached).
-
The attachments (sorry)
-
The farbar and gmer logs. And the errors from W7 system when starting in normal mode...
-
Frst report isn't complete. You're missing Addition.txt too...
-
Hi TwinHeadedEagle.
As I told you, the programs are not running properly (perhaps due we can't start W7 normally, but just in "safe mode with network"). I attach the execution results for FRST64.exe and the aswMBR.exe as well. I've tested even only marking the addition.txt checkbox, without success.
Next step, please?
Thank you in advance.
-
Just in case, I guess I could start the avast! remote assistant for you...
-
Can you boot to Safe Mode, and run FRST from there?
-
Sorry for the delay. Each time we restart... is a (new) mess.
Attached you will find the fstr files.
Thank you in advance.

-
Here you have!
-
The previous one was the log opened automatically. Here you have the ComboFix.txt
Thank you!
-
How are the things now?
-
Still the same, TwinHeadedEagle.
If I try to start normally the PC, once I enter my user password, the system freezes in "starting" forever.
If I start in safe mode (with or without network access), the browsers open akamaihd pages freely or show multiple pop-ups or ads. Obviously, the rest of the behaviour is very poor due such "safe mode".
Perhaps I miss something after sending the ComboFix.txt files... Am I wrong? Any hints to step forward?
Thank you in advance.
-
Can you boot to Normal mode, and post fresh FRST report...
-
Perhaps my english is not so good to explain as fine as I would like. I'm sorry.
I can't start in normal mode. Just after entering the user password (is the same admin or guest) the system stops at "initializing" screen and doesn't go ahead anymore.
Maybe I'm misunderstanding your idea about "normal mode" but there is no way.
-
OK, we will need to scan system outside Windows...
Please download Farbar Recovery Scan Tool x64 (http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/) and save it to a flash drive.
- Plug the flashdrive into the infected PC.
- Restart your computer and tap F8 to bring up the Advanced Menu, then click Repair your computer
- Follow the prompt to enter keyboard input method, and then the prompt to enter a password. If the machine does not have a password, simply click Enter.
In the next menu, use the arrow keys on the keyboard to highlight Command Prompt and press Enter.
- In the command window type in notepad and press Enter.
- When notepad opens, click File and select Open.
- Select "Computer" and find your flash drive letter and close the notepad.
- In the command window type e:\frst64.exe and press Enter.
Note: Replace letter e with the drive letter of your flash drive.
- The tool will start to run. When the tool opens click Yes to disclaimer.
- Press Scan button.
It will make a log (FRST.txt) on the flash drive. Please attach it to your reply.
-
Here you have.
Remember my PC is now waiting in "repair your computer" mode.
Thank you.
-
There is no malware on your PC, but there is a possibility that Avast and Panda Internet Security interfere with one another...so we're going to remove Panda and see what is happening...
Open notepad.
- Click Start
- Type notepad.exe in the search programs and files box and click Enter.
- A blank Notepad page should open.
- Copy/Paste the contents of the code box below into Notepad.
S3 PSKMAD; C:\Windows\System32\DRIVERS\PSKMAD.sys [47632 2013-04-28] (Panda Security, S.L.)

- Save it to your USB flashdrive as fixlist.txt
>> Boot into Recovery Environment
Start FRST in a similar manner to when you ran a scan earlier, but this time when it opens ....
- Press the Fix button once and wait.
- FRST will process fixlist.txt
- When finished, it will produce a log fixlog.txt on your USB flashdrive.
>> Exit out of Recovery Environment and post me the log please.
Try to boot Windows normally...
-
Once again, here you have the result
-
Four your info: after trying to restart in "Normal mode", the pc is freeze again just after entering the user password.
-
When did this issue happen, what time exactly, before Avast warning about this PUP, or after...
-
Actually, I'm not sure Avast starts properly.
The W7 starts in normal mode. Then offers the login for my two users (both with administrative capabilities). Then I click on one of them and the system request the password. Just after entering the password and pressing enter, the system shows the "initializing" screen. A few seconds later, the screen goes to black. I can move the mouse and the keyboard answers to "caps", "numlock" and more.
If I try with ctrl-alt-supr, escape or whatever you could consider to interact with the system... simply does nothing: the black screen keeps on.
I would like to remember I have the avast! Endpoint Protection Suite, managed by the server machine as a SOA. And, perhaps is useful for you, the server detects my PC as terminal. But once logged in (and in black screen), the servers "deactivates" my PC as terminal. So, my conclussion is obvious: once identified in "normal mode" something wrong happens.
-
I am not familiar with servers and Endpoint protection, pc is malware clean, you can try to remove avast and see what is happening...
-
Following your hints, I've uninstalled the avast! Endpoint. After that, the system started in normal mode properly (so, the error was in avast?).
Then I've reinstalled the Endpoint (and ran a complete scan) with success.
After that, I've repeated the FSTR64 execution (I attach the results).
Please, could you have a look on them in order to confirm if in your opinion everything is solved at all?
The browsers seems to be ok, not showing pop-ups, nor unwanted ads, neither redirecting to akamaihd webpages. But any inspection from you will be welcome.
Thank you very much!
PS.- If solved, I will start sending the logs for the second PC infected, if you don't mind...
-
This PC is clean. I want you to do the following:
- Uninstall Java from Control Panel, and install the latest version --> http://java.com/en/

files, execution time should be anywhere from a few seconds to a minute
or two. Let it run uninterrupted to completion.
- Once it's finished it should reboot your machine. If it does not, please manually reboot the machine yourself to ensure a complete clean.
