Hi all,

I've noticed something that looks for me like a infection:

First, my ms outlook did not start at startup (it is in startup in start menu). I ran it manually but it stopped during a send/receive process.
Then I've noticed that there is no eset nod32 antivirus icon in tray.

So i went to safeboot, and manually turn on nod32 system scan. After 5 hours of scanning i've rebooted the computer, but nothing changed. When i tried do search for sollution it appeared that i can't open websites (e.g. google ) - they are starting to load but don't appear. On other computer I've checked the processes runned on my machine and one that could be suspicious - igfxpers.exe (according to bleepingcomputer knowledge base) I turned off from msconfig / run. After a reboot Outlook started like it should, but nod32 - not.

I wanted to manually inspect my registry but regedit and cmd don't launch.

Possible source of infection:
Yesterday, I've tried to enter one comapny's website. google chrome gave me a warning that this site could be dangerous. Before calling to that company with warning, I've wanted to ensure that the warning is real, and I tried to enter that site from google search in Firefox - there was no warning this time. I know some of that kind of threats so i checked the source of website but there was no suspicious (as for me ;)) code - lately I've been founding some weird scripts at the end of source, sometimes hidden in ASCII (%23 %54 and so on).

Please help - It's my work computer!

Thanks!

OS: Win XP Pro SP3

Update: I'm able to manually run nod32 in normal mode

Hello can you get MBAM to run


Please download Malwarebytes Anti-Malware (v1.36) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Hello,

Thanks for answer :thumbsup:

Unfortunately, MBAM found no malware. I took a risk ( i did it several times before) and ran ComboFix. I know I shouldn't but i need to work! It seems it helped - outlook and nod32 launch at startup, I can run the regedit and cmd.
Should I post a ComboFix log ?

Here comes log from MBAM.

That's good news!!
Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
