Hi, I have a really strange problem.
When I opened my pc yesterday, on the desktop appeared a Security Center Alert warning me about a lot of different virus (trojan and so on). Then appeared a tray icon like the one of the Windows security center and when I checked it the Virus protection said: Not found. But my antivirus (Comodo) was already running. I scanned my pc with comodo and the result was that it was perfectly clean. I thought that comodo wasn't working correctly (my brother already had problems with it) and tried to scan my pc with AVG (uninstalling comodo asap and not leaving my pc without protection). Well, AVG failed the installation everytime, so I couldn't scan anything.
In the meantime, an antimalware program is constantly trying to install itself automatically. I tried to block it but all I can do is shut down everytine the process by the task manager. Moreover, the real windows security center ceased to work.
I'm without an antivirus, firewall and so on.

I really don't know what to do.
Every 5 min the (fake?) security alert warn me with another virus infection.

Can you help me, please?

I don't know if the security alerts are real. In any case, I'll post here some of the virus that iwas warned about:

viruschin9.win
trojan.win.agent.dcc
backdoor.win32.agent.ich
backdoore.win32.kbot.al

Hello and welcome please run these next. If you have Spybot installed temporarily disable it.
Next run ATF:
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

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. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Looks good. If there are no more signs of malware then....
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 and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
