I'm having a problem in my PC. I tried to log on to the Avira site to download updates but my browser returns back with a "Failed to connect to server". Then I checked other AV sites like symantec, mcafee, f-secure, kaspersky, etc. but it seems I can't connect to them either. I've tried both my Internet Explorer and Firefox but both of them can't connect to those sites. Even trying to connect to anti-malware sites like Spybot, Spywareblaster and MalwareBytes. I can't do some online scanning too like F-Secure Online Scanner, TrendMicro Housecall, ESET Online Scanner, etc. - all blocked off.

But if I log-in a site that's not anti-virus or anti-malware related, the site works (fortunately, this site bleepingcomputer.com works) so I suspect that a trojan (which I found out recently that there was an infection from a USB which was un-scanned without my attention) modified my sites and blocked those AV/AM sites.

When I tried to use System Restore to revert back to my good system, all of my previous good states are wiped off. And prior to that, my Show hidden files and folders we're turned-off too (modified my registry again). I've scanned my system with MalwareBytes (not updated since yesterday) and solved that problem but I still can't connect to those AV/AM sites like I said before. Now I can't even update MalwareBytes because something blocks it off. I can't even download the SuperAntiMalware program while I'm checking at other posts for some relevant symptoms.

I'm using Windows XP Home and there's my problem. I need help. Thanks in advance.

Let's get a Malwarebytes log with what you have.

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 you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes.

Here's my latest MBAM log after the scan:

But the problem still persisted after that. Well just as I'm about to give up and calling it a day, I rebooted my PC. When it restarted, my Avira anti-virus detected this prior to start-up:

I moved it to my quarantine for the moment (if anyone wants it for analysis). With that out of the way, my PC still blocks the AV sites. Then I restarted and it's back to normal again. I can now visit the AV sites without problems. I'll perform an MBAM full scan tomorrow morning to see if there some more hidden problems left in my system.

Your definitions are very old. Can you download Malwarebytes and its definitions on another computer and move it to this computer via pen/flash drive?

We can also try SDFix...
Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

You should be using Malwarebytes' Anti-Malware v1.32 and the database should be at least 1631.

Finished!


My PC's good now and I've found the culprit as well. It seems that my friend plugged-in his USB flash drive without knowing that there's the WORM/Kido.EO worm within in when I scanned the drive with Avira. I trusted him that he won't have any viruses or trojans on his USB drive because I'm the one who configured his own PC system as a clean install. Now I don't trust him for the moment but he said he was sorry.

Anyways, thanks for the help guys! :thumbsup:

You are most welcome :thumbsup:

Just to be sure I would run another scan with the updated Malwarebytes.

If there are no more problems or signs of infection, 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 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.
  • 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.
Safe surfing

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, underground web pages, pirated software, crack sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. Read USB-Based Malware Attacks and miekiemoes' Blog: Please disable Autorun asap!.

You can hold down the Shift key when inserting the drive into your computer until Windows detects it to keep autorun.inf from executing automatically. However, I recommend disabling the Autorun feature on USB and removable drives as a method of prevention. This should keep the malicious file from automatically running upon insertion and infecting your system while allowing you to safely perform a scan.

The easiest way to disable Autorun on a specific drive is to download and use Tweak UI PowerToy.
  • After installation, launch Tweak UI, double-click on My Computer in the tree menu on the left, then click on AutoPlay > Drives. This will allow you to change the system settings for AutoPlay/autorun.
  • Uncheck the drives you want to disable AutoPlay on and click on Apply.
  • Next, click on the Types in the left tree. This allows you to control whether Autoplay is enabled for CD and DVD drives and removable drives. You may need to restart Tweak UI if it closes after step 2.
  • Uncheck the box to disable Autoplay for a particular type of drive.
  • Click Apply.
If needed, see Disable Autorun/AutoPlay in XP with Tweak UI" for instructions with screenshots.

Note 1: When Autorun is disabled, double-clicking a drive which has autorun.inf in its root directory may still activate Autorun so be careful.

Note 2: Disabling autorun/autoplay does not prevent you from accessing your media sources. They are still available by opening My Computer and accessing the source drive (CD, DVD, usb/flash drive or external hard drive). Pictures on a camera can still be accessed through My Pictures and selecting "Get Pictures" from a scanner or camera. Media can also be accessed via the program you normally use it with such as music CDs accessed via Media Player, blank CDs via burning software, image handling software provided with the camera, etc. I strongly recommend you leave the autorun feature disabled and get into the habit of accessing your media devices manually.


Always scan USB Flash Drives after they have been used in other computer systems, even your own. An easy way to do this is to download "ClamWin Portable Antivirus", put it on your USB Flash Drive, update its definition files and perform a scan.

Another prevention measure you can use is Flash_Disinfector.exe, a specialized fix tool created by sUBs to remove infections that load an autorun.inf file on removable media. After running the tool, it will also create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in to stop malware from spreading. This folder will help protect all drives from future infection.
