Hello. I'm using Windows XP Service Pack 2. I recently installed Spybot S&D, and it discovered zlob.downloader.bit but failed to remove it. It asked to be allowed to run at start up. I said yes and rebooted. It found zlob.downloader.bit again and again failed to remove it. I googled the problem and found a post on this forum with a similar problem. That person was advised to do the following, and I did this also.

Try a scan with this and let us know..
Download and scan with SUPERAntiSpyware Free for Home Users

Double-click SUPERAntiSpyware.exe and use the default settings for installation.
An icon will be created on your desktop. Double-click that icon to launch the program.
If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download and unzip them from here.)
Under "Configuration and Preferences", click the Preferences button.
Click the Scanning Control tab.
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining.

Click the "Close" button to leave the control center screen.
Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
On the left, make sure you check C:\Fixed Drive.
On the right, under "Complete Scan", choose Perform Complete Scan.
Click "Next" to start the scan. Please be patient while it scans your computer.
After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
Make sure everything has a checkmark next to it and click "Next".
A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
If asked if you want to reboot, click "Yes".


But when I ran Spybot again after rebooting, it found the problem yet again. What should I try next? Thank you.

Since Spybot identified the problem as being HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Pornovid, I used regedit and deleted that folder. Just in case the solution really was that simple.

I'm now running both Spybot and SUPERAntiSpyware again to see if they still find it. Will report back with the results...

...

Both programs came back with no problems found. Rebooted the computer and ran Spybot again, and it still didn't find anything wrong. So, am I clean now? Why was I able to so simply delete HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Pornovid when Spybot failed to remove it? Do I need to do anything else to make sure it doesn't come back?

FYI: mvps.org is no longer recommending Spybot S&D or Ad-Aware due to poor testing results. See here - (scroll down and read under Freeware Antispyware Products). Further, most people don't understand how to use Spybot's TeaTimer and that feature can cause more problems than it's worth. TeaTimer monitors changes to certain critical keys in Windows registry but does not indicate if the change is normal or a modification made by a malware infection. The user must have an understanding of the registry and how TeaTimer works in order to make informed decisions to allow or deny the detected changes. If you don't have understanding how a particular security tool works, then you probably should not be using it. Additionally, TeaTimer may conflict with other security tools which do a much better job of protecting your computer and in some cases it will even prevent disinfection of malware by those tools.

More effective alternatives are Malwarebytes Anti-Malware and SUPERAntiSpyware Free.


Please download Malwarebytes' Anti-Malware (v1.50.1) and save it to your desktop.
  • Double-click on the setup file to install, then follow these instructions for doing a Quick Scan in normal mode.
  • Don't forget to check for database definition updates through the program's interface (preferable method) before scanning.
Malwarebytes' 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.
  • After completing the scan, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab .
  • 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 the database version and your operating system.
  • Exit Malwarebytes' when done.
Note: If Malwarebytes' encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes' from removing all the malware.

-- Some types of malware will target Malwarebytes Anti-Malware and other security tools to keep them from running properly. If that's the case, please refer to the suggestions provided in For those having trouble running Malwarebytes Anti-Malware as you may need to rename it or use RKill by Grinler.

Try doing an online scan to see if it finds anything else that the other scans may have missed.

Please perform a scan with Eset Online Anti-virus Scanner.
  • If using Mozilla Firefox, you will be prompted to download and use the ESET Smart Installer. Just double-click on esetsmartinstaller_enu.exe to install.
  • Vista/Windows 7 users need to run Internet Explorer/Firefox as Administrator. To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.[/color][/i]
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser and allow the download/installation of any require files.
  • Under scan settings, check Posted Image and check Remove found threats
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • Click the Start button.
  • ESET will install itself, download virus signature database updates, and begin scanning your computer.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
    If given the option (when threats are found), choose "Quarantine" instead of delete.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply. If no threats are found, there is no option to create a log.

Your scan results indicate a threat(s) was found in the Java cache.

When a browser runs an applet, the Java Runtime Environment (JRE) stores the downloaded files into its cache folder for quick execution later and better performance. Both legitimate and malicious applets, malicious Java class files are stored in the Java cache directory and your anti-virus may detect them as threats. The detection can indicate the presence of malicious code which could attempt to exploit a vulnerability in the JRE. For more specific information about Java exploits, please refer to Virus found in the Java cache directory.

Notification of these files as a threat does not always mean that a machine has been infected; it indicates that a program included the viral class file but this does not mean that it used the malicious functionality. As a precaution, I recommend clearing the entire cache manually to ensure everything is cleaned out:
Also be aware that older versions of Java have vulnerabilities that malicious sites can use to exploit and infect your system. That's why it is important to always use the most current Java Version and remove outdated Java components.Even Java advises users to always have the latest version of the Java since it contains security updates and improvements to previous versions.

The latest Java version contains important enhancements to improve performance, stability and security of the Java applications that run on your machine. Installing this free update will ensure that your Java applications continue to run safely and efficiently.

Why should I upgrade to the latest Java version?
Why should I upgrade to Java 6?

You can verify (test) your JAVA Software Installation & Version here.

How is your computer running now? Are there any more signs of infection?...strange audio ads, unwanted pop-ups, security alerts, or browser redirects?

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 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 Posted Image > 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 Posted Image > 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.

You're welcome.

:thumbup2: Tips to protect yourself against malware and reduce the potential for re-infection:

Keep Windows and Internet Explorer current with all security updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. When necessary, Microsoft releases security updates on the second Tuesday of each month and publishes Security update bulletins to announce and describe the update. If you're not sure how to install updates, please refer to Updating your computer. Microsoft also recommends Internet 6 and 7 users to upgrade their browsers due to security vulnerabilities which can be exploited by hackers.

Avoid gaming sites, porn sites, pirated software (warez), cracking tools, and keygens. 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. In some instances an infection may cause so much damage to your system that recovery is not possible and the only option is to wipe your drive, reformat and reinstall the OS.

Avoid peer-to-peer (P2P) file sharing programs (i.e. Limewire, eMule, Kontiki, BitTorrent, BitComet, uTorrent, BitLord, BearShare). They too are a security risk which can make your computer susceptible to malware infections. File sharing networks are thoroughly infected and infested with malware according to Senior Virus Analyst, Norman ASA. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious 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.
Beware of Rogue Security software as they are one of the most common sources of malware infection. They infect machines by using social engineering and scams to trick a user into spending money to buy a an application which claims to remove malware. For more specific information on how these types of rogue programs install themselves and spread infections, read How Malware Spreads - How did I get infected.

Keeping Autorun enabled on flash drives has become a significant security risk as they are one of the most common infection vectors for malware which can transfer the infection to your computer. One in every eight malware attacks occurs via a USB device. Many security experts recommend you disable Autorun as a method of prevention. Microsoft recommends doing the same.Note: If using Windows 7, be aware that in order to help prevent malware from spreading, the Windows 7 engineering team made important changes and improvements to AutoPlay so that it will no longer support the AutoRun functionality for non-optical removable media.

Always update vulnerable software like browsers, Adobe Reader and Java Runtime Environment (JRE) with the latest security patches. Older versions of these programs have vulnerabilities that malicious sites can use to exploit and infect your system.
Change all passwords: Anytime you encounter a malware infection on your computer, especially if that computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and any online activities which require a username and password. You should consider them to be compromised and change passwords as a precaution in case an attacker was able to steal your information when the computer was infected. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connecting again.

• Finally, use common sense, safe computing and safe surfing habits provides the most complete protection.
