Win32/Zbot.g and VBS/Generic

6 posts in this topic

I am at my wits end with this virus and I could really do with some help. Just over 24 hours ago my AVG Resident Shield Alert detected multiple cases of Win32/Zbot.g and VBS/Generic. I clicked on Remove selected as advised by AVG but the same viruses just keep on coming. As soon as I switch my computer on I have hundreds of cases of Win32/Zbot.g and VBS/Generic appear and be detected in AVG Resident Shield and I can't keep removing them as it is endless. I have run Mbam and no infections were found but AVG Resident shield keeps on detecting them. I cannot open AVG to run the virus software as I get an error message and I cannot connect to the internet as this doesnt work either. I'm having to use a laptop and copy files from one to the other. Is it ok to copy to cd and then copy that to the infected PC as I do not have a USB stick. I'm not really sure what to do next and could really use some advice.

Hi and welcome to Malwarebytes.

A Zbot detection is a backdoor trojan. A backdoor severely compromises system integrity.

A compromised system may allow illicit network connections, disabling of security software, modifying critical system files and collection and transmiission of personal identifiable information without your consent.

I recommend that you disconnect this PC from the Internet immediately, and only reconnect to download any tools that are required. If you do any banking or other financial transactions on the PC or it if it contains any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the Trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be a reformat and reinstall of the OS. If it were on my PC I would not hesitate for a moment to do so. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

When Should I Format, How Should I Reinstall

Should you decide not to follow that advice, we will of course do our best to clean the computer of any infections that we can see but, as I already stated, we can in no way guarantee it to be trustworthy.

Should you have any questions, please feel free to ask.

Let me know what you decide.

Hi, thank you for getting back to me. I think you have just confirmed what I had suspected, that a reformat would be the only safe thing to do. I managed to copy a trial version of Spyware Doctor onto the infected PC and it detected multiple cases of ramnit which I understand is a severe virus. I have a Compaq Presario PC and if my understanding is correct, if I use the HP Destructive Recovery that comes pre installed on the PC then it will format the hard drive and re-install Windows XP that came pre-installed on my PC and put everything back to factory setings. No recovery discs/cd's were provided. Can you confirm that this is the correct action to take for a reformat and reinstall.

Thanks,

Stuart.

Sorry, one last thing that I forgot to ask in my last message, the only thing on the PC that I need to salvage is several hundreds of digital camera photos that are stored under adobe and Kodak easyshare. My worry is, if I copy these onto a cd ready to be transfered back after reformat and reinstallation, is there any chance that these could be carrying any malware/viruses as I dont want to reinfect the clean PC.

Hi,

Yes, the destructive restore partition is the way to go.

I don't believe you have a file infector, so your image files should be safe to back up.
