win32.Zafi.B removal

Hello Geek Police,

I know this is not a new topic but I could not see for the life of me how to actually post a question. I read the New Members stuff but is isn't clear how to actually post a question or perhaps I'm just stupid. Anyway, I'm being driven mad with the ghastly worm which stops me getting on line a lot of the time and I can't receive or send any emails.

I would be SO grateful if somebody could please tell me how to get rid of it. I'm a bit of a technophobe but can follow instructions. I'm using Windows XP and I've had this worm for about a week now I think. I've read a few of the other Win32.Zap posts but I'm confused about whether the answers only relate to the specific posts or not. Also I'm confused by the long lists of files people seem to be including in the posts. As you see I'm pretty clueless!

Please help! Many thanks!

Petronella

Dear Geek Police,

Can you give me any idea when somebody will be able to help me? ( I couldn't help noticing that someone else with a similar problem got a very quick reply from you last Tuesday.)

Is there anything I can do in the meantime to gather any information you might need in order to help me? If there is I'd be grateful if you could explain what I need to do in simple terms. Thank you!

Regards,
Petronella

Hello.
Please have some patience, I have college 7hrs on a Friday and don't get home till 4:30pm-ish, and then have some personal things to take care of before I have time to answer these threads.

Please download the current version of HijackThis from HERE

• Double click and run the installer.
  
• It will install to C:\Program Files\Trend Micro\HijackThis\hijackthis.exe
  
• After installing, you should get the user agreement, press accept and Hijack This will run.
  
• Select Do a system scan and save a log file. This will open a notepad file of everything Hijack This found, copy and paste it back here.
  

I'm really sorry to have hassled you - I didn't realise you were doing this in your spare time. It's a fantastic job you're doing - Sorry again! I'll now do what you're suggesting. Many thanks!

Petronella

Hi Belahzur,

I think I've done what you asked me to do right - let me know if I haven't. Thanks!

Petronella

Hello.
Not good.

Your computer has multiple infections, including a backdoor. A backdoor gives intruders complete control of your computer, logs your keystrokes, steal personal information, etc.

You are strongly advised to do the following:

• Disconnect the computer from the Internet and from any networked computers until it is cleaned.
  
• Back up all your important data except programs. The programs can be reinstalled back from the original disc or from the Net.
  
• Call all your banks, financial institutions, credit card companies and inform them that you may be a victim of identity theft and put a watch on your accounts. If you don't mind the hassle, change all your account numbers.
  
• From a clean computer, change all your passwords (ISP login password, your email address(es) passwords, financial accounts, PayPal, eBay, Amazon, online groups and forums and any other online activities you carry out which require a username and password).
  

Do NOT change your passwords from this computer as the attacker will be able to get all the new passwords and transaction records.

Due to its backdoor functionality, your computer is very likely to have been compromised and there is no way that it can be trusted again. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be to do a reformat and reinstallation of the operating system (OS). However, if you do not have the resources to reinstall your OS and would like me to attempt to clean your machine, I will be happy to do so.

To help you understand more, please take some time to read the following articles:

What are Remote Access Trojans and why are they dangerous
How do I respond to a possible identity theft and how do I prevent it
When should do a reformat and reinstallation of my OS
Where to backup your files
How to backup your files in Windows XP
Restoring your backups

Thanks so much for all this information. I'm just running off the information from the links you've provided so I can read and digest it.

I'm horrified that my computer is so badly infected when I've got anti virus and spyware which I check regularly. Thank you for offering to clean my computer which I think I'll want you to do but I need to read all the information first. It's very kind of you!

Did you mean back up all important data apart from programs i.e.programs on the Start menu?

I'm going to disconnect now and read all the stuff. Thank you again for your help; I am very grateful and I will be in touch soon when I'm more clued up about all the implications.

Regards
Petronella

Hello.
No, just back up anything like word documents that are important to you, all installed programs can be downloaded and installed again.

Hello,

I've read through everything now and will be backing up my documents shortly.

From the information you've looked at and given that I've got a built-in firewall with Windows XP, had installed AVG Anti-Virus (free version), SpyBot, Ad-Aware from the start (although Ad-Aware stopped updating some time ago which I couldn't get to the bottom of but I continued performing scans); I don't use games or visit chat rooms and am careful of opening email attachments, is there any clue or identity of the RAT and how I picked it up and how long I've had it so I can avoid this situation in future? (I was fooled into buying some bogus security software in October which I have since tried to remove.)

Thank you for offering to clean my machine but If I do need to Reformat and Reinstall the OS for greater future security, I do not feel at all confident in trying to do this myself, can you help or advise me how to go about getting it done and how much it might cost. Many thanks again for your help!

Petronella

Not sure how this got in, but I suspect it maybe from an email, even emails from legit emails of friends maybe infected, it's so easy to fake an email address.
It could even be just from visiting a bad website, you don't actually have to run any exe files or do anything nowdays to get infected.

Thanks for that. If I need to Reformat & Reinstall the os in order to have maximum future security, can you advise me how best to get this done. I've read the Reformat notes but would not feel confident to do it myself and don't know anyone else who I feel confident would do it properly.

Petronella

Sure.
To format, you'll need an XP disc.
Put it in and boot from it.

You'll reach a blue screen with text that tells you what to do.

You should be able to use the guides from there, because it could take along time if I type this out.

I'll obviously have to give it a try but I feel overwhelmed by the technology and am afraid that if I don't do it properly, I'll be back to square one. Is there anyone you could recommend who could do it for me?

Petronella

From us? not really.
You could take it to a local tech guy, or someone who knows this stuff around where you live.
I dunno if someone like PCWorld will format it for you if you pay, but you can ask.

Since this issue has been addressed, a "solved" tag will be added and this topic will be closed.
