Hello. This is my first post here so i hope i am in the right place.

I am running xp and need to reinstall due to my pc being infected with a win3.ramnit virus. Problem i have though, is that i don't have any disks. Is there any way to reinstall with out them? I didn't get any disks with the pc and think i was meant to make a recovery disk but didn't realise this untill now. If I make the recovery disk now will i just end up putting the virus back on?

thanks for your help

System manufacturer and model?

Have you contacted the manufacturer and inquired about getting replacement recovery/restore disks?

<<Have tried to remove the virus but read on here that the ony way to get rid of win32.ramnit is to reinstall>>

Curious...I thought that I saw a comment pertaining to such also...I find it interesting that others think that our Malware Team can handle it.

http://social.answers.microsoft.com/Forums...e6-0729781719b6, see comment by Mod there.

If I were you...I'd try to get the replacement recovery disks (since you need those regardless of how this venture comes out) and I would also initiate a malware thread here at BC.

You should be aware that a malware post here will involve a delay of several days...but your thread will be answered and reviewed by competent personnel.

Should you choose to go that route, follow the instructions from Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html.

Then...post the log and some narrative summary at BC Virus, Trojan, Spyware, and Malware Removal Logs - http://www.bleepingcomputer.com/forums/forum22.html. Do not post the log data requested in the XP forum.

I found what I believe you have seen posted previously.

Bear in mind...that the name for a given malware item...must be considered fully...when attempting to research, etc. I will post the content of what I have seen.

"I'm afraid I have very bad news.

Win32/Ramnit.A is a file infector with IRCBot functionality which infects .exe, and .HTML/HTM files, and opens a back door that compromises your computer. Using this backdoor, a remote attacker can access and instruct the infected computer to download and execute more malicious files. The infected .HTML or .HTM files may be detected as Virus:VBS/Ramnit.A. Win32/Ramnit.A!dll is a related file infector often seen with this infection. It too has IRCBot functionality which infects .exe, .dll and .HTML/HTM files and opens a back door that compromises your computer. This component is injected into the default web browser by Worm:Win32/Ramnit.A which is dropped by a Ramnit infected executable file.

-- Note: As with most malware infections, the threat name may be different depending on the anti-virus or anti-malware program which detected it. Each security vendor uses their own naming conventions to identify various types of malware.With this particular infection the safest solution and only sure way to remove it effectively is to reformat and reinstall the OS.

Why? The malware injects code in legitimate files similar to the Virut virus and in many cases the infected files (which could number in the thousands) cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files often become corrupted and the system may become unstable or irreparable. The longer Ramnit.A remains on a computer, the more files it infects and corrupts so the degree of damage can vary.

Ramnit is commonly spread via a flash drive (usb, pen, thumb, jump) infection where it copies Worm:Win32/Ramnit.A with a random file name. The infection is often contracted by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malware and a major source of system infection.

In my opinion, Ramnit.A is not effectively disinfectable, so your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. Further, your machine has likely been compromised by the backdoor Trojan and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if your anti-virus reports that the malware appears to have been removed.

Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include:
• Reimaging the system
• Restoring the entire system using a full system backup from before the backdoor infection
• Reformatting and reinstalling the system

Backdoors and What They Mean to You

This is what Jesper M. Johansson at Microsoft TechNet has to say: Help: I Got Hacked. Now What Do I Do?.

The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).


Important Note:: If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to 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. You should change each password using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Failure to notify your financial institution and local law enforcement can result in refusal to reimburse funds lost due to fraud or similar criminal activity."

Louis

Soooo...my question is who determined what is ailing your system...and how?

I have read the guide you linked to and have tried to run the logs but keep getting a error message saying it is not a valid win32 application. I have not posted a messag in the virus forum as i can not get the logs.

Can I ask something though, my brother has a copy of windows xp that is installed on a pc he doesn't use. If he wiped it off that pc could i put it on mine. That way i could reformat and reinstall windows. Would this work and is it legal?

Thanks

Your system is an E Systems ei 314, which appears to be an MCE system,
http://www.xpertonline.co.uk/proddetail.as...864&cat=254.

These systems normally came with MCE installed and that should be the applicable O/S your license relates to.

Not all versions of Windows are the same...a license for one version does not apply to a different version...a license that is tied to a system does not relate to moving that install to a different sysem, whether it is used on a second system or not.

Based on the info you have submitted thus far...I don't believe your questions posed in your last post...can be answered specifically. The answers depend on the licenses for each system and the nature of the CD to be used for the proposed reinstall.

Ok so that probably wont work then. Think I might go back to your original idea and get on to the manufacturer.

Thanks for your time and help
