Hi guys,

Thx in advance for the help. My brothers computer picked up some malware that starting causing all sorts of pop ups. He then rebooted, into safemode w/ networking support and ran mcafee. The scan basically found all .exe files on the computer to be infected and since it could not clean them deleted them. The scan has ended but the window is still open. This is the time he decides to call me who knows only a little more than him.

I said don't reboot just yet until we can figure things out.

Where we stand. The computer will not recoginze any jump drives, sees the cd drive as "not accessable - incorrect function" and no programs work. I cannot see any network to get internet access or even connect through lan to another computer.

I am guessing since mcafee lists all .exe as deleted this is the cause. My question is can i restore these .exe's since mcafee has not yet closed out (recycle bin is empty)? or is there another way to save these files. System restore did not seem to be disabled but dont trust that it will work.

thx

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.

Oh dear. That sounds like a mess. I'll want someone more knowledgeable than I to confirm, but it sounds as though the .exe files were corrupted or infected by a really bad infection and it's quite possible that a reformat and reinstall is the only solution even if the files can be recovered.

The scan basically found all .exe files on the computer to be infected and since it could not clean them deleted them.


Ouch. Are you certain they were deleted and not quarantined? It is always wiser to quarantine files - that way if something is a false positive, it can be restored from the quarantine. If they were actually deleted, I'm afraid they are history. Question: was the McAfee scan an on-line scan or with an fully installed product? If the latter, it MIGHT have created a back-up folder, but I wouldn't count on that. I haven't used McAfee, so I couldn't tell you.

System restore did not seem to be disabled but dont trust that it will work.


System restore will not work if the files are not present.

Hey there. the files were listed as deleted but since the scan was not closed out I was hoping that the full deletion did not occur until closure. BTW it was an installed program that was run. At this point the only thing i am looking for is to rescue the word files i need.

Any suggestions to get the cd drive or jump drive working in order to accomplsh this?


thx

Your infections sounds similar to virut. Did McAfee give you a name of the infector? If you deleted vrs quarantined the files, I don't think you can get them back. You can try rolling back to a system restore point from an earlier date of your scan.

The name that comes up on most of them are new win 32 , or new poly win32. Also on a rare occasion vundo.

I am able to read cd's and copy files from cd's onto the harddrive. Is there someway that i can reinstall something like the jumpdrive capability using this ability or with the files still in the windows folder?

Thx

See if you can find a McAfee log and post it here. That way we can see what we are dealing with. If your infection is indeed virut, you will want to reformat without saving.

I wont be able to post the log unfortunately. Thats the major part of my problem. I can't open majority of programs due to missing exe files and i cant get online access either. I can see the logs and open them. There were 1722 files deleted all exe's. The scan was run in safe mode with networking capapbility, so it is also still in that mode, as I have not touched anything since it finished for a fear of finalizing the deletion

If i could get a jump drive working or be able to burn something onto a cd or even get network activity to dump files on another computer I would be ecstatic.

what do you suggest?

thx

I spoke with one of our resident malware experts. He agrees with my assessment. Ocne a file has been erased with McAfee, it is gone for good. The infection sounded like Virut, so you do not want to try and recover your files. You may wish to ask McAfee if there is anything else you can do, but I do not see a solution.

Virut is a polymorphic file infector with IRCBot functionality which infects .exe, .scr files, downloads more malicious files to your , and opens a back door that compromises your computer. Virux is an even more complex file infector which can embed an iframe into the body of web-related files and infect script files (.php, .asp, and .html). When Virut creates infected files, it also creates non-functional files that are corrupted beyond repair. In many cases the infected files cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files become corrupted and the system may become irreparable.

The virus has a number of bugs in its code, and as a result it may misinfect a proportion of executable files....some W32/Virut.h infections are corrupted beyond repair.

McAfee Risk Assessment and Overview of W32/Virut

There are bugs in the viral code. When the virus produces infected files, it also creates non-functional files that also contain the virus...Due to the damaged caused to files by virut it's possible to find repaired but corrupted files. They became corrupted by the incorrect writing of the viral code during the process of infection. undetected, corrupted files (possibly still containing part of the viral code) can also be found. this is caused by incorrectly written and non-function viral code present in these files.

AVG Overview of W32/VirutThis kind of infection is contracted and spread by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malware and an increasing source of system infection. However, the CA Security Advisor Research Blog says they have found MySpace user pages carrying the malicious Virut URL. Either way you can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS.

...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...

Keygen and Crack Sites Distribute VIRUX and FakeAV

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 include those used for banking, email, eBay, paypal and online forums. 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. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:There is no guarantee this infection can be completely removed. In some instances it may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. 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. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Please read:

Thats not good news. Is there anyway that i can install or reinstall a program at this point through a cd that will reenable by cd burning or jumpdrive capabilities. I am able to read cd's and copy files onto the drive from the cd's

The files i want to save are only microsoft xcel and word files.

Is there a microsoft program that will allow me to reinstall its recognition of my jumpdrive w/out having to restart my computer?

thx, really appreciate your help

With Virut infections, any type of repair probably will not work. That's why we recommend starting over by reformatting, and performing a clean install of the OS.

If your CD drive is not working, then another option is to remove the infected hard drive and install a new. You can configure the old hard drive as a "slave". That way you should be able to access it and salvage some of your data files. For instructions on how to do this, see:Also keep in mind, with a Virut infection, there is a chance you will infect the new hard drive. If the data is that important to you, then you can try to salvage some of it but there is no guarantee so be forwarded that you may have to start over again afterwards if reinfected by attempting to recover your data in this manner. You can then try to salvage your important documents, personal data files, photos. Do not attempt reovery of any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, and .html) files because they may be infected by malware. Avoid recovering compressed files (.zip, .cab, .rar) that have executable files inside them as some types of malware can penetrate and infect .exe files within compressed files.

Thx for the advice. Unfortunately this computer is a laptop so taking any old hd from my desktop is an option i would rather try and avoid. I am really just looking to find out what files i need to get back on my computer to get the jumpdrive working again or the cd drive working fully. That will enable me to get some very impt word and excel documents only.

I know this may just transfer infected files but i HAVE to try this. Anyone know what files must be present and in what folders to get the jumpdrive to be recognized?

Thx in advance

There is no way for anyone to identify every file that was affected.

If you insist on trying to fix this infection instead of following our advice to reformat and reinstall your operating system, there are various rescue disks available from major anti-virus vendors which you can try. Keep in mind, even the vendors like Kaspersky say there is no quarantee that some files will not get corrupted during the disinfection process. In the end most folks end up reformatting out of frustration after spending hours attempting to repair and remove infected files. IMO the safest and easiest thing to do is just reformat and reinstall Windows.

Bleeping Computer DOES NOT assume any responsibility for your attempt to repair this infection using any of the following tools. You do this at your own risk and against our advice.

These are links to Anti-virus vendors that offer free LiveCD or Rescue CD files that are used to boot from for repair of unbootable and damaged systems, rescue data, scan the system for virus infections. Burn it as an image to a disk to get a bootable CD. All (except Avira) are in the ISO Image file format. Avira uses an EXE that has built-in CD burning capability.If you are not sure how to burn an image, please read How to write a CD/DVD image or ISO. If you need a FREE utility to burn the ISO image, download and use ImgBurn.
