Hi, i was recently infected by few trojans and worms I believe. I don't remember most of their names but i managed to delete some of them manually but a few of those return after logging off or restarting the computer. some virus i might have on the system are

reader_s.exe
bkp.exe

someone has also hacked my passwords using seabra password stealer and the worse part is whoever sent the virus, it has killed all my anti-virus including combofix. it corrupted my "unhackme" program first so that it won't start and when i started the latest version of combofix, it started but after a while it gave an error with no message and crashed and deleted itself from my hard-drive..please i need your help desperately :thumbsup:

Hi Warpath,

The reader_s.exe file, plus a few other things I see in your second post, indicate that your system is infected with Virut.

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:

regards, Elise

i know that, but is there some way to try to get rid off it ? dr.web failed because it infected it too. i took a long time (12 hours) to scan my drives but after scan, the "cure" button didn't work so i renamed them but because most of the files renamed were system files, i didn't know what to do so I system restored to when i downloaded dr .web and though the virus seems to be missing for now (can't find the reader files ) though the.tmp files do keep forming in system32. i hope u can help me get rod of it completely without deleting all my programmes via reformatting and reinstalling windows which are worth a lot of money :thumbsup:

Hello Warpath, the infection on your system cannot be removed.
Please read my first post to see more information. Even if we would be able to clean out your computer, a part of your files, including those needed for a good and stable performance, are corrupted and remain so after cleaning up. This infection also created a backdoor which makes your computer unsafe. Any password or banking information can be stolen.
The only option you have is to reformat and reinstall Windows. You can back up non-infected files (see my first post) and restore them after your reinstall.

I am sorry not to be able to help you.

regards, Elise

Hello Warpath,

First of all, I recommend you to search some information about file infectors and Virut if the above information leaves you with doubts, so you can see for yourself what the problem is while trying cleaning them.

Second, the use of Combofix in the Am I Infected forum is not allowed and will not be discussed. Note that the disclaimer states that Combofix should NOT be used without guidance of a properly trained malware helper. Combofix is not a toy and can cause many problems when not used properly.

I will request this topic to be closed. If you have other problems, please start a topic in the appropriate forum.

regards, Elise

Hello Warpath,
As stated above, Combofix is not a toy nor an everyday tool. The fact that you have a Virut infection in itself is an indication that you might be relying on Combofix to keep your machine clean. This is not the intended use for Combofix, and if used incorrectly you can cause severe damage to a clean machine.

Please read the information available about Combofix, and PLEASE follow the site rules as posted. In a nice big box right above the reply box you used to post in this forum it states do not run Combofix, or post any logs pertaining to Combofix.

PEV log removed.

Thank you for helping elise025. This topic is now closed.
