      Bitdefender Business Support Forum Rules - Read carefully before posting   09/13/2016

      Bitdefender Business Support Forum Rules (PLEASE READ BEFORE POSTING) In order to post to the Official Bitdefender Support Forums, you will need to register using a valid email address, and following the instructions to validate your membership. If you like to register, click here. GENERAL RULES Understand that once you have registered as a new user, you consequently agree with ALL THE FORUM RULES written below. These rules were designed to ensure you get the most from interacting with other users in a pleasant and constructive manner and to prevent any sort of abuse. 1. First and foremost, this is a support forum for Bitdefender. Do NOT post comparative tests for security software for they are unrelated to the main character of the forum. Also, the support process can take many forms: a troubleshooting routine is meant to locate the cause of the issue not offer a permanent solution –do NOT post replies in the form of "I need a fix now" instead of the information requested for without locating the cause there isn't any way to implement a fix. 2. Once an official position has been posted concerning a bug in Bitdefender and the ETA for the fix, the topic will be closed down. Do not ask for the topic to be reopened unless you still have the bug after the update targeted to handle this issue. 3. Users that have reached a 50% warn level will have their posts subjected to moderator approval and if they continue to ignore forum rules their account will be banned. 4. Users are not allowed to use clones(using more than one account by a single person). Breaking this rule will lead to a permanent IP ban. 5. Users are not allowed to use anonymous proxy. Breaking this rule will first result in a warning, followed by subjecting the user's posts to moderator approval/banning of the account. 6. When reporting an issue concerning Bitdefender make sure to offer the following basic information: - name and version of your Bitdefender product; - name and version of your Operating System; - the complete error message (if any) that you receive and, if possible, attach a screenshot with it; - name of other security solutions that you are running; - when asking questions about (un)detected files (false alarms, or files that you suspect to be infected, but aren't detected), please attach a complete Bitdefender scan log. Be sure to keep Bitdefender fully updated so the log contains accurate info – on the support forum we only accept the posting of scan logs, for sample submission of false positive/false negative samples please upload them onto a web based platform where we can retrieve and analyze them. 7. Topics related to the lack of response from the support department need to be backed up by as much information as possible concerning the issue that you have been facing. When you send an e-mail to support a Ticket ID will automatically be created - make sure to mention it in the forum post for it will speed up the entire process. 8. Moderators do NOT offer support by PM. Do not send personal messages to moderators unless they expressly request it from your side/ you wish to have a closed topic re-opened/ you wish to report a forum member or topic for abusive language or spam/ you are unsure as to posting a possible solution and you wish to consult with a moderator first. All users are treated as equal on this forum and by sending a PM to a moderator you will not be entitled to faster support. In case of rule violation reports, you can also use the built-in Report button to announce all moderators that there's a topic/post/user that violated the posting rules. Please do NOT use this function to ask for help, or announce the moderating team that you need urgent support! As said, all issues are handled as fast as possible, and none has priority over another. 9. Any form of aggressive language, directed at other forum members or at the Bitdefender Moderating Team or staff is completely forbidden. Continuous attacks will result in an account suspension or BAN. Also, any form of explicit, antisemitic or racial language, or social attacks (by images, text, PMs, signature, or any other form of communication on Bitdefender forum) will NOT be tolerated and will result in an immediately account BAN. Take into consideration that this forum a public place. Treat everyone else just like you want to be treated. 10. Users are not allowed to open polls on the Bitdefender Support Forum. The only members that are allowed to open polls are the moderators. FORUM SIGNATURES, AVATARS AND DISPLAY NAMES The signature is optional on the forum, and should be a personal message of the user that chooses it. Moderators are obliged to include a link for the Bitdefender Forum Rules in their signature. Users will only be allowed to display a custom signature after having completed 15 posts on the forum. The following will NOT be tolerated: 1. Any type of explicit reference to the brand name and symbols of other security solutions available on the international market today, except Bitdefender. This is a support forum dedicated only to Bitdefender and advertising competitor products will lead to editing out the advertisement and a 20% increase in the warn level. 2. The use of images higher than 300 pixels width and/or 100 pixels height. 3. The use of images or text containing the words "Moderator", "Administrator" or "Admin" in the signatures. These will only confuse other users. 4. The use of images taken from other users of this forum. Please use unique avatars. 5. Use of signatures pointing to external links,they will be removed without any notice. WARNINGS Those who repeatedly violate these rules will receive a warn/suspend/ban. POSTING RULES 1. Topic titles must be as concise as possible, and starting posts must provide relevant information on the issues included, to ensure a fast and precise response from those who are willing to help. For example: avoid titles such as "Heeeeeelp!" but instead write "Question about the Bitdefender Antivirus". The last title has a lot more chances of receiving fast responses. Also, topic titles such as "Program X ######! " together with the lack of any constructive arguments will not be tolerated, the topic will be deleted and the user will receive a 20% warning. 2. Post new topics in the correct sections. The forum is structured by Product type (Home/Office or Business protection) and by product version (2008, 2009, 2010 or older versions). If you post the question in the correct section, you have a higher chance of getting a correct answer for your problems. 3. Bumps/Topic advertisements or any other attempts to make a topic more visible without adding any new or relevant information will NOT be tolerated and the post will be DELETED. 4. When posting a reply on a topic try to keep the suggestion within a relevant range – for example, when there is a post concerning an error message in Bitdefender 2009 do not recommend downgrading to Bitdefender 2008 for this suggestion does not address the original issue. Multiple posting of this type will lead to an increase of the warn level with 20%. 5. Off-topic replies (those that have nothing to do with the topic) will be deleted, and users will also receive a written warning . Repeated posting of off-topic replies will lead to an increase in the warn level with 10%. 6. Keep text color, fonts and letter casing within a normal and pleasant range - any post that contains only upper case text will automatically be subjected to editing, the same applies to posts containing characters larger than size 20. 7. Before opening a new topic, we strongly suggest that you use the SEARCH button, to be sure that the problem was not already discussed. In case you start a new topic with an issue that was already discussed, the new topic will be closed down, redirected and merged into the initial one. 8. Do not ask the same thing on more sections of the forum. Do not post the same topic more than once. Twin topics will be removed and redirected to the original one in order to avoid confusion. 9. Do NOT request/post warez software, cracks, serial numbers or any other actions which involve software piracy. Topics and replies related to cracking security software, advice on breaching security systems, cracking security protocols, flood attacks or posts that promote cracking or Internet attacks in any way will be deleted at once and the users that posted them will have their accounts suspended at once. Also, no support will be offered for users that are using a cracked version of BitDefender on their systems. 10. Please avoid topic titles such as "URGENT" since all cases are treated as soon as possible. 11. Be patient – there are a lot of issues on the forum and we are doing the best we can to answer them all. Therefore, you may receive your answer immediately, but it may also take several days just as well. 12. We do not allow people to post threads that advertise or solicit any products, services, funds or donations – all topics of this type will be automatically DELETED . Explicit advertising is also prohibited. FORUM RULES ARE SUBJECTED TO CONTINUOUS MODERATION AND CAN BE CHANGED AT ANY GIVEN TIME WITHOUT PRIOR NOTIFICATION. ANY TOPIC DEBATING FORUM RULES WILL BE CLOSED DOWN AND AUTOMATICALLY DELETED FOR THESE RULES ARE NOT SUBJECTED TO DEBATE. Bitdefender Business Support Forum Team

Rootkit.mbr.pihar.f (boot Image); Trojan.iframe.aip

Re: Windows XP Pro, SP3

I upgraded from BD Ativirus 2009 to 2012. Without any scan, the first event BD 2012 detected was:

File: C

Action Taken: Deny

Date: April 10, 2012

Virus Name: Rootkit.MBR.Pihar.F (Boot image)

Other subsequent events showed that the Autoscan was being turned off and then on --again and again.

I ran a deep system scan and it ran for about 5 minutes and then everything halted and poof, it gave me the blue screen of death with the usual message. I rebooted with the on/off switch into the last known configuration that worked, ran another deep system scan and no threats were detected.

First, what does “deny” mean? Who/what is denying what, and to whom?

Second, how do I get rid of the Rootkit virus?

Third, what is with the on/off of the Autoscan?

P.S. My problems started when BD AV 2009 detected a Trojan.Iframe.AIP virus that it was unable to disinfect -- some were deleted. The PC kept pinging me with the windows “asterisk” sound and it created 2,800 junk files in one of the Content.IE5 subdirectories, and hundreds of junk files in the other Content.IE5 subdirectories. Using Unlocker, I managed to delete most of these junk files – even as the virus was creating them right before my eyes, as fast as I could delete them. However, the pinging is still around and file creation seems to still be going on, but no more Iframe has been detected.

I tried the 32 bit Bootkit removal tool mentioned above and it gave zero files cleaned from zero infected files. It has been tested on the *.A thru *.D, but not the *.F variant file.

Re: my Ticket ID:201204061029276

Is this the solution [except do for XP, not Vista]?

Restore the MBR (Master Boot Record) of your hard disk using the Windows CD.

the command that you need to run is: fixmbr

Full info is available here: http://helpdeskgeek.com/how-to/fix-mbr-xp-vista/

I saw where forum member "walkerbraces" did this and still had the Bootkit. He then ran a BDSYS log. but the BDSYS log I ran as the first suggestion gave me the blue screen of death.

Hello :)

Welcome to the forums.

For the MBR infection, that is the solution, fix the MBR using the Windows CD.

It's the only way to do it and it's the safest.

Let me know if you have other questions.

Take care.

Christian, so what action was taken by BD as described by the word "deny"?

Has BD made changes such that access to the the offending file is now "denied" so that it now no longer poses a threat?

OR...was BD "denied" access to the file, thereby preventing BD from doing any operations on the file, and it therefore continues as a threat?

The 2 blue screen tech infos mentioned Kdcom.dll and iAstor.sys. Do I need to safe-mode delete these files or what?

Christian:

I disabled BD On Access Scanning and ran the tool

(http://www.malwarecity.com/blog/free-removal-tool-for-tdl4-available-now-1106.html)

and got no threats detected.

Earlier this morning I ran a scan on my "C:\Documents and Settings" directory and found one threat: "Gen:Varient.Zusy.Elzob.1758." I deleted this file. Afterwards, all my programs loaded promptly (they just "popped" open) and ran really fast without hanging up like in the past. My PC is now running faster than it ever has in the past!

Also, there is no more pinging of the Windows "asterisk" sound -- I think this meant that something was opening or some operation was executing.

Also I ran a scan on all my Content.ie5 subdirectories and found no threats. One of the subdirectories had over 3,000 junk files and I was able to delete these with the UNLOCKER program.

I just searched all the Content.IE5 subdirectories and no more junk files have been generated and they are all empty except for one index.dat file and one desktop.ini file.

I am going to now run a deep system scan.

QUESTION: Is RootKit.MBR.Pihar.F virus still a threat? Am I good to go?

Please advise.

OK. I did a custom scan that included a target scan for Rootkits and a scan for Boot Sectors and no threats were detected.

I then learned that a deep system scan includes, by default, a Rootkit scan setting and I checked the log of such a scan done yesterday and the Rootkit target found no threats.

So does this mean that the virus Rootkit.MBR.Pihar.F has been deleted? If so then who/what deleted it and when?

Is there a record (log) of the deletion?

Hello :)

Welcome back.

In order to be able to assist you please run a Full System Scan task with Bitdefender and send us the resulting scan report.

[how to GENERATE A FULL SYSTEM SCAN LOG]

- Before running the scan please make sure that you have the latest virus definitions downloaded via the Update module.

For this you need to open Bitdefender and from the main interface click on Update now;

- After the update process has completed successfully you can proceed to

running the scan task.

In the same window go to Antivirus and press the Scan now button =>Full system scan.

- After the scan has finished you need to submit the scan log file.

This is accomplished by running the Support tool file that can be

downloaded from this location:

http://www.bitdefender.com/files/Knowledge...or_scanlogs.exe

Save the file prior to running it and to continue you need to accept the terms of use.

At the end of this process an archive will be created on your Desktop starting with bdamst.

. Send me that file via PM.

Take care.

Christian, all issues appear to have been resolved, and therefore there is no need to send a log file. My PC is running fast with no hang ups or blue screens like before. The virus "Rootkit.MBR.Pihar.F" has been eliminated per email from George Poienaru of your office, which is self-explanatory, copy enclosed below for your information. Thanks for all your help.

Re: "DENY"

I respectfully suggest that you tell your developers to change the "Action Taken: Deny." That message is confusing and tells the user absolutely nothing about what action is taken. The user is left wondering whether or not he still has an infected system.

I suggest "Action Taken: will not be loaded and will be deleted on next boot." Or: "Deletion failed, but will be deleted on next reboot."

Or else put a help "balloon" that says: "Deny" means that BD was unable to delete the file, but that it will prevent the file from loading on the next reboot and it will then be deleted. No log will be created."

Dear Sinbad,

Thank you for your interest in our security solution, Bitdefender.

Every time Bitdefender fails to remove an infected item it schedules the removal for the next boot, when the file is not loaded by the operating system.

Unfortunately these actions are not logged because the logging module is not loaded at boot.

Have a great day!

Best regards,

George Poienaru

As I requested in my message: please tell the developers to consider changing and clarifying the "deny" message in order that the user will understand how Rootkits are detected and what action is taken.

Until then, may the Totemic Essence of the Dragon Wolf safeguard and watch over us all.
