Hi all,

A few days ago my computer started disconnecting from my router with win32 error and redirects in firefox. I am not sure which scan but one of them identified Vundo and deleted it. other than the tracking cookies that is all that was found. Although spybot identified lac97inf.sys as a trojan but I read that this is a false positive and macafee rootkit detective showed pctefadata, but I did not delete these. Spyware doctor found spyware possible website hijack but I also read this is a false positive. I have ran malwarebytes, antisuperspyware, hitman, spyware doctor, adaware, spybot, tdsskill, panda rootkit, macafee rootkit detective, f-secure rootkit.

My computer now boots up slower, 2 to 3x, than it used to, this has occured since after restarting from safe mode. I used TFC to clean out my files and firefox and explorer are way slower than they used to be but seem to be getting faster. All other problems are gone.

My question is could I still be infected? Explorer did redirect me to a search assist when I typed in an address but I do not think that address was correct. Other than the computer being slower and laggier, I have not run into any problems so far.

Are there any more scanning utilities that would be beneficial to see if something else is hidden?

Thank you all for what you do!

There are no guarantees or shortcuts when it comes to malware removal, especially when dealing with rootkits. Infections and severity of damage will vary. The longer malware remains on your system, the more time it has to download additional malicious files. Depending on the infection you are dealing with, it may take several efforts with different, the same or more powerful tools to do the job. Even then, with some types of malware infections, the task can be arduous and security tools may not find all the remnants.

In any case, I can only go by what the scan logs show (what was detected/removed) and your description of whatever signs or symptoms of infection you are experiencing.

Try doing an online scan to see if it finds anything else that the other scans may have missed.

Please perform a scan with Kaspersky Online Virus Scanner.
-- Requires free Java Runtime Environment (JRE) to be installed before scanning for malware as ActiveX is no longer being used.
-- This scan will not remove any detected file threats but it will show where they are located so they can be cleaned with other tools.
  • Vista/Windows 7 users need to run Internet Explorer as Administrator.
    To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Read the "Advantages - Requirements and Limitations" then press the Posted Image... button.
  • You will be prompted to install an application from Kaspersky. Click the Run button. It will start downloading and installing the scanner and virus definitions.
  • When the downloads have finished, you should see 'Database is updated. Ready to scan'. Click on the Posted Image... button.
  • Make sure these boxes are checked. By default, they should be. If not, please check them and click on the Posted Image... button afterwards:
    • Detect malicious programs of the following categories:
      Viruses, Worms, Trojan Horses, Rootkits
      Spyware, Adware, Dialers and other potentially dangerous programs
    • Scan compound files (doesn't apply to the File scan area):
      Archives
      Mail databases
  • Click on My Computer under the Scan section. OK any warnings from your protection programs.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • Once the scan is complete (the 'status' will show complete), click on View Scan Report and any infected objects will be shown.
  • Click on Save Report As... and change the Files of type to Text file (.txt)
  • Name the file KAVScan_ddmmyy (day, month, year) before clicking on the Save button and save it to your Desktop.
  • Copy and paste (Ctrl+C) the saved scan results from that file in your next reply.
-- Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished. If that's the case, please refer to How To Temporarily Disable Your Anti-virus.

  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

How is your computer running now? Are there any more signs of infection?...strange audio ads, unwanted pop-ups, security alerts, or browser redirects?

It seems back to normal. Actually it runs a little better than it did before, I guess from emptying all the unnecessary files out. I am still getting the possible browser hijack in spyware doctor pointing to 127.0.0.1 www.usagc.org and the trojan lac97inf.sys in spybot. Should these be ignored as I have read they are more than likely false positives?

I have also ran GMER which did not show anything (no red lines in the results).

Thanks

I'm not sure where you read the information about false positives so I cannot comment without further details.

To confirm or get a second opinion, submit detected files to one of the following online services that analyzes suspicious files:In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.

For submission to a specific anti-virus vendor, please see:

Well, last night I ran a scan while I was not sleeping and this morning it would not come out of the screensaver completely, just got the mouse pointer and background,no icons (has happened before throughout the years) so I rebooted. Now firefox is extrememly laggy with a lot of not responding. I tried for about 20 minutes browsing and it would take around a minute to loads sites. Last night this computer was running perfect. I am still working on it. I have 2 computers and the one I am on now, the internet is running fine so it isn't my ISP.

Have any suggestions?

here is a link to the lac97inf.sys problem: http://forum.avast.com/index.php?topic=34712.0

I will have to dig up the other one.

last night I ran a scan while I was not sleeping and this morning it would not come out of the screensaver completely,

I recommend doing scans with the screensaver, hibernation or Sleep Mode turned off since those features can sometimes have odd effects when attempting to resume normal mode.


I can only go by what the scan logs show (what was detected/removed) and your description of whatever signs or symptoms of infection you are experiencing. If you want a more detailed look at your system, then more advanced tools are needed to investigate. Before that can be done you will need you to create and post a DDS log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help".
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.
When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the Malware Response Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the Malware Response Team.

You're welcome.

Now that your log is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Response Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process or make things worst which would extend the time it takes to clean your computer.

From this point on the Malware Response Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic until you are cleared by the Malware Response Team. If you still need assistance after your log has been reviewed and you have been cleared, please PM me or another moderator and we will re-open this topic.

Good luck with your log.
