Hi,

Was working a bit w/ Lawrence and he suggested that my problems may be FP's but said I could post here. I spent last Sat in the HJT forum to get cleaned from some other issues. Yesterday, however, my Avast detected the following & called them Rootkits...

A0001119.dll C://System Volume Information\_restore...
swg.dll C://Program Files\Google\GoogleToolbarNotifier\5.1.1309.3...

It reports that they were used last a week prior to my HJT clean up so I am not sure if they have been there, are new or are False P's. I am unable to copy all the info from the Virus Chest. Please let me know what else you need. I did notice something new that appeared in my Sch. Tasks, which is where my other infections were appearing. It is a Google Updater that is suppose to update but says it never does????

I would appreciate any assistance..Thanks!

Hello.

That is a restore point. I'm not exactly sure on that google thing however. If you could give me a complete log via AVG's Computer scanner page and export to .xls file that would be helpful.

Please run MBAM first.

Download and run MalwareBytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

For complete or visual instructions on installing and running Malwarebytes Anti-Malware please read this link

EB,

TY for responding! Forgive my seeming lack of gratitude for your help last week. I did in fact appreciate your help. I always use MBAM & it's been reporting clean. Avast is also clean now that the detected items are in the Chest. I began using Avast, not AVG, after we finished up last week, along with SpywareBlaster & I am now permanently using SuperAS as well. The best way that I can show you my logs is by screenshot as I cannot simply copy & paste from the AV's virus chest. BTW, per Lawrence's advice, I already deleted past restore points & created new. I am trying to send you screenshots but am not sure how. I will post this then try to mail you.

Alan

Hello again.

I see the thread you are talking about. Those appear to be false-positive to me as well.

Regarding that swg.dll, I'm pretty sure it's legit but since your AV is flagging it let's confirm that..

Submit File to Online Scanner

There is a file that I would like you to check out for me using VirusTotal/VirSCAN
  • Open VirusTotal Online Scanner or VirSCAN. If one site is busy or down, try the other
  • At the top of the page you'll see a box.
  • Click browse and find the locating of that swg.dll file in the Google folder, I can't see the WHOLE folder path file so you will need to find it yourself.
  • Wait for the scan to finish.
  • Copy Scanner Results into your next reply.
Regarding that restore point it should be removed once you set a new restore point and remove the older ones. Do the following please, if it doesn't get removed we will try something else.

Create a New System Restore Point<- Very Important

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Hi eb,

What do you mean by "I see the thread you are talking about. Those appear to be false-positive to me as well." ? Are you referring to the google updater in my sch tasks?

Alan

ps.

I don't think I can do what you are asking as I cannot upload a file from my Virus Chest & that is where it is. I can try to check that Google updater program file though.

UPDATE- OK I am copying files & storing file info in a folder on my desktop & am uploading from there. Will this method produce the necessary scan results?

Alan

this is not going to give you what you need....the file being scanned is the notepad txt file, not the actually potential problem file...right?

Hello.

I thought that the file will be in a folder that Avast! quarantines...

Anyways, continue with the system restore point instructions. Just FYI, that system restore point may not be a FP but I think that google related file is. I suggest you delete that restore point if your AV detects more of it even after using cleanmgr to remove the older restore points.

I'm very tired today for some reason and it's actually pretty late here as well so I'll talk to you tomorrow. I don't feel to well, so I don't want to give any further instructions in case it doesn't make sense or is not clear.

With Regards,

eb,

Let me know when you're back...hope you feel better!

What do you make of that Google updater suddenly appearing in my Scheduled Tasks? If you don't recall, that's where the 2 remnants of the infected files that we cleaned last week were showing.

Also, I did system restore work yesterday.

Look forward to hearing from you tomorrow.

Alan
