Posted 04 April 2009 - 08:01 AM

This computer i am using rarely goes online and i allways try to keep it patched and virus scan before using. During my last scan a2 (a squared) seems to have found a number of virus's, (i have submitted these files to a2 for verification).

I have also run scans using Kaspersky, Mbam & SuperAntispyware which have come back clean (please see the logs below)

Could some one advise me what to do next.

Thankyou

Chr!s

Hello.

I have also run scans using Kaspersky

Are you referring to the online scan? If you still have the log it would be great if I can see it.

Those may be a false-positive. If Kaspersky didn't find anything it's probably a false-positive. Those files seems to be infected by VIRUT according to a2...

Please run the following scan.

Download and Run DrWebCureIt in Safe Mode

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in Safe Mode using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to start the program.
  • Cancel any prompts to download the latest CureIt version and click Start.
  • At the prompt to "Start scan now", click OK. Allow the setup.exe/driver to load if asked by any of your security programs.
  • The Express scan will automatically begin.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck Heuristic analysis under the Scanning tab, then click OK.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Yes to all if asked to cure or move the file(s) and select Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
With Regards,
extremeboy

Hi,

Sorry, no i didnt use the online scan my local antivirus and firewall is Kaspersky Internet Security2009 (version 8.0.0.506)


Here's the log from my local KIS2009 scan,

Should i do an online kaspersky scan aswell ? Would i have to disable my local KIS2009 before doing an online scan ?



Here's the DrWeb Scan log

140ef.msi\stream003;C:\WINDOWS\Installer\140ef.msi;Trojan.PWS.Wsgame.origin;;
140ef.msi;C:\WINDOWS\Installer;Archive contains infected objects;Moved.;




I dont know if this is relvant i use a wired netgear dg834g router and have been looking at its logs, it seems to get port scans maybe 1 or twice a day, do you think this is just random scans and the router is doing its job or is it being targeted ? (i dont know too much about how it works)

Sat, 2009-04-04 09:27:03 - TCP Packet - Source:61.139.***.*** Destination:86.10.**.*** - [PORT SCAN]
Sat, 2009-04-04 09:27:06 - TCP Packet - Source:61.139.***.*** Destination:86.10.**.*** - [PORT SCAN]

Hello.

I think it is a false-positive by A^2.

Run the following online scan just to make sure.

Run Scan with Kaspersky

Please do a scan with Kaspersky Online Scanner. Please note: Kaspersky requires Java Runtime Environment (JRE) be installed before scanning for malware, as ActiveX is no longer being used.)

If you are using Windows Vista, open your browser by right-clicking on its icon and select 'Run as administrator' to perform this scan.

  • Please disable your realtime protection software before proceeding. Refer to this page if you are unsure how.
  • Open the Kaspersky WebScanner
    page.
  • Click on the Posted Image button on the main page.
  • The program will launch and fill in the Information section on the left.
  • Read the "Requirements and Limitations" then press the Posted Image button.
  • The program will begin downloading the latest program and definition files. It may take a while so please be patient and let it finish.
  • Once the files have been downloaded, click on the Posted Image ...button.
    In the scan settings make sure the following are selected:
    • 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
      By default the above items should already be checked.
    • Click the Posted Image button, if you made any changes.
  • Now under the Scan section on the left:

    Select My Computer
  • The program will now start and scan your system. This will run for a while, be patient and let it finish.
  • Once the scan is complete, click on View scan report
  • Now, click on the Save Report as button.
  • Save the file to your desktop.
  • Copy and paste that information in your next post.
You can refer to this animation by sundavis.

Extremeboy

Everything seems ok untill this point, When i press the accept button i get a popup which says



"The applications digital signature has an error. Do you want to run the application?
Name jReport
Publisher Kaspersky Lab
From http://www.kaspersky.com
[Check box] Always trust content from this publisher
. Run Cancel
The Digital signature was generated with a trusted certificate but has expired."




If i do nothing it goes no further, should i press run ? (does it not seem strange that kaspersky would let a certificate expire)



So far i have checked that java is installed correctly(jre6u13),
I have added www.kaspersky.com to the trusted sites,
i have reduced all ie7 settings to default

I have done a kaspersky online scan on my other pc and it works fine.

Chris


EDIT I dont normally have adobe flash installed, is this required for the online scanner ? as the first page on Kaspersky.com is asking if i would like to install it.

Hello.

I have added www.kaspersky.com to the trusted sites,

Not a good idea. Kaspersky should work without that needed. Please remove it.

Let's try a different online scanner. I will research into that error later as I need to leave soon.

Run F-Secure Online Scan

Please run F-Secure Online Scanner.
This scan is for Internet Explorer only.
  • Go to F-Secure Online Scanner
  • Follow the instructions here for installation.
  • Accept the License Agreement.
  • Once the ActiveX installs, click Full System Scan
  • Once the download completes, the scan will begin automatically. The scan will take some time to finish, so please be patient.
  • When the scan completes, click the Automatic cleaning (recommended) button.
  • Click the Show Report button and copy the entire report in your next reply.
  • Be sure to re-enable any security programs.

Extremeboy

Hi,

I tried 5 times but could not get it to download fully, it would start to download and then the computer would re-boot.

To get it to work i had to uninstall java and KIS2009 and reinstall java jre6u13.

Here's the F-secure online log,

Hi Extremeboy, Everything seems to be running fine now thanks. :thumbsup:

I also re scanned with a2 and it does not find anything now, so i guess they have updated there definitions.


Could i just ask a couple of questions before this thread is closed,

Do you think aSquared has a higher rate of false posatives than the average antispyware ?? (you dont have to anwser this)

What in your opinion is the best software(s) for scanning usb pen drives for virus's/spyware ??


Thanks

Chris

Hello again.

Could i just ask a couple of questions before this thread is closed,

Ask any question you want. The topic won't be closed.

Do you think aSquared has a higher rate of false posatives than the average antispyware ??

Well, I never used a full a^2 software before however, I have used their USB emergency file pack thing. Their softwares are not bad, but I don't find them that great either. Regarding FP, all AV will have FP sometime, but I don't and I don't know too many people who use a^2 that talked about the detection rates or FP they get from A^2 so I'm not too sure.

Here's a link on AV-Comparatives and they talk about each one in detail: http://www.av-comparatives.org/

What in your opinion is the best software(s) for scanning usb pen drives for virus's/spyware ??

You're normal AV, AS or AM program should be fine. MBAM is a good anti-malware program that can find many of the recent flash-drive infections.

Flash-drive disinfector is a tool that prevents certain flash-drive infection.

Download and Run FlashDisinfector
  • Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: Flash_Disinfector will create a hidden file named autorun.inf in each partition and every USB drive plugged in when you ran it. Don't delete this folder. It will help protect your drives from future infection.

I personally don't have a "specific" tool/program to scan for my usb's or any removable drives. I rarely scan with them anyways since I'm fairly sure I don't have any thing bad on it. If I were to scan it, I will use my anti-virus (Avira) and my Anti-Malware (Malware bytes Anti-Malware).

For protection this is what I generally say:

1 AV program (Have real-time protection enabled)
1 FW program (Have real-time protection enabled)
1-2 AS/AM program

Hope that helps.

If there's anything you are unclear of, feel free to ask :thumbsup:

No Problem :flowers:

You should purge a system restore point now.

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.

Good luck! :thumbsup:
