Download GMER Rootkit Scanner from here to your desktop. It will be a randomly named executable.
  • Double click the exe file.
  • If it gives you a warning about rootkit activity and asks if you want to run scan…click on NO, then use the following settings for a more complete scan.


    [external image: Posted Image]
    Click the image to enlarge it


  • In the right panel, you will see several boxes that have been checked. Ensure the following are unchecked
    • IAT/EAT
    • Drives/Partition other than Systemdrive (typically C:\)
    • Show All (don't miss this one)
  • Then click the Scan button & wait for it to finish.
  • Once done click on the [Save..] button, and in the File name area, type in "Gmer.txt" or it will save as a .log file which cannot be uploaded to your post.
  • Save it where you can easily find it, such as your desktop, and attach it in reply.

**Caution**
Rootkit scans often produce false positives. Do NOT take any action on any "<— ROOKIT" entries

alright attached is the following: DDS.txt Attach.txt. Gmer.txt btw you can call me an idiot or somthing but being the impatient person i am, i went ahead and used combofix which SEEMS to have fixed the problem but AVG picked up the virus but its not doing anything. Sorry for adding more inconvenience to the problem : ( ps. do you want the log?

Hi


P2P - I see you have P2P software utorrent installed on your machine. We are not here to pass judgment on file-sharing as a concept. However, we will warn you that engaging in this activity and having this kind of software installed on your machine will always make you more susceptible to re-infections. It likely contributed to your current situation. This page will give you further information.
Please note: Even if you are using a "safe" P2P program, it is only the program that is safe. You will be sharing files from uncertified sources, and these are often infected. The bad guys use P2P filesharing as a major conduit to spread their wares.
Please see this topic for more information:
Perils of P2P File Sharing.
I would strongly recommend that you uninstall this now. You can do so via Control Panel >> Add or Remove Programs.

Run an on-line scan with Kaspersky

Using Internet Explorer or Firefox, visit Kaspersky On-line Scanner

1. Click Accept, when prompted to download and install the program files and database of malware definitions.
2. To optimize scanning time and produce a more sensible report for review:
  • Close any open programs
  • Turn off the real time scanner of any existing antivirus program while performing the online scan
3. Click Run at the Security prompt.
The program will then begin downloading and installing and will also update the database.
Please be patient as this can take several minutes.
  • Once the update is complete, click on My Computer under the green Scan bar to the left to start the scan.
  • Once the scan is complete, it will display if your system has been infected. It does not provide an option to clean/disinfect. We only require a report from it.
  • Do NOT be alarmed by what you see in the report. Many of the finds have likely been quarantined.
  • Click View scan report at the bottom.

Hi

Try this scanner instead:

Go here to run an online scanner from ESET.
  • Note: You will need to use Internet explorer for this scan
  • Turn off the real time scanner of any existing antivirus program while performing the online scan
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the activeX control to install
  • Click Start
  • Make sure that the option Remove found threats is unticked and the Scan Archives option is ticked.
  • Click on Advanced Settings, ensure the options Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  • Click Scan
  • Wait for the scan to finish
  • Use notepad to open the logfile located at C:\Program Files\Eset\Eset Online Scanner\log.txt
  • Copy and paste that log as a reply to this topic and also let me know how things are now.

Post #13

out of curiosity what would you have done if THIS scan didnt work?


:lol:

I still had lot's of options available, there's always something else to try.

Well, nothing was found anyway, just a cookie, which you get just by connecting to the internet.

so how is the computer running? Are there any outstanding issues?

Please post a fresh DDS log and Attach.txt
Post #14
Well the only issue now is the degenerating connection. I.e. the computer for the first 3 hours or so is fine but after that internet gets laggy, then internet doesnt stream youtube, then internet just quits and it takes 1-2 minutes to load a page while my netbook/laptop run just fine. But i think its just my wireless card being over worked. Nonetheless can you take a look for me? that would be most apprietiated attached: attach.txt dds.txt
