Download ALL of the tools below on a friend or family member's, CLEAN computer and copy them to a CD or flash drive, then transfer them to the problem machine.

First, after transferring it to the problem machine, run the following tool to help allow the removal programs below to run. (courtesy of Grinler at BleepingComputer.com)
There are 4 different versions. If one of them won't run then try to run the other one. Be patient.... as a black window should open, then close after finding all the background programs.
Vista and Win7 users need to right click and choose Run as Admin
You only need to get one of them to run, not all of them.

Rkill.exe http://download.bleepingcomputer.com/grinler/rkill.exe
Rkill.com http://download.bleepingcomputer.com/grinler/rkill.com
Rkill.scr http://download.bleepingcomputer.com/grinler/rkill.scr
Rkill.pif http://download.bleepingcomputer.com/grinler/rkill.pif
_____________________

IMMEDIATELY after running the "Rkill" tool above, run/install the Malwarebytes and SuperAntispyware installer and update files from the links below which you've also copied to a CD or flash drive, and transfered to the problem machine. Do NOT restart the computer after running Rkill.

Once downloaded and before transferring Malwarebytes and SuperAntispyware to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)
http://www.besttechie.net/tools/mbam-setup.exe

Malwarebytes Manual Updater link
http://www.malwarebytes.org/mbam/database/mbam-rules.exe

Next, install and run a full system scan with the SuperAntispyware program and the manual updater from the links below. As before, you may need to rename the installer file to get the program to install.:

SuperAntispyware
http://www.superantispyware.com/

SuperAntispyware Manual Updater
http://www.superantispyware.com/definitions.html
____________

In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder....

If Malwarebytes Will Update and Run Correctly After Rkill...
by Grif Thomas Forum moderator / May 1, 2010 3:04 AM PDT
In reply to: malware anti malware

..then there's no need to reinstall it. If it doesn't run correctly, then and uninstall/reinstall may be necessary. In addition, please install SuperAntispyware as well. You'll want the "second opinion that it gives during its scan. It frequently finds things that Malwarebytes doesn't.

Hope this helps.

You'll Want To Temporarily Disable System Restore
by Grif Thomas Forum moderator / May 2, 2010 5:23 AM PDT

It's a little strange that the files are found in the D: drive, (usually a recovery partition and it explains why they're hidden because such are usually hidden partitions), but either way, the System Volume folders contain files for your System Restore tool.. Those particular folders are "locked" by System Restore and as such, removal tools have difficulty getting rid of them.. So, to be sure they're gone, try temporarily disabling System Restore, restart the computer, then re-enable SR again.. Use the instructions in the link below to accomplish the task.

How To Disable System Restore

Hope this helps.

Well, Torrents Are Problems In General
by Grif Thomas Forum moderator / May 3, 2010 5:54 AM PDT
In reply to: :).....:(

First, such downloads have a high rate of infection..

Second, if Firefox doesn't work right, try uninstalling it, then reinstalling it.. Or try a different browser.. Does Internet Explorer work find? If not infection is being found, the computer may be clean but damage may have been done to a variety of programs. Some have found it necessary to perform a full reformat and reinstall of everything. Others are able to narrow down the specific issues and fix them one by one.. Only time will tell which path you will need to take.

Hope this helps.

i have 3 browsers google chrome,firefox, ie8, and firefox shows


This Connection is Untrusted











You have asked Firefox to connect
securely to login.yahoo.com, but we can't confirm that your connection is secure.



Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.
What Should I Do?


If you usually connect to
this site without problems, this error could mean that someone is
trying to impersonate the site, and you shouldn't continue.
Technical Details
login.yahoo.com uses an invalid security certificate.
The certificate is not trusted because the issuer certificate is not trusted.

Wait It Out... Or A Few Things To Try..
by Grif Thomas Forum moderator / May 4, 2010 2:02 AM PDT

There may be a couple of reasons you're experiencing the certficate error.(Yahoo's login works fine in the latest Firefox 3.6.3 version here.) Try the suggestions below:

First, try emptying all Cookies, History, and Cache from the Firefox, "Tools-Options-Privacy tab".

Next,....

Try using the link below to log into Yahoo:

https://login.yahoo.com/config/login_verify2?.intl=us&.src=ym

Does it work correctly?

Or troubleshoot the issue using the Mozilla link below:

Hope this helps.

ONLY in Regard to Win.MSSQL.worm.Helkern
by Carol~ Moderator / April 26, 2010 10:40 AM PDT

FYI and FWIW:

It is noted here at the Kaspersky Lab Forum: 'This kind of intrusion is dangerous only for those using "Microsoft SQL Server 2000". However KIS automatically blocks the attack'. Are YOU using "Microsoft SQL Server 2000"?

From Frequently encountered messages at the Kaspersky Lab Forum:

Win.MSSQL.worm.Helkern

1)What is Helkern?
Helkern is an internet worm, that exploits a vulnerability in Microsoft SQL server 2000.
You can find more about it here or here

2)Who is attacking me and why?
These attacks are made by the malware which tries to infect other vulnberable PCs. They are automated and target random PCs. The so called attacking PCs are mostly victims of the malware themselves.

3)How can i protect myself?
First of all the Intrusion Detection System (IDS) in KIS blocks it, so you are safe. When the IDS blocks such an attack you will get a notification like this one:

See THIS NOTIFICATION.

Even without the IDS to block the attack only some PCs are vulnerable to it, PCs running SQL Server 2000 that aren't patched against this vulnerability.

This is why you should keep your pc updated. Not only against this form of malware but also others.

4)How can i get rid of this notification?
If you find this notification annoying then you can easily disable it, by clicking on the arrow pointing downwards in the notification and selecting "Disable this notification".

See how to : DISABLE THIS NOTIFICATION
