I have a red file pop up on the aswmbr scan and then it looks like it gets hung up.

Doesn't want to finish.  Unitywebplayerupdate.exe is the one it is stuck on.

Hi jackal13,


Download ComboFix from one of these locations:

Link 1 (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)


* IMPORTANT !!! Save ComboFix.exe to your Desktop

When finished, it shall produce a log for you.  Please include the C:\ComboFix.txt in your next reply.

Notes:

1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
3. If after running combofix you recieve an message "Illegal operation attempted on a registery key that has been marked for deletion" or similar reboot the computer.
4. CF disconnects your machine from the internet.  The connection is automatically restored before CF completes its run.  If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

Please post back with the combofix log.

Thanks

Hi jackal13,

Log looks good.

BitTorrent
You have BitTorrent, a P2P/file sharing program installed on your computer. P2P applications like it are the largest source of malware we see. You'll be doing yourself a favor by removing it.

References for the risk of these programs can be found in these links:
http://www.microsoft.com/windows/ie/commun...protection.mspx (http://www.microsoft.com/windows/ie/community/columns/protection.mspx)

http://www.internetworldstats.com/articles/art053.htm://http://www.techweb.com/wire/1605005...cles/art053.htm (http://www.internetworldstats.com/articles/art053.htm)

I would recommend that you uninstall BitTorrent, however that choice is up to you. If you choose to remove this program, you can do so via Control Panel >> Add or Remove Programs.

If you wish to keep it, please do not use it until your computer is cleaned.


Your java is out of date. Click your start button > Control Panel
Code: [Select]
:Services

:Commands
[emptytemp]
[createrestorepoint]

Then click the Run Fix button at the top
Next

One more scan to check for stragglers.

As a Vista/Win7 user you will need to right click your browser icon and select "Run as Administrator" in order to run this scan.*Note
It is recommended to disable onboard antivirus program and antispyware programs while performing scans so there are no conflicts and it will speed up scan time.
Please don't go surfing while your resident protection is disabled!
Once the scan is finished remember to re-enable your antivirus along with your antispyware programs.



Go here to run an online scannner from
ESET  (http://www.eset.eu/online-scanner)

(Note: You can use Internet Explorer or FireFox for this scan. If you use FireFox you will be asked to install an additional component. Please allow this.)

Note - when ESET doesn't find any threats, no report will be created.

Hi jackal13

How's the computer?

Just a couple of files to remove, the rest are files we have all ready quarantined or are in system restore. These will be removed when we remove the tools.



Next, Double click on OTL.exe
Code: [Select]
:Services

:Files
C:\Users\All Users\Tarma Installer\{2E1037EA-038A-425F-86B9-6CD19B8497E9}\_Setupx.dll

:Commands
[emptytemp]
[createrestorepoint]

Then click the Run Fix button at the top
Please post the  OTL  fix log.

Hi jackal13,

I do believe you are good to go.

We'll clean up the tools now.

From your desktop, please delete, if present
Next

Click the Start button. Copy and paste the following line into the search box and click OK


Combofix /uninstall


Next

Open OTL then click the Clean Up button. You may get prompted by your firewall that OTL wants to contact the internet -  allow this.  A cleanup.txt will be downloaded, a message dialog will ask you if you want to proceed with the cleanup process, click Yes. This will do some clean up tasks and delete some of the tools you have downloaded plus itself.

I suggest you keep MBAM. Keep it updated and use it regularly.

Some Recommendations and prevention tips

Basic security consists of 1 antivirus program, 1 resident antispyware program, 1 on demand antispyware program and a firewall. Those you have now provided you are using a firewall. Windows 7 has a built in firewall which is pretty good when set up. You can find some very good information HERE (http://www.addictivetips.com/windows-tips/windows-7-firewall-outbound-protection/) .

You should also use Spyware Blaster (http://www.javacoolsoftware.com/spywareblaster.html) to help immunize your computer.

 - SpywareBlaster will add a large list of programs and sites into your Internet Explorer
settings that will protect you from running and downloading known malicious programs.
 
OR

A guide to understanding and using the hosts file.

Learn how your Hosts file can protect you and how you can protect it.
Besides the Hosts file information, there are links to a very good updated hosts file, a host file manager. and some programs that can protect your hosts file.
HOSTS (http://www.mvps.org/winhelp2002/hosts.htm)

Please read the info on disabling the DNS Client before installing a custom hosts file.

-Secure your Internet Explorer

From within Internet Explorer click on the Tools menu and then click on Options.Next press the Apply button and then the OK to exit the Internet Properties page.

- Make sure you have reset Windows Updates to your chosen option. Click your start button > Control Panel > System > Windows updates (lower left) > change settings

- Keep your antivirus program updated, as well as any other security programs you have.

-More tips and programs can be found HERE (http://forums.whatthetech.com/Preventing_Malware_Tools_Practices_Safe_Computing_t98700.html)

 Please post back if you have any problems.

Take care
