Try:

sc   config   WCNCSVC   start=   disabled

No space between start and = 

 

Do you have a Smart TV?  Or perhaps your neighbor has one?

I do have a Samsung-TV however I have not connected it to the wifi yet.

I got an access denied error when I tried to disabled it. Also, to note is I have a file as the first file on the c. /drive labeled 5a4f29c64189942195 which gives me not authorized to access file. I am logged in as administrator. Food for thought

Ok I reentered the commands and recieved success. Rebooted and nothing has showed up in my network. Still don't have access to that file at top of the c/drive tree. How can I be sure there is nothing lurking?

5a4f29c64189942195 is probably a windows update.  You normally don't see them since Windows hides them.  If you right click on it and select Properties then Security you will probably see that it is owned by TrustedInstaller.  They are supposed to go away after the update is installed but sometimes they stick around.  You would have to take ownership of the file in order to delete it.

So do you think it is safe set up a new wifi, email and user names? Thinking about reinstalling Kaspersky just in case.

I don't see any problems.  Kaspersky is probably the best anti-virus out there.  Make sure you change the default passwords on your router.  

 

Time to clean up:
 
To delete the Quarantine Folder used by FRST create a fixlist.txt file with just the following line:
 
DeleteQuarantine:
 
Save the fixlist.txt to the same folder as FRST then run FRST and hit Fix.  You can easily delete any other folders and logs.
 
If we installed Speccy it needs to be uninstalled.  Process Explorer, VEW, AdwCleaner, JRT  and their logs and Speccy's log can just be deleted.
 
Also make sure you have the latest versions of any adobe.com products you use like Shockwave, Flash or Acrobat.  Flash is now the most malware targeted program so it must be kept up to date.  Be careful with Adobe.  They are fond of offering optional downloads like yahoo or Ask toolbars or that worthless McAfee Security Scan.  Go slow and uncheck the optional stuff.
 
Whether you use adobe reader, acrobat or fox-it to read pdf files you need to disable Javascript in the program.  There is an exploit out there now that can use it to get on your PC.  For Adobe Reader:  Start, All Programs, Adobe Reader, Edit, Preferences, Click on Javascript in the left column and uncheck Enable Acrobat Javascript.  OK Close program.  It's the same for Foxit reader except you uncheck Enable Javascript Actions. 
 
If you use Chrome/Firefox/Safari then get the Ublock Origin add-on from:  https://www.ublock.org/
Doesn't work on IE so for IE get the AdBlock Plus program.  Go to adblockplus.org
 
If Chrome/Firefox is slow loading make sure it only has the current Java add-on.  Then download and run Speedy Fox.
http://www.crystalidea.com/speedyfox.  Close Chrome/Firefox/Skpe. Hit Optimize.   You can run it any time that Chrome/Firefox seems slow starting..
 
To prevent a relatively new phishing attack:  In Firefox, type:
 
about:config
 
in the URL box and hit Enter.  You should get a new page of options (if you get a notice about voiding the warranty just cancel the warning).  In the Search box put in 
 
puny
 
You should only get one option:
network.IDN_show_punycode
We want it to say True but by default it is False so double click on it to toggle from False to True.
Close and restart firefox.
 
To test it you can go to:
 
 
If the value is false you will see https://www.apple.cominstead of the correct value
 
 
If you are a Facebook user get the FB Purity extension for your browser:
This will stop all of the suggested pages and ads so that Facebook loads much quicker.
 
 
Be warned:  If you use Limewire, utorrent or any of the other P2P programs you will probably be coming back to the Malware Removal forum.  If you must use P2P then submit any files you get to http://virustotal.combeforeyou open them.
 
Due to a recent rise in the number of Crytolocker infections I am now recommending you install:
 
CryptoPrevent
 
 
The free version does not update on its own so you should check for updated versions once in a while. When you install it the default is NONE which is kind of worthless so change it to Standard or default. If you have problems after installing CryptoPrevent you can just uninstall it.
 
If you have a router, log on to it today and change the default password!  If using a Wireless router you really should be using encryption on the link.  Use the strongest (newest) encryption method that your router and PC wireless adapter support especially if you own a business.  See http://www.king5.com...0637284.htmlandhttp://www.seattlepi...ted-1344185.php for why encryption is important.  If you don't know how, visit the router maker's website.  They all have detailed step by step instructions or a wizard you can download.
 
Special note on Java.  Old Java versions should be removed after first clearing the Java Cache by following the instructions in:
Then remove the old versions by going to Control Panel, Programs and Features and Uninstall all Java programs which are not Java Version 7 update 25 or better.  These may call themselves: Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, J2RE, J2SE.  Get the latest version from Java.com.  They will usually attempt to foist some garbage like the Ask toolbar, Yahoo toolbar or McAfee Security Scan on you as part of the download.  Just uncheck the garbage before the download (or install) starts.  If you use a 64-bit browser and want the 64-bit version of Java you need to use it to visit java.com.
Due to multiple security problems with Java we are now recommending that it not be installed unless you absolutely know you need it.  IF that is the case then go to Control Panel, Java, Security and slide it up to the highest level.  OK.
 
 
My help is free but if you wish to show your appreciation, please donate to Kwiaht instead of me. It's an Orcas Island environmental organization that I volunteered with: http://www.kwiaht.org/donate.htm
(The name means something like "clean place" in one of the local native-American dialects)

Ron,
One more thing I did one last RogueKiller scan and it detected two DNS Registry inputs. They are both dealing with the DHcp Name sever. Let me know what you think and if you want to see the report.

Rogue Killer always reports DNS so we can check it but in this case it turns out to be Cox Communications ISP so I assume you are in or near Atlanta and that it is OK.
