Hackers Infecting Network Routers



It is being reported that hackers have infected 500k routers with malware (VPNFilter) worldwide. The attacks are designed to collect login credentials, gain supervisory control and disable the device entirely. Antivirus provider Symantec issued its own advisory Wednesday that identified the targeted devices as:

Linksys E1200
Linksys E2500
Linksys WRVS4400N
Mikrotik RouterOS for Cloud Core Routers: Versions 1016, 1036, and 1072
Netgear DGN2200
Netgear R6400
Netgear R7000
Netgear R8000
Netgear WNR1000
Netgear WNR2000
QNAP TS251
QNAP TS439 Pro
Other QNAP NAS devices running QTS software
TP-Link R600VPN

In an effort to minimize the effects of the attack, it is advised that users perform a factory reset of their routers. This is typically performed by pressing the reset button for 10 seconds. This will remove any special configuration on the router as well, however. Users should also change the router's password, update the firmware and disable remote administration.

All USB ports stop working after Windows 10 update


This has really been a doosey! Thanks, Mr. Roberts. :) The symptoms of this issue is that all the usb ports on the Windows 10 computer do not work which prevent using the keyboard and mouse from working and logging into the computer. The keyboard and mouse do work, however, before Windows loads (ie BIOS settings screen).

The root cause of the problem is a recent Windows update (KB4074588). This was published mid-February 2018 and I'll focus the steps below for this specific problem. I'll cut out many of the troubleshooting steps I did and give you a targeted solution to speed up your recovery for this specific issue. I'll list the easy things to try first that may work then progress to other solutions. The ultimate goal for this problem is to remove KB4074588 and prevent it from re-installing by whatever means you can muster.

Try the easy things first:
  • Use remote access to remove the update by the normal method (if remote access had been previously configured)
  • Attempt to restore your pc to an earlier date when it was working properly
  • Try booting into Safe Mode and removing the upgrade
That's about all the easy things to try that may actually work. Now on to the the solution that worked for me. 

To perform these steps you need to get your pc to the Windows Command prompt in the diagnostic mode either using a boot disk or turning your pc on and off (push power button when the Windows logo is displayed) 3-4 times. That will launch the built-in diagnostic screen. Follow the on-screen menus to eventually get to the Command Prompt.

Once at the command prompt, enter the command below on one line then press enter:
  • dism /Image:c:\ /remove-package /packagename:Package_for_RollupFix~31bf3856ad364e35~amd64~~16299.248.1.17
The package will be uninstalled. It may state that an error has occurred and no changes were made but most likely it has been removed. 

You will likely be able to login to Windows now but you're NOT DONE yet. Go ahead and log in and do the victory dance! It's down hill from here. Once you're in, go immediately to Windows Update and remove KB4074588 via the normal uninstall process. Once that is remove you may need to restart. Almost done.

After restarting, follow the instructions at https://support.microsoft.com/en-us/help/3073930/how-to-temporarily-prevent-a-driver-update-from-reinstalling-in-window to prevent KB4074588 from automatically reinstalling. 

If none of these methods worked for you the last resort is to restore your pc to factory defaults which could result in loss of data if you don't have backups or can't backup the data beforehand. 

I hope this information has helped you in some way and got you working again rather quickly. As always, feel free to contact me if you need assistance. www.georgephillipscomputerservices.com

Password this and Password that. Tired of getting locked out and resetting passwords?

If you're like me then you have too many passwords to keep straight. These days we have passwords for various shopping sites, our banking websites, our email accounts and on it goes. Sure, some of those websites will allow you to save the password so you don't have to enter it each time but then.....one day it happens. Either the cache is cleared and the passwords are no longer available or we have device trouble which requires us to enter the password. Since we haven't been entering the password regularly it's likely that we'll have to go through the password reset procedures. That process could be repeated through the year many times among the various websites and becomes very frustrating.

We could use one password for everything but that leaves us vulnerable if the password is ever divulged. Some have resorted to writing passwords on sticky notes and pasted to the computer monitor (you know who you are) which is never a good idea. Well, there is a better way. There is a small program that can keep your account passwords secure and organized. It is called KeePass and can be downloaded at https://keepass.info/. Click the Download link on the left side, then click the large green button for your operating system. Once it's downloaded, double-click to begin the installation. It's a very simple application so it's fairly intuitive.

Once KeePass is installed you now have a secure location to store all of your passwords that can be easily retrieved when necessary. One thing I would recommend doing is backing up the file that contains your passwords. You can either store it on an external flash drive or transfer to cloud storage periodically.

Hopefully this will help you manage your passwords better in 2018 and beyond. As always, if you need assistance you can reach me via my website - www.georgephillipscomputerservices.com.

Windows Update Woes - Checking for Updates (forever)

Windows Update has been problematic at times for Win7 (and Vista and 8/8.1) for many months.
This is a solution I found that has worked for me several times and for many others at another forum who had the same issue.

Solution:
  1. Download and save, but do not run yet, the standalone installers for KB3020369 and KB3172605 for your architecture (32-bit or 64-bit).
  2. Disconnect from the internet.
  3. Disable the Windows Update service in both the applet itself ("never check for updates") AND from services.msc (change it to "MANUAL" and STOP the service, then click "OK").
  4. REBOOT
  5. Run 3020369 and reboot.
  6. Run 3172605 and reboot.
  7. Go into services.msc and change WU back to "Automatic-delayed start" and start the service.
  8. Reconnect to internet.
  9. Change WU to "Install Automatically".
  10. Run a manual check for updates.
If Windows Update is partially or fully enabled when you try this, you will probably get stuck "checking for updates". WU must be disabled first.

If that process does not work and/or you get error messages with a specific error code, then you probably have a different problem.

Dell Latitude E6510 Intel Centrino Advanced-N 6200 AGN intermittently disconnects from wifi

I ran across a problem with this model laptop not connecting to our corporate wireless network or it would connect but disconnect intermittently. The laptop would, however, connect to our guest network which had no security. In a nutshell, the wifi driver for this adapter needs to be updated. Microsoft Update and the online checks indicate that the laptop has the latest version which was v13xxx. By visiting the Intel site directly at http://www.intel.com/support/detect.htm an updated wifi driver is needed and can be installed (v15xxx). After this upgrade the wifi connection works as expected.

Re-purpose Older Smart Phones

Have you ever wondered what you can do with your old smart phone after you upgrade to the newest model? You can turn it back into the store for a small credit (about $30) or sell it or leave it in a drawer OR you can turn it into a fully functional wifi device with text and call capabilities for FREE (well, except for the voip plan but it's very cheap) for your tween/teen who is itching for a smart phone but you don't want to pay for a data plan. Below are a few basic steps to get you on your way...at least with an Android device. iPhones aren't worth my time. :)

  • Upgrade your existing smart phone and transfer everything you need from the old one such as pictures and contacts. Move over your SD card, if necessary.
  • Restore your old phone to factory defaults so everything is erased and put back to good working order.
  • Go through the boot process and setup a Google account as well.
  • Install and configure Pinger for free texting. You'll also be issued a phone number so others can text you. Calling may be possible through Pinger as well but I prefer the app below.
  • Purchase a few dollars ($10 is plenty) of VoIP Phone time from a provider online. I used www.voipvoip.com. It costs less than 2 cent per minute and can be shared among multiple devices.
  • Install and configure Sipdroid for calling. Voipvoip.com has turorials to configure your specific device with their service.
That's really all you need to do to give your tween/teen a fully functional smart phone with phone and text capabilities. They can use all the apps such as Netflix, Angry Birds, Facebook, etc. as usual. The only catch is they have to be around a wifi connection. Since wifi is so prevalent these days it's a small trade-off and worth the savings of not buying a $60+/month data plan per person.

When your tween/teen is traveling with camp or sports sometimes it's important for them to be able to text or call when away from wifi. In that case, we have just added a basic phone to our plan for $10 per month without the data plan that they can share. Whichever one needs that capability takes that phone with them on the trip. It may be a little inconvenient at times but most of the time they're happy with their wifi smart phones and we're happy not having to pay for two additional data plans each month.

If anyone has other ideas to share on this topic I'd love to hear them. If someone can provide information from the iPhone world that would be helpful, too.
