Roblox is a very popular online game with millions of gamers playing it each day and as such it will naturally bring a lot of malware and attack on players trying to steal and exploit them for monetary gains. The latest attack and high-profile stealing of currency and assets happened exactly in Roblox.

Malicious activities have been reported to come from chrome extensions. So far 2 extensions have been identified that have hidden malware inside them but there could be more of them currently undetected. Extensions work as a front while in the back they mine user logins and other data in order to steal stuff from the Roblox platform.

To make things worse some of the malware is within long extensions like SearchBlox. The SearchBlox extension allows you to search quickly for other users if it was legitimate but has been compromised within the last month. There is evidence that people are stealing Roblox currency with the data gathered by the hidden backdoor in it.

SearchBlox extension is still Active in Chrome Web Store, with the primary listing still with the "Featured " badge. Google is actively removing malicious software from its storefront on a regular basis but this one still lingers in it.

If you or your kid have this Chrome extension installed, uninstall it right away and always be careful about which extension you install and give access to your system, keep them updated and check various blogs and article sites to inform yourself when a bad one is found.

If you encounter an error while trying to burn files to a CD or disk on your Windows 10 computer, stating, “Windows Media Player cannot burn some of the files”, read on as this post will guide you in fixing the error. Here’s the complete error message:

“Windows Media Player cannot burn some of the files. To investigate the problem, click the icon next to the files in the burn list.”

As you know, the Windows Media Player helps you burn songs or audio files to CD or disk but it does not always end up successfully as you could encounter some setbacks such as this particular error. Usually, this kind of issue occurs if an audio file does not comply with some restrictions so the Windows Media Player pops up this error instead. You can encounter this error message if:

• You include a file that’s not an audio file.
• If the total time limit exceeds 80 minutes (even though a CD has 700 MB storage capacity, you can’t burn audio of more than 80 minutes long)

To resolve the error, you have to remove the unsupported files from the burning list, change the burning speed or execute some tweaks in the Privacy settings. For more details, refer to the instructions provided below.

Option 1 – Get rid of the unsupported files from the burning list

You must get rid of the unsupported files from the list of files to burn. This list can be found on the right-hand side of the Windows Media Player. One of the indications that a file is causing problems is when there is a white cross in a red circle next to the file. You can simply click on that icon to remove the file from the burning list. Once you’ve gotten rid of all the unsupported files, try to burn your files to the CD or disk once more.

Option 2 – Try to modify the Privacy settings

In case you don’t know, the Windows Media Player comes with privacy settings that help you in various situations. However, on rare occasions, those settings could also trigger errors and this might be the one that’s causing the “Windows Media Player cannot burn some of the files” to pop up. Thus, you can try disabling these options to resolve the error. How? Refer to these steps:

• Open the Windows Media Player.
• Then go to Tools > Options. If you aren’t able to find the Tools menu, just tap the Ctrl + M keys. On the other hand, you can also tap the Alt key to display the menu options.
• Once you’ve opened the Options window, go to the Privacy tab where you can the “Enhanced Playback and Device Experience” section.
• In this section, you can find the following options. Make sure to disable them all.
  • Display media information from the Internet
  • Update music files by retrieving media info from the Internet
  • Download usage rights automatically when I play or sync a file
  • Automatically check if protected files need to be refreshed
  • Set clock on devices automatically

• After you disable the options listed above, click on the Apply and OK buttons to save the changes made and then try to burn the files again.

Option 3 – Try to change the burning speed

Since the burning speed is set to fastest by default, you can try to change the burning speed to resolve the problem. All you have to do is open the Options window and then go to the Burn tab. From there, select either Medium or Slow burning speed and save the changes made. Now try to burn your files to the CD or disk once again.

One of the most sophisticated Artificial Intelligence or AI assistants there is in the market is Cortana. However, no matter how sophisticated this AI assistant may be, there are still times when you encounter issues with it. So if your Cortana is not connecting to the internet, worry not for this post will guide you in fixing the problem. This connection issue in Cortana might have something to do with the settings, network connectivity, or your Microsoft account.

After that, check if you have a Verify hyperlink under your Microsoft account or not then click on Verify. Afterward, follow the next on-screen prompts to verify your Microsoft account. Once your account is verified, restart your computer.

Option 7 – Try resetting Cortana

• Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
• Restart your PC.
• After your computer boots, launch Cortana again and check.

Option 8 – Try to reinstall Cortana

If none of the options given above works, you must consider reinstalling Cortana.

• First, right-click on the Start button and click on the Windows Powershell (Admin) option from the list.
• Next, type the following command and hit Enter to execute it:

Get-AppXPackage -Name Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

If you were trying to install a program on your Windows 10 computer but encounter an error instead that says, “Error 1310, Error writing to file: <PATH>, Verify that you have access to that directory” then read on as this post will guide you on how you can fix it. This kind is a fairly common type of error encountered by many Windows users. You can get this error when you try to install certain programs like Excel, AutoCAD, Adobe Photoshop, and some other Adobe products on Windows. One of the most likely causes for this error is that the required files or location is already used by some other software which means that Windows finds that you are trying to overwrite a software that is already installed. Aside from that, it could also occur if the program installer does not have access to write to that directory. To fix Error 1310, here are some potential fixes that could help.

Option 1 – Clear up temporary or junk files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Option 2 – Reinstall the program in a Clean Boot State

You can also troubleshoot Error 1310 in a Clean Boot state. It could be that there are some third-party applications in your computer that's preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 3 – Try to unregister and re-register the Windows Installer Module

• Tap the Win + R keys to open the Run dialog box.
• Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
• Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
• Now restart your computer and see if un-registering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Take ownership of the location where you want to install the app

The next thing you can try to do is to take ownership of the particular folder as this worked for some users who experienced the same problem. But before you do that, you have to create a System Restore Point first, once that’s done, proceed to the given steps below.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.
• Finally, try to install the application again.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.
