Memory for an HP G70-460US laptop

An HP laptop running the Microsoft Windows 10 operating system that I was using was performing poorly and when I checked the system's performance with the Windows Task Manager, I could see that the memory utilization was consistently high. So I decided to check on whether I could increase the memory in the system. A sticker on the underside of the laptop showed the model number to be G70-460US. I wondered whether I could also get the model number from a Windows Management Instrumentation Command-line (WMIC) command if the sticker was no longer present or was illegible, so I opened a command prompt window and checked to see what information I could get using the wmic csproduct get command.

Windows Defender detected TrojanClicker:JS/Chroject.A

I recently removed Trojan:Win32/Nymaim, which was detected by Windows Defender on a Microsoft Windows 10 system. When Windows Defender detected that malware, it prevented the weekly backup program on the system, which was the Windows 7 backup and restore utility, from completing successfully. After removing that malware, I ran the backup program again, but I found that again the backup program did not complete successfully due to Windows detecting a trojan during the backup operation. This time it was TrojanClicker:JS/Chroject.A.

Windows Defender detected Trojan:Win32/Nymaim

When I checked a Windows 10 system to ensure that the Windows 7 backup program that is scheduled to perform weekly backups of the system was functioning properly, I found that the last successful backup occurred on November 11, 2018. When I clicked on "More information" to determine the cause of the weekly backups failing, I saw the message "Operation did not complete successfully because the file contains a virus or potentially unwanted software." So I opened the Windows Security application by clicking on the Windows Start button, then selecting Settings, then Update & Security, then Windows Security. I then clicked on Virus & threat protection and selected Protection history, which showed an entry of "Remediation incomplete" for the backup that ran on February 16, 2020. The issue encountered was listed as "servere." I clicked on the downward-pointing arrowhead next to "severe" which showed the following for the malware detected:

Threat detected:Trojan:Win32/Nymaim
Alert level:Severe
Date:2/16/2020 10:46 PM
Category:Trojan
Details:This program is dangerous and executes commands from an attacker.

Windows 7 Backup Failed Due to Detection of Virus in Shadow Copy

Microsoft Windows 10 comes with a backup program that will allow you to create a system image for backups. You can get to it by right-clicking on the Windows Start button and choosing "Settings" then "Backup," which is under "Update & Security," and then selecting "Go to Backup and Restore (Windows 7)." That program was being used to backup a Windows 10 system every weekend, but when I checked the status of backups for the system, I saw a message stating "The last backup did not complete successfully." I clicked on the "More information" button and saw a "Check your backup" message stating that the "Operation did not complete successfully because the file contains a virus or potentially unwanted software." When I clicked on "Show Details," I saw the time of the failed backup and "Error code: 0x800700E1."

Determining the time a registry key was last updated

When I ran a scan of a Windows System with Spybot Search & Destroy 1.62, it reported it found a Windows registry key associated with GhostMail - it identified GhostMail as adware. To check the registry key, I typed regedit in the "Type here to search" field at the bottom of the screen and then selected the "Registry Editor" app when it appeared in the list of returned results (you can also open the application by typing regedit and hitting enter at a command prompt. I then navigated to the relevant key. I wanted to determine when the registry was created or at least when it was last modified. You can't see that information in the Windows Registry Editor, but you can create a text file that will contain that information by right-clicking on a key and choosing "Export" to generate a text file - select "Text Files (*.txt)" in the "Save as type" field, not the default value of "Registration Files (*.reg)." The text file will contain the key as well as the time it was last written to:

Key Name:HKEY_USERS\S-1-5-21-3084690208-3888753220-1328190817-1115\Software\Albert Yale
Class Name:<NO CLASS>
Last Write Time:8/16/2019 - 10:54 PM

In this case, the date on the key was months ago, so didn't explain recent problems on the user's PC and since Spybot - Search & Destroy didn't locate anything else, the registry key may have been a remnant of something removed many months ago.

Memory for a Dell Inspiron 570 PC

A user reported her Windows 10 system was running slowly. When I connected to the system remotely to check it after the user had left for the day and closed all the applications she had running, I found that the memory utilization was 78%. I knew the system was a Dell PC, but I didn't remember the model number. I was able to determine it was an Inspiron 570 by right-clicking on the Windows Start button and choosing System. Under "Device specifications," I saw "Inspiron 570". I also saw that the system had only 3 GB of memory installed.

Inspiron 570
Processor: AMD Athlon(tm) II X2 240 Processor 2.80 GHz
Installed RAM: 3.00 GB (2.75 GB usable)

Minecraft libraries failed to download

When I tried to install Minecraft on a Microsoft Windows system using the Windows Installer file I had downloaded, I saw the error message "These libraries failed to download. Try again. org.ow2.asm:asm-all:5.2."

Libraries failed to download

I then clicked on the link for "Installer" rather than "Windows Installer on the website from which I had downloaded the installation file, which resulted in a .jar file being downloaded. I right-clicked on the .jar file, forge-1.12.2-14.23.5.2768-installer.jar, and chose "Open with" then "Java(TM) Platform SE binary". I was then able to install the Minecraft client. When the client was successfully installed, I saw the message "Successfully installed client profile forger for version forge 1.12.2-14.23.5.2768 into launcher and grabbed 1 required libraries."

Successfully installed client profile forge

Note: These are notes from an October 12, 2019 installation that I hadn't posted, but I am posting now in case I encounter a similar error again.

Comparing Excel workbooks in Microsoft Excel for Mac

I needed to compare two Excel workbooks produced with Microsoft Excel for Mac (version 16.29) on my MacBook Pro laptop. Unfortunately, the MAC version of Excel doesn't include a capability to directly compare two workbooks. Since both workbooks only had one worksheet in them, I created a new workbook and then copied the contents of the worksheet in the first workbook to Sheet1 in the new workbook and the contents of the worksheet in the second workbook to Sheet2 in the new workbook. I copied the contents of the worksheets by selecting Edit and then Select All in a worksheet and then pasting the contents into a sheet in the new workbook. I then created a third worksheet, Sheet3 in the new workbook. In cell A1 in that workbook, I put the formula =IF(Sheet1!A1 <> Sheet2!A1, "Sheet1:"&Sheet1!A1&" vs Sheet2:"&Sheet2!A1, ""). I clicked in that cell and then clicked on Edit and then Copy. Since the columns in both of the worksheets I wanted to compare extended to AE with 804 rows, I then selected all of the columns from A to AE and all rows from 1 to 804 and then clicked on Edit and then Paste Special with All selected. I then clicked on OK to copy the formula throughout the new worksheet. Excel automatically updates the references so that B2, for instance, gets the formula =IF(Sheet1!B2 <> Sheet2!B2, "Sheet1:"&Sheet1!B2&" vs Sheet2:"&Sheet2!B2, "").

Excel then showed the differences between Sheet1 and Sheet2 in Sheet3 where I had used a formula to compare cells in the two other sheets. If the contents of a cell differed, Excel showed the differences. E.g. for cell A71, I saw Sheet1:I13-0003 vs Sheet2:I97-0033, since Sheet1 had I13-0003 in that cell whereas Sheet2 had I97-0033 . If the cells matched, the corresponding cell in Sheet3 was empty.

So, even though the Mac version of Excel doesn't include the workbook comparison feature found in Windows versions of the program described at How to compare two Excel files for differences, you still may be able to compare sheets in two Excel files by copying relevant sheets into a new sheet where you can see the differences displayed. In the exmple above, the contents of E71 in Sheet3 showed the values for the other sheets as numeric values, though there were dates in the corresponding cells in Sheet1 and Sheet2.

Memory for a Gigabyte 970A-DS3P Motherboard

I needed to determine the amount of memory currently in a PC running the Windows 10 operating system and how much more memory could be added to the system in order to improve its performance. To determine how much memory could be added, since it was a custom-built PC, I needed to determine the motherboard in the system. I didn't want to disconnect every device attached to it and open it up, so an option is to use Windows Management Instrumentation Command-line (WMIC) commands to determine the motherboard manufacturer and model number. You can also use WMIC commands to obtain details about the memory already in a system.
