Routine Maintenance

Routine maintenance is crucial to a healthy PC.

Keep your computer up to date, whether you use Windows, Apple, or any other operating system. There are a few advantages that ensure the safety of any and all portions of it. This includes security and better performance.

It’s vital to understand that cleaning up your computer’s disk drives on a regular basis may help you free up a lot of disk space. There are a variety of approaches you can take.

The first step is to run an automated operation that cleans up your hard drive, which is fairly easy to perform. Simply choose the drive you wish to clean, right-click it, and choose properties from the menu. You’ll find “Disk Cleanup” as an option. Click on it to begin the process.

Remember, the more apps you have installed and the more documents, photos, photographs, music, videos, and toolbars you have saved on your computer, the slower it will get over time.

Back Up Hard Drive

Backing up your hard drive should be done often. If you’re working on a large project, you may do this every day to ensure the security of your data. Backing up your data preserves crucial files in the event of a hard disk failure or a system disaster.

A failing hard drive is one of the worst things that may happen to your computer because of all of the important documents, photographs, and other items saved on it. Backing up your computer is highly recommended by both Mac and Microsoft technical support, and it will significantly reduce your stress. It’s also really simple to accomplish! We share how to do that here.

What is Access Time?

Access time is one of the most regularly reported performance characteristics for CD-ROM drives. It is overused at least as frequently as it is utilized correctly, as is the case with most popularly used performance metrics. Surprisingly, access time is frequently specified in CD-ROM drive specifications but is almost never mentioned in hard disk specifications. Quotes of the other variables that are used to make up access time are far more prevalent with hard disks. (Despite the fact that the devices access data in a comparable manner…)

The term “access time” refers to the length of time it takes from the start of a random read operation until data begins to be read from the disk. It is a composite statistic, made up of the following various metrics:

  • Speed Change Time: For CLV drives, the time for the spindle motor to change to the correct speed.
  • Seek Time: The time for the drive to move the heads to the right location on the disk.
  • Latency: The amount of time for the disk to turn so that the right information spins under the read head.

While access time is made up of the time spent on these individual processes, this does not imply that you can just put these other metrics together to get access time. The link is more complicated than this since some of these events might occur concurrently. There’s no reason why the spindle motor’s speed couldn’t be altered at the same time the heads are moved (and in fact this is done).

In general, the access time of a CD-ROM drive is determined by the drive’s rated “X” speed, which may and does vary greatly amongst drives. The earliest 1X drives had absolutely terrible access times, frequently reaching 300 ms; as drives became faster and quicker, access times reduced, and top-end drives currently have access times of less than 100 ms.

Part two coming up soon!

Reduce RAM to Improve Performance

First, let’s discuss what RAM is.

RAM, or Random Access Memory, is an essential and speedy type of short-term storage that your computer uses to store data that is presently in use.

With this, temporary storage is utilized by whatever apps are running on your computer, such as browsing or word editing. RAM gets purged when you shut down your computer. RAM varies from a hard disk drive or a solid state drive in that it continuously stores files and programs.

According to WindowsLatest, in the current edition of Windows, Microsoft Teams plays a larger role than predicted. The Teams application has been incorporated into the taskbar. This allowed users with personal accounts to initiate conversations or video conferencing calls, as well as add other users to the program.

Certain features and settings are enabled on Windows 11 by default that you might want to disable to improve the speed of the OS. If you have an unsupported device or old hardware with a low amount of RAM, you should immediately limit or disable the Microsoft Teams icon which is pinned to the taskbar of the new operating system.

While you can find out the RAM usage on Windows Task Manager, there’s another simple way. Here’s how to find out how much RAM your computer is utilizing, follow the steps below:

  1. Click Start
  2. Search for “About Your PC”
  3. Find the section “Device Specifications”

From there, you’ll see “Installed Ram” information. You can then determine if your computer needs an upgrade.

Romance Scams are a Thing

With Valentine’s Day around the corner, it’s best to be reminded to stay vigilant with e-mail scams. Because romance scams are a massive moneymaker for hackers.

According to the Federal Bureau of Investigations, or FBI, “In 2020, complaints filed with the FBI’s Internet Crime Complaint Center (IC3), showed that victims lost more than $281 million to romance scams. South Carolinians reported losses of more than $4.4 million that year. These schemes affect victims from all demographics, but elderly women are often targeted most.”

Outside of a dating website, rapid efforts to contact via email or messaging services is one of the warning signs of a hacker. These attacks often request money, or personal information in exchange for forms of affection or sympathy.

It’s suggested to report a romance scam to the IC3. if you suspect you have been a victim. You should notify the website or application from which the contact originated. If you come across any fraudulent or questionable transactions, you should also inform your banking institution.

Let’s Talk Bloatware

When it comes to computer terminology, seeing any word ending in ‘ware’ is worrisome. Malware, Ransomware, and spyware are just a few that raise red flags as they are created to sneak into unsecured software. This in turn gives hackers the ability to steal personal information such as social security numbers or bank credentials.

No one wants that. We want to feel safe and secure during our time on the web. I’m sure we can all be in agreement that our computer time, in general, should be a pleasant experience.

So let’s talk about another kind of ‘ware’, named Bloatware. What is it exactly?

So a short answer is, Bloatware is simply unnecessary, preinstalled software.

These preinstalled apps can cause issues within the operating system. You may find a reduction in battery life or a lower quality in performance. Just recently, WindowsLatest shared an announcement made by Microsoft. This statement explains how Microsoft understands some of the preinstalled apps available on Windows 10 are often useless to users.

“When you buy a new device, you expect it to be clean with fewer apps. Unfortunately, most new Windows 10 PCs are clogged with unnecessary preloaded software from Microsoft and OEMs, and even the clean install of the OS includes unwanted apps, such as 3D Viewer and Paint 3D.”

Thankfully, Microsoft has shared that their upcoming updates will include an ‘optional’ button for those apps you may not use. This change will most likely be seen in the upcoming Sun Valley update in October or November.

FBI Cautions About LockBit 2.0

Since its inception as a ransomware-as-a-service in September 2019, the LockBit ransomware organization has been particularly active (RaaS). After malware perpetrators were prohibited from participating on cybercrime sites, LockBit revealed the LockBit 2.0 RaaS on their data leak site two years later, in June 2021.

In a notice published on Friday, the Federal Bureau of Investigation (FBI) disclosed technical data and signs of breach linked with LockBit ransomware assaults. They stated that upon infiltrating a targeted system, LockBit 2.0 attackers increase access using publicly available tools like Mimikatz.

How To Remedy

On the FBI website, they state to lessen the danger of LockBit 2.0 ransomware penetration, the FBI advises users to utilize these preventive measures:

  • Require all accounts with password logins (e.g., service account, admin accounts, and domain admin accounts) to have strong, unique passwords. Passwords should not be reused across multiple accounts or stored on the system where an adversary may have access. Note: Devices with local administrative accounts should implement a password policy that requires strong, unique passwords for each individual administrative account.
  •  Require multi-factor authentication for all services to the extent possible, particularly for webmail, virtual private networks, and accounts that access critical systems.
  •  Keep all operating systems and software up to date. Prioritize patching knownexploited vulnerabilities. Timely patching is one of the most efficient and cost-effectivesteps an organization can take to minimize its exposure to cybersecurity threats.
  •  Remove unnecessary access to administrative shares, especially ADMIN$ and C$. IfADMIN$ and C$ are deemed operationally necessary, restrict privileges to only the necessary service or user accounts and perform continuous monitoring for anomalous activity.
  •  Use a host-based firewall to only allow connections to administrative shares via server message block (SMB) from a limited set of administrator machines.
  •  Enable protected files in the Windows Operating System to prevent unauthorized changes to critical files.Adversaries use system and network discovery techniques for network and system visibility and mapping. To limit an adversary from learning the organization’s enterprise environment, limit common system and network discovery techniques by taking the following actions:
  •  Segment networks to prevent the spread of ransomware. Network segmentation can help prevent the spread of ransomware by controlling traffic flows between—and access to—various subnetworks and by restricting adversary lateral movement.
  •  Identify, detect, and investigate abnormal activity and potential traversal of the indicated ransomware with a networking monitoring tool. To aid in detecting the ransomware, implement a tool that logs and reports all network traffic, including lateral movement activity on a network. Endpoint detection and response (EDR) tools are particularly useful for detecting lateral connections as they have insight into common and uncommon network connections for each host.
  •  Implement time-based access for accounts set at the admin level and higher. For example, the Just-in-Time (JIT) access method provisions privileged access when needed and can support enforcement of the principle of least privilege (as well as the Zero Trust model). This is a process where a network-wide policy is set in place to automatically disable admin accounts at the AD level when the account is not in direct need. When the account is needed, individual users submit their requests through an automated process that enables access to a system, but only for a set timeframe to support task completion.
  •  Disable command-line and scripting activities and permissions. Privilege escalation and lateral movement often depend on software utilities that run from the command line. If threat actors are not able to run these tools, they will have difficulty escalating privileges and/or moving laterally.
  •  Maintain offline backups of data, and regularly maintain backup and restoration. This practice will ensure the organization will not be severely interrupted, have irretrievable data.
  •  Ensure all backup data is encrypted, immutable (i.e., cannot be altered or deleted) and covers the entire organization’s data infrastructure.

Using iPad as Second Monitor

Apple’s operating system incorporates a number of handy attributes throughout all of their devices. One in particular allows iPads to be used as a second monitor.

Named Sidecar, this feature has the ability to either act as a second monitor or a mirror. Be certain both your iPad and your Mac are on the same WIFI.

“If you’re using macOS Catalina, click the AirPlay icon  in the menu bar, then choose your iPad from the menu. (If you don’t see the AirPlay icon, choose Apple menu  > System Preferences, click Displays, and select “Show mirroring options in the menu bar when available”.)”
