Ten Computer Repair Myths

Facts Over Myths Myrtle Beach

If you’re like most of us, it’s hard to know what’s fact and what’s fiction when it comes to computer repair. We thought we’d take some common myths and shed some light on what you really need to know.

  1. Slow computers need to be reformatted. This is perhaps one of the most common myths out there. Just because you have a computer that is running too slow doesn’t mean you need to reinstall Windows! Slow computers can be caused by many things, including lack of hard drive space, malware and viruses or just having too much stuff on it. Unused software takes up a lot of space and can bog down your machine. We don’t reformat computers in our shop unless it’s a last resort!
  1. My computer is running slow so I need to buy a new one. We would never tell you not to buy a new computer if you want one, but you don’t have to do that just because your current one is running a bit slowly. Computers don’t run slow simply because they are puckering out. There’s usually a reason that is very fixable. Allow a professional computer repair company to look at your old computer before jumping into the decision to spend money on a new one. You might be surprised what can be done!
  2. If I have a Mac, I won’t get a virus. Let’s be clear—Macs are NOT immune to viruses. It’s true that in the early days of Mac, viruses weren’t able to handle their operating system. However, Mac’s OSX and iOS now are more vulnerable as cyber hackers have come up with viruses that can, indeed, infect Mac computers.
  3. Windows Firewall is all you need to stay safe. We wish this were true, but alas, it’s not so. Windows firewall is excellent and goes a long way to protect your computer, but it isn’t enough. To avoid problems, it’s imperative that you also have a good antivirus software and malware protection.
  4. Windows Defender is built into Windows, so it’s always the best. We hear this one a lot and felt the need to shed some light on this myth. While Windows Defender is good, there are still other third-party antivirus software programs that are superior. To get the absolute best antivirus protection, talk to Tech Sentries! We’ve got your back.
  5. You need new memory to keep your computer from continuing to crash. This is outrageous to assume that faulty RAM is the only reason your computer crashes. There are many things we look for, including updates gone wrong, Windows errors, conflicts with software and several other issues that a good computer repair shop will know to check for.
  6. Name brand parts always last longer and work better. This can be true of many things, for sure. However, when it comes to computer parts, the main difference is the quality control and tech support offered by branded parts. Often, the parts are made under the same roof as the generic parts and have the same standards of production. Branded parts do not always work better or longer.
  7. You should always drain the battery in your laptop to get the longest charge. While this may have been true in the early days of laptops, it is no longer the case. Older batteries were made of Nickel-Metal-Hydride and it was thought that draining the battery was necessary to keep your battery working longer. Today’s laptop batteries are made from lithium ion and work the opposite. Draining your lithium battery before charging will actually cause it to resist charging over time. The answer here is to charge your battery whenever you feel like it, no matter how drained it is.
  8. Wipe your hard drive clean with a magnet before you sell them. Here’s the truth—it doesn’t work. It worked back when we still used floppy disks, but this is no longer the case. The only way to securely wipe your hard drive clean is by employing specific software that overwrites several times over each memory sector.
  9. You’re completely safe online as long as you’re in private or incognito mode. This is a big one and it’s completely untrue. Private mode will prevent you being tracked on your own computer, but it will not prevent you from outside tracking or from hackers, viruses or malware. Private mode does prevent the browser you are using from using any cookies or creating data from your searches. If you are on a network computer at work, your employer may still be able to track your online searches, so it’s important that you stay safe and avoid any websites that could cause problems for you, whether you are in private mode or not.

Computer Encryption and How it Works

computer encryption Myrtle BeachKeeping others from being able to see the content on your computer is your right. No justification is needed—only appropriate action. In today’s political climate, computer security is one of the most common questions we are asked here at Tech Sentries. These questions often deal with protecting your data, keeping the government out of your affairs, and even encryption. If you don’t know what encryption means, much less how it’s used, this article is for you!

So Just What Does Computer Encryption Mean?

Basically, encryption involves scrambling text into a unique code using mathematics. Special encryption software uses algorithms to generate these codes from your text. Unless you are a person who knows how to unlock this code, it will look like unrecognizable nonsense.

The key to unlock encryption is referred to as a cipher. They have been used in many ways for the last 2000 years. Due to their complexity, it can take many years for any person or computer to successfully decode or unlock the cipher.

The truth is we all use computer encryption everyday but might not be aware of it. Did you know that each time you log into your bank account, join a Wi-Fi network or shop on an HTTPS site you are using encryption? These types of transactions use encryption called “in transit,” which deals with information transferred over the internet. If a file or disk gets encrypted on a computer, it’s referred to as “in place or at rest” encryption.

To put it simply, think of encryption as bits. The standard encryption key uses 256 bits, which literally has billions of possible cipher combos. The math is downright overwhelming! The two most common encryption types are symmetrical and asymmetrical. This simply means that with symmetrical, the same key is used to both lock and unlock the encrypted files. The opposite is true of asymmetrical—one key locks it and another unlocks it. The latter is the more commonly used method.

How Does Computer Encryption Work?

Certain software is used that creates ciphers which are highly complicated. This is what will scramble the data in your folders and files. Often, the encryption is so complicated that it can only be read once unless properly decrypted or “unlocked.” While a supercomputer or superhuman might be able to decode the encryption, it would likely take many years. Instead, encryption software can be installed like other programs and you will need a strong password to protect the files it encrypts. The password is your cipher to unlock everything so it is crucial to choose wisely when creating this password. Here are some tips:

  1. Don’t use words from the dictionary
  2. Try creating a phrase rather than just a word
  3. The more characters, the stronger the password
  4. If possible, use combinations of upper and lowercase letters, numbers and special characters such as (#$%&!).

You might have a file with one or more lines of text in it that could be dangerous. If you enter that line into your encryption software, it would take the line of text and convert it to a long combination of letters, numbers and characters that would make no sense to anyone unless decoded. It may end up looking far longer than your original line of text, which makes it even harder for a hacker to get to it.

Should I Encrypt My Data?

For the most part, we strongly encourage everyone to encrypt their data. Even more so if you use tablets and/or laptops. Encryption goes a long way in protecting you from spying eyes of thieves, hackers, and even government. It also prevents malware and other viruses from getting into your data. The simple fact that it takes your carefully chosen password to unlock your files makes encryption worth it—everyone who values their privacy and security should use it!

There are a few options depending on what device you’re using.

Each of these options works in much the same way. Enable or install the encryption program, set a drive or folder, give it a secure password and encrypt. Just do not forget that password!

What About Backdoors?

The term “backdoors” has come up when certain officials aren’t happy with security companies not providing them a “backdoor” way to access encrypted files. Government seems to always want to put more surveillance in place and they don’t take too kindly to companies refusing to provide them with a hidden key that would allow them access to the data they want whenever they choose. Fortunately, no backdoor access is currently being enforced and we have no reason to believe that these security companies are building any backdoor access to their encrypted data files.

The bottom line is encrypting your files is legal, free and easy to do. If you run a business or just have personal files you don’t ever want anyone gaining access to, computer encryption is the safest thing to do!
