What Does CCleaner Do, and Should You Use It?

These days, it seems like every Windows user has heard about CCleaner. It’s widely recommended, online and offline—but this week, it acted as a piggyback for malware. The real question we should be asking is: do you really need CCleaner in the first place?

CCleaner Is Disk Cleanup On Steroids

CCleaner has two main uses. One, it scans for and deletes useless files, freeing up space. Two, it erases private data like your browsing history and list of most recently opened files in various programs.

In a way, it’s kind of like Windows’ built-in Disk Cleanup tool, which frees up space on your hard drive by deleting useless files—old temporary files created by programs, temporary Internet files for Internet Explorer, Windows error report logs, and more. You can run this tool at any time to free up disk space.

CCleaner does do these things and more. It takes the Disk Cleanup concept and runs with it, extending it to more data in Windows and third-party programs that the Windows Disk Cleanup tool won’t touch. For example, it will erase cache files for other browsers like Chrome and Firefox, or delete the useless setup folders NVIDIA’s graphics driver installers create when you update your graphics drivers, which can consume hundreds of megabytes each.

Just select the types of data you want to delete, click the Analyze button, and look over the data CCleaner will delete. If you’re happy, click the Run Cleaner button to actually delete the selected files. CCleaner will remember your choices for next time, so you can just open it and click the Run Cleaner button in the future.

How to Improve the Appearance of Fonts

By default, Microsoft Windows Vista and 7 have ClearType enabled. However, if you want to customize the text even more, you can run the ClearType Text Tuner by following the steps below.

  1. Click Start or press the Windows key on the keyboard.
  2. In the search and run box type cttune.exe and press Enter.
  3. This action opens the Windows ClearType Text Tuner program, which should resemble the example picture below. This program allows you to improve the quality of how text looks on your screen.

What Is AMD

AMD may refer to any of the following:

Short for Advanced Micro Devices, AMD is a computer company best known for its computer processors. See our AMD corporate information listing for complete company details.

AMD is short for asynchronous method dispatch.

AMD is the second largest maker of personal computer microprocessors after Intel. They also make flash memory, integrated circuits for networking devices, and programmable logic devices. AMD reports that it has sold over 100 million x86 (Windows-compatible) microprocessors. Its Athlon (formerly called the “K7”) microprocessor, delivered in mid-1999, was the the first to support a 200 MHz bus. In March, 2000, AMD announced the first 1 gigahertz PC microprocessor in a new version of the Athlon.

Founded in 1969, AMD along with Cyrix has often offered computer manufacturers a lower-cost alternative to the microprocessors from Intel. AMD develops and manufactures its processors and other products in facilities in Sunnyvale, California, and Austin,Texas. A new fabrication facility was opened in Dresden, Germany, in 1999.

The lower cost of AMD’s microprocessors was a contributor to lower PC prices in the 1998-2000 period. Reviewers generally rated the K6 and Athlon equivalent to or slightly better than comparable Pentium microprocessors from Intel. In addition to “the first mainstream 200 MHz system bus,” Athlon includes a superscalar pipelining floating point unit, and a programmable L1 and L2. The Athlon uses AMD’s aluminum 0.18 micron technology.

What is Malwarebytes?

The free version of Malwarebytes is an advertisement for the paid one.

And that was a single way for them to enter the Antimalware market (and, later, Antivirus) when it is saturated, with a sub-par program and relatively little investment.

It was quite good for removing specific threats for computer repair people and also it brought some commission if the customer later bought it. And there were huge initiatives to buy one: the first version of MBAM had a lifetime subscription.

What is Remote tool TEAMVIEWER

TeamViewer is one of the most popular remote support tools in the world. It allows you to access and control a computer from anywhere in the world. This program is also very easy to setup and use. All you need to do is install the program on both devices — no additional steps for setup are needed.
TeamViewer can be used with nearly any type of device, including smartphones.

Is it better to leave the computer on or turn it off?

Even though sessions vary with usage, everyone needs to step away from their computers at some point. Many of our users wonder if it’s a good idea to leave their computers on, or turn them off. The answer to this question depends on many factors ranging from electricity bills to concerns about wear and tear. The following sections address the “on or off” debate from many viewpoints, allowing you to decide what works best for you.

Power concerns
Associated costs:
One of the biggest contributing factors when deciding whether or not to turn off your machine is the electrical cost. A bill for electricity can be expensive, and a computer like many household electronic devices adds to the cost. Unless you’ll be away for a very long time from a computer that’s on, the difference in price isn’t a large concern. However, if you’re looking to save a few dollars a month, shut it down.

Time to resume
In our opinion, the time for your computer to resume working is a bigger factor than the cost of electricity. For instance, if you open and close your laptop frequently, you don’t want to have to reboot it completely each time. Knowing a bit about the different power states of a computer should help you in your decision.

Sleep – All open applications and files are stored in RAM, and the rest of the computer components are put into a low-power state. This option is best when you step away from your computer for a short time because it allows work to be resumed almost immediately.
Hibernate – With hibernate mode, all open applications and files are copied onto your computer’s boot drive, and the rest of the computer is essentially shut down. This option is good if you’ll be away from your computer for a short time.
Shut down – When you shut a computer down, all files and applications are closed, and power to the computer’s internal components is cut off. Shutting down is a good option if you’ll be away from your computer for an extended period (e.g., more than eight hours).

Leaving your computer on overnight
Our recommendation is to turn off your computer when you go to bed, as it saves you a bit of money on your electricity bill. However, for tasks to run during the night (e.g., backup, ScanDisk, Defrag, updates, or a virus scan), you’ll need to leave your computer on while you sleep. Unless you don’t mind these tasks being performed during the day.

Will turning off a computer wear down moving parts (e.g., fans)?
No. The only moving parts that caused an issue internally were within a component, not the computer itself. In older hard drives, the head would come into contact with the disk platter upon shutdown, which caused it to wear. However, any hard drive manufactured today doesn’t have this issue.

Does turning off a computer wear down the power button?
Before 1994, it may have been beneficial to leave the computer on due to potential power switch related issues associated with certain manufacturers that caused the power buttons to break early. However, this issue was only applicable to a very small portion of old OEM computers, and today is no longer a problem. Power buttons can still wear out, but they have a life cycle that outlasts the other components of your computer.

Does turning off a computer cause soldering cracks?
No. Solder can withstand changes in temperature; turning a computer off frequently does not harm it. For example, many individuals turn their TV on and off each day, sometimes several times. Much like a computer, components inside the TV get hot and cool down, and these devices rarely have problems.

Will turning my computer off help prevent a power surge?
Power surge
No. A power surge destroys electrical devices, regardless of whether they are on or off. Having the power cord connected to a surge protector can safeguard a computer from an electrical surge.

What are the F1 through F12 keys?

The function keys or F-keys on a computer keyboard, labeled F1 through F12, are keys that have a special function defined by the operating system, or by a currently running program. They may be combined with the Alt or Ctrl keys.

On laptop computers

On some smaller keyboards and laptop computers the F-keys may have a dedicated function such as changing the screen brightness, the volume, or other device-specific functions. On these keyboards, there is a separate Fn key that you can hold down to indicate that you want to use the key as a standard function key. For instance, on the MacBook Pro laptop computer, the F12 key’s primary function is to increase the audio volume. If this key is pressed while the Fn key is held down, the key registers as F12 and trigger any software functions configured to use this key.

If you would prefer not to press the Fn key to access your function keys, you can configure the keyboard to treat them as regular function keys in your Control Panel or System Settings.

If your keyboard does not have a row of function keys, they are probably set up as secondary functions on other keys. Look for alternate labels on your keys, or consult your computer’s manual for more information.

Below are some of the more common functions of the functions keys for Windows and macOS. As mentioned above, not all programs support these function keys, and the function keys on your keyboard may perform different tasks than those mentioned below.
