Adware is software that is installed onto your computer with or without your permission depending on how the adware software was installed on your computer. The main purpose for adware is to track your internet activity and drive targeted advertisements to you.
Adware that was installed “with” your permission is usually installed with another software that you choose to install. It’s usually freeware and shareware software that can include adware. Computer users who have permission-based adware installed on their pc have legally opted into this. This is usually disclosed in the fine print of an end user license agreement that you must accept in order to download specific software applications.
Adware that was installed on your pc without your permission are called malware. Malware use trickery to get the software installed on your computer. An example of malware infestation is when a website appears on the user’s screen telling the user that their computer has a virus when in reality they don’t have a virus. The website then tricks the unknowing user into installing their “antivirus” software that they never needed.
Once this type of malware is installed it is usually very difficult to remove from the user’s computer. It will take a malware removal tool to remove it. In some cases no removal tool can remove the malware and the computer has to be reformatted and the operating system has to be re-installed.
Malware and even permission-based adware can be harmful to your computer by slowing it done and or causing errors with your software. The best way to protect your computer from adware and malware is to read the entire end user license agreements before downloading any freeware or shareware software and install a well-known malware removal tool.
Computer Hardware Problem – Top 3 Warning Signs of Hard Disk Failure
Computer hardware problems can range from being harmless to catastrophic. A hard disk failure is one of the most serious hardware problems. It’s something that cannot be taken lightly because the data on the disk could be lost forever depending on the severity of the damage. Hard disk failure can occur instantly without notice and other times it can happen over time. Usually there are warning signs when a hard disk is failing over time.
I’m going to show you some warnings signs that your hard disk may be on its way out. It’s always good practice to back up your data to secondary storage before your hard disk crashes.
Warning Sign #1: Clicking or tapping noise coming from the hard drive
A computer hardware problem is imminent if you start hearing a clicking or tapping noise coming from your hard drive especially when first turning on your pc or retrieving a file. This is a really bad sign that your hard drive is dying. When you hear such unusual noises you should immediately back up your data.
Warning Sign #2: Computer is running unusually slow
Hard disk failure is a possibility if your computer is running slow and the slowness cannot be resolved through general maintenance tasks. If you already tried the following: scanned for viruses, remove temporary files and unused programs, check for software problems, defragment your disk and your computer is still slow it’s possible that the hard drive is failing.
Warning Sign #3: Files mysteriously disappeared
If you are missing some files that you know for sure the files were there and nobody deleted them, it’s possible that your disk may have some bad sectors. Your missing files may be sitting on the bad sectors. When your disk has bad sectors this is a sure sign of malfunction.
What Are Warning Signs of Hard Drive Failure?
While you may be able to repair software errors caused by bad sectors and in some cases you may be able to repair the bad sectors themselves, if your drive has begun to fail mechanically nothing will stop the process.
The key is to detect the imminent failure of your drives before they give out on you and data is lost. Let's look at some common warning signs of impending hard drive failure:
- Frequent but irregular crashes, especially while booting up Windows®
- Frequent and cryptic error messages while performing typical activities like moving files
- Folder and file names that have been scrambled and changed
- Disappearing files and folders
- Really long wait times to access folders and files
- Hard disk is silent for a long period after you request data by opening a file or folder
- Garbled output from open files or printing
- Hard drive grinds away constantly because of noisy bearings
Sound can be an excellent indicator of disk trouble! If you previously didn't hear a peep from your hard drive, but now you do... Check it. If it seems much louder than usual or makes occasional clicks or grinding sounds, check it ASAP and be prepared to backup your data and replace the drive.
If your drive is making regular clicking or grinding sounds, chances are you have a mechanical failure within the drive. Turn off your computer as soon as possible as continued use may damage the platters (data storage area) and make your data unrecoverable. The longer the drive is powered on, the more damage you may be doing to your data.
