How to Block Spyware

Spyware refers to software that is installed on a computer without knowledge of the user. It can be used to track and monitor computer use to send to third parties for marketing purposes. Spyware programs can be a nuisance, as they can take up computer processing capacity, collect personal information and send pop up advertisements without permission. Through key loggers or taking screen captures or scanning hard drives, spyware can maliciously take personal information for criminal gain. There are several steps you can take to block spyware from your computer.

Steps:

1. Be careful when you download. Knowing what you are downloading and from what site is an important measure when it comes to blocking spyware. Many spyware programs are downloaded unknowingly when you download other software. You should always read the End User License Agreement as sometimes spyware programs are allowed access through third party advertisements when you click to accept the software you are downloading.
   
   
2. Avoid peer-to-peer file sharing. This is another common way for spyware to enter your computer. Peer-to-peer file sharing is risky, as the content of the other person’s computer is unknown and viruses and spyware can be spread this way. The best way to block spyware is to prevent possibilities for it to get on your computer.
3. Use add-ons on your Internet browser. Internet browsers such as Firefox, Opera or Internet Explorer have add-ons that block pop up ads from appearing while you surf. This is also another important measure in preventing spyware, as clicking on pop up ads can inadvertently lead to spyware downloads on your computer.
4. Install anti-spyware software.
   • Read reviews on anti-spyware software. Descriptions and user reviews are posted on many consumer reviews sites. One of the things you will want to consider in your search for an anti-spyware software is the scanning speed, which is how quickly it can scan through your entire hard drive to detect spyware and viruses. You will want to compare accuracy, which is the software’s ability to filter out legitimate programs versus actual spyware sites or programs. You will also want to know how frequently the software updates their software when there are known new spyware and virus attacks and consider the technical support offered with your anti-spyware software.
   • Find freeware or shareware. There are a number of freeware and shareware sites that offer free anti-spyware. These will be more limited than commercial software programs, but can provide you with adequate protection from spyware. Make sure that the site that you downloading from is reputable.
   • Buy commercial software. Alternatively, you can buy commercial anti-spyware software. Most commercial anti-spyware software is bundled with anti-virus software programs.
   • Check for updates frequently. Even with anti-spyware software installed on your computer, you will want to check periodically for updates from the software manufacturer as new spyware and adware viruses are developed. These updates will protect you from the latest spyware programs.
5. Keep your operating system up to date. Keeping your computer’s operating system up-to-date is important in preventing spyware or viruses from your computer. Operating system security patches are released often from the manufacturers that can fix holes in your system that hackers and spyware can break through. Make sure that your operating system is the latest version released from the manufacturer. Most operating systems will automatically check for updates periodically.
6. Control which memory devices can connect to a workstation. Block USB Memory Sticks, eSATA Drives, USB 3.0, DVD or CD Write. Any Memory storage device.
