Spyware is a variety of malware. Spyware is picked up during your surfing and it attaches itself to your computer, offering information about what you do and where you go in your online activities. Spyware blockers, fortunately, can prevent that installation.

Usually the spyware is installed and stays on your computer without your knowing and logs aspects of your activity, however some spyware is actually put there on purpose by companies, in order to log the activities of employees of larger corporations.

You can pick up spyware by visiting multiple sites and some spyware is installed by companies who are advertising anti-spyware software in order to sell their products.

According to a study that AOL did in 2005, more than sixty percent of computers were infected with spyware. Of that percentage, 90% said they didn’t even know it was on their computer and most had not given permission, or even been asked by the company or site that installed it for their permission. Spyware blockers are a necessary part of your computer software, particularly if you work online or spend any amount of time visiting websites.

How Do You Combat Spyware?

Spyware blockers can help you to remove the spyware from your computer. Spyware removal will help to speed your computer back up, prevent you from being redirected to advertisements, in some cases even prevent identity theft.

The spyware remover software that can be found on this site like Spyware Doctor, is a fully functional software that can assist you in preventing infection from spyware and also remove the spyware which was previously been installed on your computer.

How Does a Spyware Remover Work

Spyware removing software such as Spyware Doctor, monitors your computer in real time. It can actually “see” when a site is attempting to serve you up spyware, or install something without your permission and prevent the installation.

The software was designed to monitor your computer and inform you when a site or software attempts to install something without your permission and to block that installation.

When you install spyware removers, on the first run of the software it will remove the known spyware that is on your computer. Much like other software is updated on a regular basis, so too is spyware. As spyware removers become more intelligent, spyware is fixed to circumvent it.

In response, spyware removers become more sophisticated and are also updated to continuously keep your PC safe from invasive software. Keeping your spyware removers and adware blockers updated fully by setting them to auto-update, or by updating them manually on a regular basis is your best protection against having your PC infected.

Spybot also has real time protection in the form of the “Resident TeaTimer” which informs you when different processes try to start and also let’s know when something wants to change some critical registry keys giving you the option to either “allow” or “deny” the change. Pretty useful stuff.

As I said before, the user interface isn’t the most obvious and easy to use so here is a quick install and user guide. Running Spybot this way has (touch wood) kept all my PCs running smoothly for years!

1 – First things first, Download Spybot S&D and follow the on screen installation instructions.

2 – On first run, Spybot starts the wizard. I just keep clicking the next arrow until step 7 and click “start using program”.

3 – Now that you have successfully installed Spybot, the first thing you need to update the program with the latest detection and immunisation databases. Do this by clicking the “Search for Updates” and follow the onscreen instructions. Once the updates have finished, close the update window and go back to the main program.

4 – If you are already experiencing signs of spyware infection (popup ads, changing homepage, slow internet connection etc), you must perform a system scan and if prompted, do a boot scan. Doing a boot scan means Spybot can remove any spyware before they get a chance to load through the “backdoor” on your PC and block Spybot from removing them with a standard scan. It is also worth mentioning that if you have several accounts (users) on your PC, you should login to each one and scan them with Spybot as well.

Remember to press the “fix selected problems” button if Spybot finds anything!! Don’t just assume that just because Spybot has found problems, it has cleared your PC!

5 – Now Spybot has scanned and cleaned you PC, its time to immunise it. This should keep your PC spyware free by blocking any malware before it gets on to your system in the first place. The immunise function, like the update function is not automatic and will require you to manually update it weekly (well that’s what seems to works for me anyway). Below, you can see the immunise screen of Spybot. Close all browsers you might have open and click the green cross immunise button at the top. All the numbers in the red “unprotected” column will move to the green “protected” column.

That’s it. I run Spybot in conjunction with AVG free anti-virus on several PCs and touch wood, have not had any problems for several years with any spyware or viruses.

Statistics indicate that as many as 90 percent of all computer users have been infected with spyware or adware at one time. Every time you surf the Internet, watch videos, download a file, you risk corruption from spyware or adware.

The term spyware was first heard in the mid 1990s in an article targeted at Microsoft. In 2000, the term spyware was associated with a program for a personal firewall, and soon afterward became a common term. The first anti-spyware program, developed in the late 90s, was “Optout”. Created by Steve Gibson, it was his solution to preventing spyware on his computer.

A basic definition of spyware today is, “computer software that obtains information from a user’s computer without the user’s knowledge or consent.” Known also as malware, its primary purpose is to collect and transmit information for advertising purposes. Spyware is most commonly installed through shareware or freeware programs, causing significant damage to a computer. Spyware can cause re-directs to sites on the Web, change a user’s homepage, change computer settings causing slower connection speeds, and interfere with the overall functionality of the computer. Spyware can also collect information such as passwords and credit card numbers. Once integrated into the system, spyware uses valuable memory resources and bandwidth. The former can cause erratic crashes while the latter slows internet activity.

Adware is a program aimed at users who do not wish to pay for software. Often bundled with “freeware”, adware is the software developer’s answer to revenue by integrating advertisements into the software. An example would be free software you utilize in “sponsor mode” that may have an advertisement window visible each time the software is used. Adware is considered legitimate in these cases and installed with the user‘s knowledge. Normally the adware can be removed simply by paying for the software license. This type of adware is considered non-malicious. Adware that is downloaded by clicking on a pop-up advertisement, or piggybacked on some shareware/freeware can be malicious and exploit holes in your system’s security. Some adware can be downloaded simply by visiting a website on the Internet.

If you are Internet active, you need spyware and adware protection software. These programs will identify and remove threats from your system during a scan process as well as protect you in real-time. There are many programs on the market today for this purpose, such as Spyware Doctor from PC Tools. Like other anti-spyware programs, Spyware Doctor will perform complete scans of your computer to identify and remove any infections. Most spyware protection software is non-intrusive and performs all its tasks in the background, protecting the user in real-time. Programs such as Spyware Doctor are highly configurable with a wide range of options.

Adware can be removed by software specifically designed for that purpose, but may also be removed by some spyware protection programs. Spyware Doctor can detect and remove spyware and adware. Adware removal software will perform the same function as spyware protection programs, scanning your system for threats and removing or quarantining them.

To protect yourself from spyware, install spyware protection software. Make certain you update daily to avoid new threats. Perform daily or weekly scans. Most programs can be configured to perform these steps automatically. Run the software each time you use the computer for real-time protection.

Protecting yourself from adware is much the same process. Utilize a software for this purpose and run scans daily or weekly. Make certain your threat database is current. Run the software in the background to protect you. Be aware that some free software will not run when adware is removed.

Spyware is the name that is collectively given to a class of software that is installed on a computer to secretly retrieve data from a user or network. Though there are legitimate spyware programs, most are written with malicious intentions, including the harvesting of personal financial information.

The use of spyware programs, or spyware-like tactics, have been around almost as long as network system have been. Some of earliest programs made use of ‘backdoors’ that were written into server software as a maintenance feature or failsafe. These were used more to wreck havoc on systems than extract information, though.

Large corporations were amongst the first users of legitimate spyware software. Wondering exactly what each employee was actually doing while using a computer, spyware programs could be quietly installed on each terminal to monitor keystrokes and files accessed. Some spyware even measured words-per-minute typed, allowing close monitoring of data entry personnel.

Ultimately, it was the desire for more web-based functionality and interactivity that lead to the current incarnation of spyware. In order for web-based applications to maintain and provide services, new types of procedural programs needed to be written and integrated into operating systems. In order for this scheme to work, a web browser would need to be able to download and install pieces of computer code that would be run on the host system.

These objects could be made to appear as normal objects, but would actually contain programs that would harm or record data on the host system and transmit it to another site.

With broadband access, it became even easier. Now that computers were constantly connected to the internet while they were on, applications that provided internet-based services could be bundled with spyware. This meant installing and running such a seemingly benign program could infect a computer without the user ever knowing.

Once spyware is installed, it can have almost total control over the system. The trick, so far, has been getting a user to agree to install the program. Even with the ease of getting through certain security features, there is still a moment where a user must say that the program is allowed to run or install.

Since installation windows can be customized, a common trick is to make it seem as if a different program is being installed. Some windows actually pop up asking if the user would like to scan for spyware, or they pretend to be updates for the operating system. Once ‘yes’ or ‘ok’ is clicked, the spyware will install itself and perform its function.

What the spyware does can vary. Some records keystrokes and sends that data out, allowing the programmer to see any information your have typed in. Others install malicious pieces of software that re-direct your browser, making it seem as if you are on one site when you are in fact on another.

Fortunately, software programs have been written that will detect or uninstall spyware.

Spyware has a fingerprint buried the code that it executes. Though this fingerprint changes from program to program, there are ways to detect it. Software like PCTools Spyware Doctor search for these programs and attempt to warn you before they are downloaded and installed, or will uninstall them if detected running.

There is more spyware on the web now than ever before. The number of programs seeking to infect your system is constantly growing. The only defense against infection is a good anti-spyware program.
