Protect and Prevent Computer from Spyware Infection

Spyware is malicious software (malware) that installs itself or runs on your computer without providing you with adequate notice, consent or control. It can monitor your online behaviour or collect your sensitive personal information such as personally identifiable information and passwords. It could as well display annoying popup advertisements, change your computer settings or cause your computer to run slowly. Because spyware does not obtain your consent before installing or running on your computer, and may not immediately display any noticeable symptoms after it infects your computer, you might not actually be aware of its presence in your PC.

There are many sources from which spyware and other malware could be introduced into your system. Spyware is most commonly installed through free software downloads, such as file sharing, screen savers and search toolbars. Also, they could be installed by websites, downloaded programs, or software you might install from a CD, DVD, external hard disk, or other removable media.

Some spyware can be installed from a website through an embedded script, or program in a webpage while some potentially unwanted software require your help to install through web pop-ups or free software that requires you to accept a downloadable file. In other words, you can get spyware installed in your computer without knowing it.

Let us take a look at the signs you should look out for to know if your computer has been infected by spyware or other malware:

1. If you notice new toolbars, links, favourites or bookmarked web pages, which you did not intentionally add to your web browser, you should know that spyware has sneaked into your computer.

2.When your default homepage, mouse pointer or search program changes without your intervention, it indicates the presence of spyware.

3. If you typed the URL for a specific website (for instance, a search engine), but you are redirected to another web site without notice, is a typical action of potentially unwanted software.

4. If pop-up advertisements are constantly displayed on your screen, even when you are not currently working on the internet, your spyware alarm should be set off.

5. Spyware may also cause your computer to suddenly start to run very slowly.

It is possible to not have any of these symptoms but yet, your computer might still be infected by spyware. You are therefore expected to take proactive steps to keep this form of malware at bay. By diligently taking the actions below, you are ensuring that you protect your computer from spyware infection:

# Run Up to Date Anti-Spyware Software – anti spyware software helps prevent malicioussoftware, spyware, and other potentially unwanted software or adware from installing itself or running on your computer. Antispyware program can also perform a computer scan to locate and automatically remove malware that might already be installed on your PC.

Windows Defender is a version of anti-malware software that is shipped together with windows operating system but there are other sources of anti spyware software including those which are customizable to handle all forms of malicious
software.

# Keep Your Computer Up to Date – always update the security features of your computer. To do this automatically, you need to turn your windows automatic updater on at all times. Similarly, you must visit your anti-spyware software publisher’s website often to check for and download updates of your software, to your computer.

# Review License Agreements Before Installing Software – before you download any free
software such as file sharing programs or screen savers, please read the license agreement carefully. Do not automatically agree to download any software offered by any website; rather look out for clauses where you might be required to accept advertisements and pop-ups from the company. In some instances, the software
publisher may require you to agree that the program will send certain kinds of information back to them. In such cases, if you do not trust the website, refuse to download such software to avoid installing spyware in your computer.

# When Pop-Up Won’t Close Except You Take An Action – sometimes a website could repeatedly display pop-ups asking you to install a toolbar, change your home page or take other similar action. The first action to take on such a situation is to try to close the pop-up browser window, if the pop-up still appears, right-click the internet explorer button in the task bar at the bottom of your screen and then click close group.

If every effort to close the pop-up window fails, as a last resort, close any other program you have open and restart your computer. No effort should be spared in getting rid of spyware because of the enormous threat it poses to the health and efficiency of your PC and your online safety. I strongly recommend that you follow these simple steps diligently to achieve the desired results.
