Pastikan Komputer Anda Dilindungi Secukupnya!

Assalamualaikum dan salam sejatera,

Hari ini saya tak nak bercerita tentang apa-apa tips berkaitan kerja dari rumah. Tetapi ingin berkongsi dengan anda pengalaman saya terkena serangan spyware.

Beberapa hari lalu, komputer saya “sakit tenat” sebab telah dijangkiti “spyware” yang agak teruk. Ia bermula apabilan saya klik pada satu banner yang “smiley with voice” yang sangat comel. Bermula dari itu, saya mula didedahkan dengan pelbagai laman web berbentuk iklan setiap kali saya load website baru.

Setelah di scan dengan antivirus (saya gunakan sophos), tak banyak virus yang “mati” dan masalah belum selesai. kemudian, bila saya gunakan perisian spyware (dari pctools.com), rupanya ada beratus-ratus “makhluk perosak”yang ada kat komputer saya.

Alhamdulillah dengan tools PERCUMA yang saya downlod, ia dapat dipulihkan walaupun tidak sepenuhnya. Ia juga memberikan saya pengajaran agar mendapatkan perlindungan spyware selain antivirus, dan pastikan ia sentiasa up-to date.Apa itu spyware? Spyware ialah sejenis ancaman baru yang masih belum dapat diatasi oleh perisian antivirus biasa.

Nasib baik saya telah buat back-up segala maklumat penting ke dalam CD sebelum ini. Kalau tidak pasti saya akan lagi tension. Jadi, kalau anda belum miliki apa-apa antivirus atau spyware, sebaiknya dapatkan satu. Boleh jenguk-jenguk kat google.com untuk maklumat lanjut.

Apabila kita melayari internet, maklumat dan komputer kita sebenarnya mempunyai risiko yang lebih tinggi untuk terkena serangan ini. Jadi, hari ni saya akan kongsikan dengan anda satu artikel yang bagi tips bagaimana nak elakkan terkena spyware dan apakah tanda-tanda yang komputer anda telah dijangkiti spyware. Harap ia akan memberikan kita manfaat daripadanya.

Salam sukses!

� �Spyware Prevention

Prevention is the key to protecting yourself from spyware. If you have recently cleaned your computer of unwanted spyware, review the tips below to keep it that way. While these tips will help you prevent spyware, they are also examples of good habits that will help protect your privacy and security while online.

Be skeptical about installing strange or free software:
Make sure you know what EXACTLY is being installed onto your computer when you download applications off the Internet. Use the custom install option — if offered — to see the programs that will be placed on your computer with the downloaded application. Sypware is often bundled with many free software downloads. Make sure you know what’s in a package of software before you install it. Many of the file sharing or peer-to-peer programs include spyware in the installation package.

Pay Attention to Security Warnings:
“Security Warning” screens alert users to new software being installed from Web pages they visit. This software can include ActiveX controls and other executable files. You should not blindly accept such “Active-X” software installations; and be sure you trust the company installing the software. Here is a sample of a “Security Warning” screen that seeks a users’ permission to install the software. Just because the company’s “identity” is verified, it does not mean that you should blindly trust content from them.

Carefully read the license agreement or privacy disclosure if one is provided (clicking on the software name may cause these to be displayed). Often these documents will tell you what the software will do when it executes, such as sharing your personal data with a third party or displaying targeted advertisements. If you are uncomfortable with what the software might do or you are unsure about the company, you should decline the installation. Also, make sure the “Security Warning” screen links to an end user license agreement or other description of what you’re getting. Our sample “Security Warning” screen does not have one.”

Read the End User Licensing Agreement:
Almost all legitimate software installations will include an End User Licensing Agreement (EULA) that includes a lot of information. You should make a habit of reading these EULAs. Ideally, they should tell you exactly what they intend to install on your machine and the limitations to your use of the software. If the EULA is hard to find, or if the documentation is unreasonably difficult to read and understand, then maybe you should think twice before agreeing to install the software.

Practice Basic Computer Security Hygiene:
As a general matter, there are some basic security precautions you should take to protect your computer from hackers, thieves and cyber-terrorists. Following the three security tips below will help prevent all manner of programs from infecting your computer. For more details on computer security please visit our Computer Security section at http://security.getnetwise.org.

Always Use Anti-Virus Software:
And keep the software up-to-date. Over 500 new viruses are discovered each month. You are not just protecting yourself when using virus software, but also others you communicate with. Learn more about virus protection.

Always Use a Firewall:
A firewall is an “internal lock” for information on your computer. Many computer operating systems already have firewalls installed, you just have to turn them on. There are many other firewalls available to download or buy that help you secure your computer. Learn more about firewalls.

Keep Your Software Up To Date:
You should always make sure that the software on your computer is up to date with the latest security patches. The makers of your software probably offer security updates to your Web browser program, your email client and your operating system. Learn how to automatically update this software. Learn more.

Read the Web Site Privacy Policy:
Although sometimes very lengthy, the privacy policy provides important information about what information the business collects about you and how it is used. Learn more about reading a privacy policy.

Use Tools to Remove Spyware: Learn about tools that can remove spyware if you think it may have been installed on your computer.

Symptoms of Spyware
Source: http://spotlight.getnetwise.org/spyware/tips/symptoms.php

Below are just a few symptoms that may reveal that you have spyware operating on your computer.

Sluggish computer: If you’ve noticed that your PC has had a serious drop in its responsiveness lately, it could mean that spyware is draining its computing power.

New “favorites”: Spyware will often add “favorites” of its own to your browser’s favorites’ folder. If you notice an unusual number of new favorites and are not sure how they got there, spyware may be to blame.

Fishy pop-up ads: Pop-up ads from spyware software are designed to look like they’ve been served up by the legitimate Web site you’re visiting. As a result, you may not recognize them as a symptom of infection. There’s no way to be sure, but if the contents of the ads seem strange — or if you’re getting pop-up ads when you’re not even surfing the Internet — it’s very likely that they are being served up by spyware software.

Change of your default home page: One of the oldest spyware tricks is to automatically change your Web browser’s default or start-up home page. This is the Web page that appears when you start your browser or click the “home” button.

Unauthorized 1-900 number charges: If your phone bill charges you for 1-900 phone calls you didn’t make, you may have fallen victim to a particularly devious form of spyware. These programs will hang-up your normal Internet connection and instruct your computer to dial a 1-900 number — silently.
