How to Keep Out Malwares from Your Computer
Your computer is a valued device, your data is much more important than your computer. Both must be protected at all costs. The issue of computer malware confuses a lot of people.
The term malware is actually a shortened form of malicious software. Thus malware is software created or developed to damage or perform unwanted actions to your computer. Malware is also capable of disrupting your computer operations and gathering your sensitive information without your knowledge. Examples of malwares are:
- Computer virus
- Computer worms
- Trojan horses
- Rogue security software
A computer virus is a software program designed to interfere with the normal operations of your computer. It can corrupt or worse delete data on a computer making it impossible for you to access your documents. They spread rapidly from an infected computer to other uninfected computers.
They can also be infected to systems that are already infected making you end up with a mixed grill of viruses. They are easily spread via removable devices like USB flash drives, through Internet by downloading infected software or through email programs especially attachments.
A worm is a malicious software that propagates itself by replicating without the users interaction. Usually, it uses a computer network to pass from one computer to another. In most cases worms will originate from email attachments where they spread to the computer when the attachment is opened. They also send themselves as infected email messages to other computers. Worms are not as harmful as viruses but they end up consuming bandwidth of your network.
This is a software package that secretly gathers information from your computer through the Internet connection without your authority or knowledge. In most cases this is done for advertising purposes. They are capable of collecting your sensitive information like bank or credit information, user logins, and browsing habits.
Having acquired your browsing habits, you can then be bombarded with advertisements related to your surfing habits. Others can also install additional software, change your computer settings, and slow down your Internet connection speeds.
A Trojan horse is a malicious program that masquerades as a normal program inside other programs. It gains access to the computer by hiding itself in a legitimate program for instance a screensaver, free applications, and games from the Internet. Then, once inside your computer, it will put a code into the operating system and from there on you are at the mercy of a hacker.
Rogue Security Software
This is a software program that tricks you to think that your computer has a virus attack, thus it prompts you to buy or download a program that will clean your computer. These messages usually appears as pop ups which should be closed using the Alt + F4 key combinations. Always be extra careful before downloading any software from the Internet.
Why You Need An Anti-Malware In Your Computer
Many people will install an antivirus program in their system and think that they are 100% protected. That is what I have been doing until my computer was attacked by a Csrss.exe Trojan horse. Checking from the processes running, the csrss for windows service was having lower case letters while the Trojan had a capital C. The antivirus I was using could not detect it. The Trojan was turning word documents to have the .exe (executable) extension. So, it is only after opening such documents that I was getting a warning about an attempt to open a suspicious file.
Turning to the Internet, I decided to download malwarebytes, a free anti-malware, though you can also get a paid version. I used the free version which managed to detect and delete all the Trojan horses I had in my computer.
