Considerations to Take Prior to Purchasing An Antivirus Program

For sure, you are aware of the fact that your computer devices are prone enough to get infected with viruses and some other threats when you go online and download something from the web. Viruses can even be acquired in just simply connecting a flash drive and SD card into the system of your computer. This is the main reason why your computer devices must have an antivirus program, which will protect them from viruses and some other threats. But the big question is, how can you have a reliable and fully functional antivirus software. Well, here are the considerations that should be taken prior to purchasing antivirus program:

The Features

This is the very first thing that must be taken into consideration before buying any antivirus program. Keep in mind that there are a lot of antivirus softwares being sold these days that are excellently crafted by different developers. Because of this, each of them surely varies when it comes to features. The truth is, almost all of the antivirus programs are packed with basic features like USB drive scanner, email security, antispyware tools, and scheduled scan. There are also many more amazing features in some softwares. Hence, you need to know what features you really need, and then decide what is worth buying.

The Performance and Compatibility

The resource usage and your computer’s hardware configuration are very important when buying an antivirus program. In case you have an older version of a computer, then there is a bigger tendency that it only has a lesser memory or RAM that may not be enough for the antivirus program that you want to download in your computer device. This is the main reason why you have to know first the system configuration of your computer prior to downloading your chosen antivirus. Always keep in mind that having a wrong antivirus software can be the reason why your computer slows down.

The Malware Detection Capacity

The truth is, there are so many threats that can harm your computer system aside from the most common viruses and worms. There are those Trojan horses and rootkit that are capable enough in hiding themselves, making them to be undetectable for ordinary antivirus programs. These threats are sure enough to cause some severe damages on your computer. Because of this, you have to buy an antivirus software that can be able to detect and delete these kinds of threats.

The Price

The last thing that you have to take into account is the price of the antivirus software. Needless to say, antivirus programs vary when it comes to prices apart from the features and developers. You do not want to spend your hard earned money to something that is not worth it, right? If you are on a tight budget, then you need to find an affordable antivirus software without needing to compromise its functions and reliability. Remember that an expensive antivirus does not mean that it is already a reliable one. It’s not all about the price actually. It’s all about the performance and usefulness of the antivirus on your part.

These are the considerations that you need to take prior to purchasing antivirus program. You can never go wrong if you consider these things.


Know and Prevent Remote Access Trojan (RAT)

Trojan horses are commonly known as harmful programs, and Remote Access Trojans (RATs) are the latest evolution of such programs. Typically, a Trojan horse would access a computer system in the disguise of some other software and transfer data from user’s computer to the hacker’s computer in the background. Remote Access Trojans are one step ahead, they offer remote access to the hackers. RATs are kind of like access gateway to a computer, without the consent of the computer user. RATs are quite difficult to detect even using anti-malware programs, but there are ways you could prevent RATs from getting into your system.


RAT Working Method

Like typical Trojan horses, a RAT would get settled into a computer through an executable installer file and install in a computer like any regular program. RATs would have the face of some other program and they are so carefully implied, even careful and experienced computer users might often mistake a RAT for a regular program. However, like any regular software installation, a Remote Access Trojan will make registry and system service entries as well. This way, even an antivirus program will treat a RAT as a regular computer program and exclude the data transmissions from suspicion list. Trojan horses communicate through the ports so internet connection is required for a RAT to operate.


By following the methods mentioned here; a computer user could stay safe from RATs.

  • Active Firewall and Antivirus Programs: Firewalls keep eye on the internet connection and data transmission, and hence they have the ability to track RATs. Any unauthorized port setup and opening request will be tracked by a firewall and the user would be prompted to take an action. Upon verification of the legitimacy of the request, computer user could block or allow a program with the port request.
  • Assess Running Processes: Chances are, a RAT won’t appear in the running applications list in Task Manager window; however it can’t conceal itself from the running processes. Open Task Manger by holding down Ctrl+Alt+Del together and clicking on Task Manager from the window that appears, or simply right click on the Taskbar and click Task Manager. Click on Processes tab and find out any suspicious process that doesn’t look right, and click on ‘End Process’.
  • Unusual Programs in Startup: To begin with, lots of programs in the Startup list isn’t a very healthy computing practice because it makes a computer slow when it boots up. However, look for the program list and check whether any unusual program is enable for Startup initiation. A user won’t click on RATs to execute them so automated execution is necessary, and that’s why these programs typically use the Startup option.
  • Abnormally Slow Internet: If your internet connection remains slow most of the time for no good reason, chances are some programs in the background is using the bandwidth. If it’s not a regular update activity by your security or other installed programs, chances are a RAT is using the bandwidth for intrusion.
  • Check Installations: Check the list of installed programs in your computer inside Programs and Feature. Uninstall all the programs that you don’t need.


User awareness could alone save a computer from RATs, and using a security program always comes useful for safe computing.
