Different types of malware and the purposes they are used for

A computer should always be running in top condition. Over time, memory (hard drive) usage may impact a computers speed. Otherwise a well taken care of computer should stay in good shape. However, a computer infected with any type of malware can impact the performance of a computer, in some cases making it unusable. The underlying goal of malware and why it’s created is for stealing information and mostly profit (stealing money).

This section describes different types of malware, why it exists, and where it comes from so you can understand it and have a better idea on how to keep your computer safe. All malware can generally spread the same way. Infected websites, spam email, infected programs the user downloads, and a weak or no firewall. Smartphones can be infected with malware although it is less common.


Any type of software that is harmful to your computer. Obtained by downloading files/programs that seem harmless, opening or following through with spam email instructions, or visiting bad websites. Every definition in the list below is malware. A virus, worm, and trojan are all different types of malware even though a virus is often used to describe other types of malware which is technically incorrect.


A computer virus is attached to a .exe file and is only ran while the infected file/program is running. A virus can run in the background remaining undetected if the user does not know how to check processes. A virus requires a user to run an infected .exe file to spread and infect other programs and computers while a worm can spread by itself. The payload of a virus can range from displaying messages on your screen to deleting critical files as well as infecting the computer with other malware. A virus can be obtained by visiting websites infected with malware. Android uses .apk files for apps so technically viruses do not exist on android but other types of malware do.


Unlike a computer virus, worms can spread by themselves without running a .exe file. A worm can infect your email contacts and send copies of itself to other networks and computers. A strong firewall is important to prevent worms along with other security measures.


Usually hidden inside of a download, email, or an infected website (drive by download) that seems harmless. A trojan can create a back door. Allowing the trojan to gain remote access to the computer. Unlike a virus or worm, a trojan does not copy itself or spread. A trojan can drastically slow down a computer due to processor and network usage. A trojan can also be used to infect a computer with other types of malware such as a keylogger, or turn the computer into a bot for ddos attacks.


Ransomware is malware that encrypts (locks) files on a computer (or sometimes the entire hard drive) and will only decrypt them or not publish them if the user pays the demanded amount of money. Some ransomware can be reversed if it’s not that advanced and most likely created by a script kitty which is a term for a amateur cyber criminal. Otherwise, serious ransomware will encrypt the files making it highly difficult to reverse. This is why it is always important to back up important information such as pictures, files, videos, and whatever else that has high value. The use of ransomware has grown between the years of 2012 and 2014. Ransomware is usually a trojan disguised as a safe file.


A bot is a computer that has been compromised by a hacker or malware and is used to send out email spam or a ddos attack and is usually controlled remotely. When multiple computers are compromised and used for malicious purposes, it is then called a botnet. People may be unaware that they have a compromised computer.


A malicious program that is used to record what the user types. It is often used to crack passwords and other information such as bank or credit card information.


Malware used to monitor web browsing habits such as what websites the user visits and what they search for. Spyware can collect information without you knowing and then sell it to other company’s. Spyware does not spread like a virus. It is installed by exploiting security holes and can also be hidden inside of programs and files.


Adware is malware that places unwanted ads and pop ups on your computer while your on or offline. Adware can track a users internet activity and record information without the user knowing. The data that is collected is usually sold to third party’s. If you are infected with adware then you might notice unfamiliar toolbars in your browser. You may also be redirected to ad pages when using your browser. Alot of free software contains adware so be cautious when downloading programs.


A rootkit is a malware program that can modify the operating systems and programs. It is designed to hide software. It can be hard to detect and sometimes very complicated or nearly impossible to remove.


A bootkit is similar to a rootkit. Bootkit are also hard to detect and remove. A security exploit in Windows allows the bootkit to infect and hide itself in the master boot record or the volume boot record. Anti virus may not detect a bootkit because the bootkit is not located in the regular files where the anti virus scans.


Different web browsers

A web browser is a program that is used to access the internet. A web browser is always pre installed on any PC operating system or mobile operating system. It is the program that you use to listen to music, watch videos, and read email. A Mac(PC) and iOS(I phone) both come with their own pre installed Safari browser. Linux and Windows also come with a pre installed browser. Linux usually comes with Ice Weasel which is a variant of Firefox. Windows comes with a pre installed browser called Internet Explorer. The newer Windows browser is called Microsoft Edge which has new security improvements. Android comes with a basic pre installed browser. The Safari browser is unique to Apple and can only be installed on Apple devices, unlike Google Chrome and Firefox which can be downloaded on other devices. Each web browser has it’s own functionality but the settings on popular well known browsers are relatively the same. Some other unpopular web browsers don’t have the best security and therefore shouldn’t be used. This is a list of the most popular and most used web browsers.

Internet Explorer

This is the web browser that is pre installed on Windows operating systems. It was first introduced when Windows 95 came out. Internet Explorer dominated the market for so long until other browsers like Chrome and Firefox started gaining ground. It isn’t the most secure browser compared to others which makes people not want to use it.

Microsoft Edge

This is the new browser introduced in 2015 when Windows 10 came out. The browser has significant security improvements over Internet Explorer.

Mozilla Firefox

Created in 2002 under the project name Phoenix by the Mozilla community. It was released in 2004. Mozilla Firefox was the first browser challenge Internet Explorer’s dominance. Available for MAC OS, Windows, and Linux. Firefox for iOS was released in late 2015. All of these platforms use the Ghecko layout to render web pages except iOS due to Apple’s restrictions limiting other web browsers like Chrome to the web-kit based engine built into iOS.

Google Chrome

Developed by Google. Google Chrome was first released in 2008 for Windows and was later made available for Linux and MAC.

Opera Browser

Developed by Opera software. Available for MAC, Linux, and Windows. Out of the web browsers listed it is the least popular browser. It had a reputation for being a slow browser with to many features for a while until recently. The new version has significant security improvements over the earlier versions. It is now considered a decent web browser but It is still at the bottom of the popularity list.

Is 4k worth it?

Is now good time to buy a 4k tv? That depends. 4k tv’s have become more affordable recently and are being pushed as the hd standard. 1080p tv’s aren’t being produced as much as they were. Some are still made but they are budget, smaller sized tv’s. If you need a new tv then a 4k tv makes sense however if you’re thinking about upgrading to 4k from a decent 1080p tv then it may not be as amazing as it sounds.

4k has four times as many pixels then 1080p. 4k is known as 2160p. A 4k tv has 2160 rows and 3840 columns of pixels. 1080p is 1080 rows and 1920 columns of pixels. In order to view content in 4k you need a device that’s 4k compatible such as a ps4 pro or a 4k blu ray player. Otherwise it won’t be in 4k such as a blu ray player or ps3. However, Netflix and other services have started to stream content in 4k which is a plus. A 1080p tv is already HD. You also need to be sitting close enough to notice the difference. If you are sitting from more then about 7 feet away, which is the normal viewing distance then you probably won’t notice much of a difference.

So the decision is up to you. It all depends on what you already have and if you think it is worth it. You can take this advice or also use judgement. In the end it’s your choice. Since they don’t make many 720p or 1080p tv’s anymore and they price isn’t that high for 4k then it might be worth it. Just know that if your sitting close to the tv you won’t notice a big difference which is the reason why you would need a relatively large tv so that you can be within the proper viewing range to notice the 4k difference.

ps4 vs xbox one

Ps4 and Xbox one have been the new generation consoles for a few years now. They can both do alot of the same like watch movies, play games, use apps like Netflix, and play online. Both systems are similar in what they do however sometimes one can have the advantage over the other in certain departments. Here we are going to look at the differences and how each system compares to one another. We’re going to be comparing the original ps4 and Xbox one along with the newer ps4 pro and Xbox one x. The main update is hardware and graphics with everything else relatively staying the same.


Video game graphics have gotten pretty advanced. With the latest generation consoles, game developers are able to display high definition graphics with alot happening at once. Here we’re going to compare the original ps4 and Xbox one and then the ps4 pro and Xbox one x since the newer models have updated hardware and graphic specifications

Ps4 vs Xbox one – The ps4 and and the Xbox one Both have similar graphics just like the ps3 and Xbox 360. Ps4 has more games in 1080 p then Xbox one does. The ps4 is significantly more powerfull in terms of hardware and graphics giving it the slight edge in graphics. However side by side both systems look great.

Ps4 pro vs Xbox one – Microsoft outdid themselves with the Xbox one x due to competition with the ps4 pro. The Xbox one x plays games closer to native 4k resolution then the ps4 pro. For example the evil within 2 is 1800p on the Xbox one x and 1280p on the ps4 pro. Ps4 does a good job at upscaling and comes close to 4k but the Xbox one x displays the highest resolution. You won’t be able to notice a huge difference overall but certain games do look better on the Xbox one x. Also because of the stronger hardware, game developers can push the graphics and do more with the Xbox one x then the ps4 pro currently and in the future.


The hardware between the updated higher resolution consoles and the original consoles is significantly different so both are going to be reviewed.

Ps4 vs Xbox one – The original ps4 outperforms the Xbox one in terms of hardware. The ps4 uses a AMD cpu processor clocked at 1.6 Ghz. The gpu is 1.84 teraflops. The gpu has 18 compute units at 800 mhz. The Xbox one uses the same processor clocked at 1.75 Ghz. The gpu has 1.3 teraflops. The gpu has 12 compute units clocked at 853 mhz making the ps4s gpu about 50 percent stronger then the Xbox one. Both have standard blu ray drives.

Ps4 pro vs Xbox one x – This time it’s the other way around and the Xbox one x significantly outperforms the ps4 in terms of hardware which is why it’s more expensive. Xbox one x has a memory bandwidth of 326 Gbps while the ps4 pro has 218 Gbps. Both have hefty one terabyte hard drives. The gpu of the Xbox one x has 6 teraflops while the ps4 pro has 4.12. The Xbox one x has 12 gb gddr5 ram. The ps4 pro has 8gb of gddr5. The Xbox one x has a cpu speed of 2.3 Ghz. The ps4 has a speed of 2.1 Ghz. Both use custom 8 core processors. Xbox one x has a drive for 4k movies while the ps4 pro only has a blu ray drive.


The price for both online memberships is around the same. The price may have changed after this article was posted. You need online to play any online multiplayer mode. Both online memberships have perks like receiving two free games per month. Don’t expect anything crazy the games are usually older and not expensive.


The original Xbox one is cheaper then the original ps4, however due to the competition between Sony and the ps4 pro Microsoft made the Xbox one x more powerfull which set the price tag at about 100 dollars more then the ps4 pro. At the time of this article the ps4 pro is $399.00 and the Xbox one x is $499.00


In most peoples opinion the ps4 has the better game selection. This doesn’t mean Xbox one doesn’t have good games. It simply just means that ps4 has more exclusive titles and remasterd titles from ps3. The Xbox one uses an emulator to play 360 games. Most popular titles for the 360 are available.


The ps4 controller doesn’t need batteries. The Xbox one x controller needs batteries unless you buy a $25 battery pack.


The virtual reality for the ps4 takes the lead for extra features and innovation. The connect for the Xbox isn’t as successful. The Xbox one can integrate your cable box signal to easily switch between games and tv.

Xbox one s

Xbox one s can stream video in 4k. It can also play 4k blu rays. It upscales games to a higher resolution like the ps4 pro.

So which system should you choose? Well it’s all about preference. Ps4 does have the better games but that is still just an opinion. In the end both consoles can pretty much do the same with the main difference being games and features like virtual reality. The desicion is up to you. I would recommend the ps4 based on games and because without batteries the Xbox one x controller needs a $25 dollar charging kit.
