Worms, Viruses, Trojans, Malware, Spyware, Adware, Hijackers and more…
Sometimes these things are harmless and just make your computer become a total pain to work on, other times your computer could have some very serious issues that can cause complete data loss. Most commonly your computer will be infected with malware, adware and browser hijackers. We will go through a few of the different types of malicious software so that you can better understand if it’s time to bring it in.

Need Virus Removal?
A virus is a piece of code or a program that is installed onto your computer without user interaction. This software will run without your permission and is usually set to start automatically. Viruses have the ability to consistently duplicate themselves which will will decrease system performance with every copy. This is just a very simple type of virus but it can become very dangerous since it will force your hardware to run at 100% utilization, drastically decreasing the lifespan of your hardware.
Similar to the simple virus discussed to the left a worm is defined as a self-replicating malicious program that utilizes networks to transfer copies of itself to other devices on the network. This can cause harm by spiking bandwidth usage, attaching itself to e-mail attachments, shared network files and can also corrupt data.
Trojans are malicious software or scripts that do not duplicate/replicate themselves but have a different agenda all together. When trojans are activated either by user interaction or a startup script. They start to carry out the script that the programmer wanted the trojan to carry out. A trojan can unlock your computers security so that remote connections can be initiated to your computer. Trojans are most famous for data loss, system corruption and data theft.
Malware is an abbreviation for malicious software. Any software that will slow or disable computer operation, collects personal data or can create access to computers and their networks. Malware is an umbrella term for any software that does not fit the characteristics of the other categories.
Spyware works in the shadows. Spyware can gather information about computer activities and can gather and collect personal data as well. It is capable of searching and scraping hard drives for data to send back to the programmer. Spyware usually goes undetected since it is there specifically to data mine.
The most annoying of them all! Adware obviously displays ads, it usually redirects your home page to an ad littered search engine and will display ads all over your computer and browser. Adware usually redirects all your traffic through a proxy server where personal data can be obtained.
Browser hijackers normally redirect all your internet traffic to the initial attackers site where pop-up ads or other types of ads will display. Hijackers can also manipulate and take control of your network usage for their own purposes.
Ransomware is software that will block any and all access to your pc and network. The most famous and successful one of these was with the FBI labeled ransomware. Once you were booted up you were greeted with an image that you needed to pay the FBI a sum of money in order to unlock your computer. There are many different types of ransomware out right now and all they try to do is get you to give them your credit card information.
Everything you need to know about Virus removal and servicing
Virus detection is as important as virus removal. Viruses can make systems behave in a weird way (different from the way it is supposed to respond to commands) virus themselves are programs. Identifying a virus is very easy; this usually starts with your system taking a much longer time to complete tasks. Another indication that your system is affected with viruses is “popup windows” that occur very often and quite unexpectedly. Viruses generally slow down the overall speed of the system. Your system can get affected with a virus due to the opening of spam messages in your mailbox or due to pirated software.
Any malicious program can be called Malware; which is any program that disrupts the normal functionality of a computer. Some Malware is designed by Hackers with the intention of extorting money from your account through online sites, some are intended to crack passwords to your private and sensitive data.
Another potent threat comes in the form of spyware. Spyware collects information about a person or an organization without their consent or knowledge and sends it to another entity or organization. It can even collect the browsing data, your credit card or debit card information. Some spyware can slow down the internet speed and change the system settings.
Another malicious software comes in the form of Adware, or advertising-supported software. Adware generates ads in the system when the system is online. This is to generate revenue for its author.
A Trojan horse is very common among computer users. It is a type of virus that can steal data and other sensitive information from your system, also it acts as a backdoor for Hackers or controllers to enter your system and search for sensitive data. Trojans can cause serious trouble to your system. A Trojan horse unlike computer worms don’t replicate in the system.
Computer worms are standalone malicious programs that replicate itself to spread to other systems. It spreads through computer networks.
Computer hijackers can occur in many ways sometimes through a network connection or through physical access to the system.
Virus removal services can be received easily. Many antivirus software are now available in the market that can detect and remove most viruses. One can either chose their anti-virus program depending upon cost, need or can approach any Virus removal service business to clean up the system and protect sensitive data and information from the system. Each antivirus software has an expiry period. So this needs to be continuously renewed. It wouldn’t cost a fortune for home usage. No organization should run without anti-virus as the threat is overwhelming for IT professionals when a wide spread contamination occurs.
