Trojan horses, spyware, adware, ransomware, phishing, viruses, worms, rootkits, and browser hijackers are all types of malware.

Malware is usually picked up from the internet or through one’s email. Anything that one downloads from the internet can have hidden malware inside. Another source of malware can be hacked website commonly visited by the users. If a PC is underperforming, often crashes or shows a bunch of pop-ups it’s probably infected.

Computer Virus

Just like biological ones, PC viruses also enter one’s system unnoticed with a goal to take control over it. Computer viruses can be complex malicious programs or just pieces of code designed to make a mess. The greatest threat of virus is its capability to copy itself and to spread to other computers. Besides that, virus always attacks vulnerable parts of one’s PC until it takes over the whole system.

Viruses get to one’s PC through emails or downloads, but what makes them different is that they are well-hidden in some commonly used application. Once engaged virus starts spreading and multiplying itself. When more than one file is corrupted virus can make changes on one’s PC without being noticed. The best indicator for having a virus is bad or non-existing internet connection, and sometimes firewall and antivirus disabled.

Computer Worm

One of the nastiest malware one can get to his/her PC is a computer worm. This malicious application self-replicates all until one’s computer is impossible to use.

Computer worms are well-known for their enormous system memory usage. They can also spread through a network, causing bad network bandwidth. This goes on all until PC is no longer usable. The main source of computer worms is in file sharing. Any kind of data transmission can be a good way in for a worm. Transfer websites, attachments, file-sharing systems, emails, removable drives can all host a worm infection.

One of the best solutions to your worm situation is Shield Antivirus.

Just like the epic Trojan horse, its malware namesake was designed to fool its victims. You can get a Trojan almost anywhere, from your downloads and emails to all kinds of different content. Trojan is designed that way to make you think it is helping you with some task but instead is causing harm or stealing data from your PC.

You’ll notice you have a Trojan if your computer underperforms while working on some regular actions. This happens because of Trojan’s CPU over-usage. Anyone can pick up this malware from various websites, downloads, malicious email attachments, even movies, and music.

Deleting a Trojan might cause you trouble. Malicious data could be well hidden in any application/file that is affiliated with Trojan. The best way to get rid of it is by using licensed antivirus solution capable of wiping every bit of Trojan from the PC. A good prevention is also important. Stay away from suspicious emails or files with weird extensions. In order to stay on top of every potential threat, one should have Shield Antivirus which will provide information about any Trojan detected, solution to a problem, and of course – its removal.



Ransomware is a literal kidnap of your PC remotely. Hackers use codes to lock your computer. If you want to unlock it ransom has to be paid. Getting to this kind of situation is tricky and by all means unpleasant.

If you are infected, you’ll know it for sure. You won’t be able to access your PC and you’ll receive instructions how to pay the ransom. Since it’s been created by skilled coders, ransomware can lock your PC for good. The worse thing is that it can come from websites, emails, and networks as well.

Keeping everything up-to-date on your PC from the operative system to your protection software is one of the ways to protect yourself. Firewall you are using should always be up, especially when it comes to websites you are not familiar with. By using Shield Antivirus you can be sure any ransomware won’t get, though. The ones potentially hiding will be wiped clean from your PC before they can cause any damage.



Any type of malware that collects personal information, browsing history, and one’s surfing habits is considered a spyware. Its name comes from a great ability to hide. First of all, collected information is shared with the third parties and then it gets abused.

The most common way of picking up a spyware is by downloading files or software from unsafe websites. Spyware is bundled with files and unnoticeable upon download. Another way of being infected is by clicking on suspicious email attachments. The infection indicators are constant error messages, random appearance of icons on the desktop and automatic opening of tabs while browsing.

If one wants to prevent being infected it should pay close attention when downloading from file-sharing websites, opening random emails, and of course, keep his/her antivirus up-to-date. Shield Antivirus owns antispyware protection and at the same time is cleaning-efficient. The software keeps you safe and helps you resolve your spyware issues in seconds.



Most of the adware are safe and consist of annoying pop-ups showing on your computer and browser. Adware is a type of free software supported by advertisement. The danger of adware reflects in the possibility of one being tracked through websites he/she visits. In the worst case, his/her personal information could be gathered through adware.

Adware is distributed through free software one downloads from the internet. Usual actions performed by adware are advertisement showing on either desktop or browser, changed home page on one’s browser and ads popping up in applications that haven’t had them before.

A precaution that one can take in order to keep him/her safe from adware is simply having antivirus and other applications up-to-date and by using the firewall when surfing. If adware is already present in the system the best way of cleaning it is by using Shield Antivirus. Before you delete it, make sure you’ve backed up all the important data from your PC. Shield Antivirus will then scan the PC and liberate it from ads for good.


Browser Hijack

Browser hijack is a malware program that makes your PC develop a mind of its own by taking you to websites you have no intention to go to. In the same time, this malware alters your browser setting in order to lower your security level.

You’ll know your browser is hijacked simply by not being able to access your home page or a website of your choosing. Instead, you’ll visit some page placed there by the others. This malware usually comes from plugins one installs to the browser. Some browser hijacks can actually improve one’s experience online, but in most cases, it’s just boring.

Browser hijacks are easily avoidable. Not using third party applications is the best way to do it. With antivirus that can recognize it, you’ll stay safe as well. Shield Antivirus is a software able to both detect and remove browser hijack. You’ll be able to relax and enjoy your online experience without any concern for your browser being misused.

One of the most malicious software nowadays is the keylogger. An app capable of recording every letter one types while online. Every record is then being sent to keylogger’s creator which can analyze and use this data to retrieve one’s credentials, bank account numbers, credit card numbers, emails, etc. all in order to steal his/her identity.

Since this malware is well hidden, it’s almost impossible to know you have one. The only signs one can notice are slower mouse pointer or automatized letters/symbols showing on the screen, different from the ones typed. The source of keylogger can be in file sharing websites or email attachment. To be installed, keylogger usually needs some personal information. That’s why the victims are first exploited by phishing or social engineering. This malware is being installed without user’s knowledge so it stays undetected for quite some time.

The way to stay protected is simple. Pay attention to what and where you are downloading. To stay hidden, one can also use the virtual keyboard or alternate keyboard which can be confusing to a keylogger. Also, password management applications may help since they’ll do all the job for the user. No keys pressed, no keys logged. The only verified method of maintaining one’s security is, of course, trusted antivirus. Shield Antivirus has proven itself by tracking and removing keylogger malware, while at the same time providing real-time alerts to this type of danger.



One’s PC can be used remotely by hackers if it’s infected by the rootkit. The application may come from different sources. It allows a full access to one’s data, information, etc. The attack comes from the distance, with PC’s owner totally unaware of that.

Getting to know you are being used by a rootkit takes a lot of effort. By close monitoring of every invoked process on the PC, one can find out if he/she is being used. This takes a lot of time and an advanced tech-knowledge. Worse of all is that rootkit can be picked almost anywhere. Commercial apps or products that seem harmless are usually the greatest carriers of rootkit malware. The only good thing is that rootkit can’t replicate or spread by itself.

The only way to approach rootkit problem is by scanning the PC with up-to-date antivirus software. Any rootkit can be tracked and removed by Shield Antivirus. By keeping the program on, alongside with the firewall, one can be safe from any intrusion.



Thanks to phishing and social engineering cyber-criminals successfully scam people in order to gain money. Every suspicious offer that includes financial gain for the user can be a scam. By offering free stuff, credit cards or lottery criminals get the financial information of their victims. With personal information and bank records, even beginner hackers can steal from common users.

Scams use either flattering words or malware. One can become a victim all over the internet. Some scammers will just start communicating with you, while other will try to get to you through malicious software. Both ways have the same intention and can be seen in emails, websites, pop-ups, ads, etc.

The best way of protection is common sense. By using only trusted retail stores, not sharing your personal information with everyone, staying cautious online are all very good ways of staying safe. If by any chance a scam includes malware or any kind, then the antivirus is your best friend. Shield Antivirus has proved itself both in a lab and in the real-life situation. Thousands of satisfied clients confirm its performance and usability. By alarming you, scanning through your data and removing any potential threat Shield Antivirus keeps you away from any software-based scams.


Social Engineering

Since humans have their own errors, most of the time they are the main culprit of being hacked, used or scammed. Hackers know this and by using this human flaws they get to either one’s personal information or way inside his/her computer. By social engineering, a criminal can get to what he/she wants from the victims.

Any communication which occurs with no reason and coming from an unknown source can be considered social engineering. A hacker will send emails containing links, offers, warnings and similar, just to make the victim interact. When this happens, the extraction of personal information can start.  By using modern technologies and malicious software one can get more than enough within few emails. Usually this leads to identity theft or credit card number theft.

Since social engineering is not a program it can’t be deleted from PC. The best way to stay safe is by thinking twice when dealing with unverified emails, websites, and services. By not interacting with fishy content one can stay safe 100%. Just in case, it’s always good having an approved antivirus that can protect you from malware you might get thanks to social engineering. One software that has proven both in detecting and removal of malware is ShieldApps’s Shield Antivirus. With its smart detecting system, real-time alerts and high deletion rate Shield Antivirus is one of a kind software.



No-one likes to be bored to death with an advertisement. Spam’s main goal is exactly that! Advertising product/service you don’t want to know about through your email. Just like junk mail and pop-ups spam is usually not dangerous, but it’s tiring.

Every unsolicited email you get from companies, family and friends usually are spam. If it’s received on a regular basis, sometimes in tons, you can be sure you are infected. Even though it usually targets email accounts, recently it’s quite often on social media as well.

Users are the best spam protection, but this takes a lot of effort. A careful reading of every page, every installation or download can help from receiving spam mail, but most of us never do that. Unsubscribing from these “services” is also a way, but again it takes a lot of precious time. The best protection is having a spam filter or antispam solution in a shape of antivirus. Shield Antivirus is capable of stopping any spam content and as well informing you when you are about to “subscribe” to one. Leave it all behind with simple utilization of Shield Antivirus.



Phishing is a method used by cyber-criminals who want to come to one’s personal information. By sending fake emails or contacting people directly through scam websites crooks gain personal data. Login credentials, social security number, credit card number, bank account information are just some information interesting to the hackers.

By presenting themselves as some trustworthy company/organization, who’s services are being used by one, criminals ask for personal information. This action is usually covered with an excuse; an update of services, account error or similar. By filling in his/her information scammed person is giving away personal information which can lead to identity theft.

Since there are people standing behind phishing, it’s impossible to remove them. But, with enough attention and a good antivirus software phishing is avoidable. Make sure not to answer unsolicited emails, never open links, and pay close attention to domains of well-known websites. Shield Antivirus can’t stop you from answering fishy emails, but it will prevent malicious attachments from causing trouble.
