Viruses Have Friends Called Worms And Trojan Horses
Unlike viruses, which spread from file to file, worms spread from computer to computer through the Internet, often by sending themselves to everyone in your address book. Passive worms need some action from you to get to work, such as opening an e-mail attachment. Active worms take advantage of vulnerabilities in a system to run on their own. Simply opening an e-mail or previewing it can launch these aggressive bugs.
Yet another form of virus, a Trojan horse, gives the appearance of being an innocent game or screen saver but can destroy files or let hackers in the back door. While a Trojan horse doesn’t automatically spread, it still can cause significant damage.
Trojan horses are often used to steal personal information. Some of these viruses can lift passwords and user names by installing a keylogger while you’re busy with the “fake” program it traveled in under. A keylogger can record your keystrokes and send this information elsewhere.
Patch Your Operating System And Applications
Tech companies routinely put out software updates to make their devices or software safer to use. Without these updates, cybercriminals can abuse security flaws and force a device to download a virus.
This cyberthreat is called a software vulnerability. You might be careful to avoid viruses on the internet, but a software vulnerability may lurk in the background of your computer. The only way to ensure youve covered this risk? Regularly update your software whenever a patch is available. Or you can adjust your computer settings to accept updates automatically.

Examples Of Computer Viruses
In 2013, the botnet virus Gameover ZueS was discovered to use peer-to-peer downloading sites to distribute ransomware and commit banking fraud. While tens of thousands of computer viruses still roam the internet, they have diversified their methods and are now joined by several malware variants like:
-
Worms – A worm is a type of virus that, unlike traditional viruses, usually does not require the action of a user to spread from device to device.
-
Trojans – As in the myth, a Trojan is a virus that hides within a legitimate-seeming program to spread itself across networks or devices.
-
Ransomware – Ransomware is a type of malware that encrypts a users files and demands a ransom for its return. Ransomware can be, but isnt necessarily, spread through computer viruses.
Turn On User Account Control
User Account Control a fundamental security component on Windows. It can mitigate the impact of malware. When some changes need the administrator-level permission on your computer, UAC will pop up and give you the choice to refuse or approve the change.
If you are not sure whether your UAC is enabled, you can check it:

Clear Your Browsing History
Your mobile web browser has a browsing history, too. Clear it often including cookies and cached files to give hackers as little information as possible to work with if they do break into your phone.
Key takeaway: Mobile devices require additional efforts to protect, including deactivating certain features when theyre not in use and installing security applications.

Require Employees To Use Strong Passwords And Change Them Periodically
Creating a strong computer password or phrase is perhaps the easiest way to enhance the security of your system. Set up a complex password or phrase from 8 to 64 alphanumeric characters, and use special characters such as #@*& . Remember, passwords should never be written down and stored near your device. When possible, adopt a two-factor authentication strategy.
Updating your password periodically may help prevent brute force password cracks. A brute force attack is a trial-and-error method, where a program attempts to decode a password and gain access to a targets computer. The stronger your password or phrase is, the harder it is for a hacker to crack it.

What Are Computer Hackers
Computer hackers are people who break into internet-connected devices such as computers, tablets and smartphones, usually with the intent to steal, change or delete information.
Just as other thieves have malicious intent, hackers usually find their way into devices for negative purposes. Hackers may want to steal, alter or delete information in your devices, and they often do so by installing malware you might not even know is there. These thieves might get access to your most precious data before youre aware of a break-in.
Key takeaway: Hackers are interested in gaining unauthorized access to your devices to steal sensitive data.
Symptoms Of A Computer Virus
We can take all of the steps there are to prevent computer viruses, but an infection can sometimes just happen, and they can slip past your defenses. And when they are in, they arent exactly rushing to tell you that. There are however, some tell-tale signs that your computer has been infected with a computer virus:
- Computer has an unusually slow performance
- Unexpected and frequent crashes
- Increased number of pop-ups on seemingly normal websites
- Unfamiliar programs that prop up when you turn on your computer
- Changes to your homepage

Tips To Protect Your Computer From Viruses And Malware
It may be a new year, but an old scam is making the rounds of online computer users.
The FBI recently issued a warning about a computer scam that starts on the telephone: You get a call from someone claiming to work for a major software company. They tell you your computer is sending error messages to them over the Web, and theyve detected a virus. No problem, however: All you have to do is pay them a fee and theyll remotely fix your computer by installing anti-virus software on it.
Once the caller has your credit card number and access to your computer, they dont remove viruses, however they install them.
In October, the Federal Trade Commission cracked down on a similar scam that charged computer users from $49 to $450 to remove malware from their computers. The agency estimated tens of thousands of computer users fell prey to that scam.
The way to defeat these scams is simple enough dont give strangers your credit card numbers or access to your computer. But lets take a look at eight additional ways you can protect yourself from viruses and malware:

Dealing With Malicious Software
Malicious software includes viruses, spyware, adware, trojans and various other subtypes of nasty software packages.Well go over each type of malicious software and then also cover how to either avoid or fix the issue.
Computer Viruses
Quite possibly the best-known form of malware, a computer virus is a self-replicating piece of software that spreads from one computer to the next through disks, drives and email. Viruses are not standalone programs. Instead, they usually tack themselves on to another legitimate program and execute their code when you run that program.
Apart from making copies of itself to infect new computers, viruses also have a payload. This can be something harmless or mildly irritating, such as a message that pops up to laugh at you or it can be serious. Such as a virus that completely wipes all your data.
The good news is that viruses cannot spread themselves. They need help from you! The first and most important safeguard is antivirus software. Windows Defender, which comes with Windows 10, is perfectly adequate for most people, but there are many choices out there. While macOS and Linux viruses exist, these markets are relatively small, so virus creators dont bother too often.
Thats changing however, and if you do use one of these operating systems its a good idea to find an antivirus package you like, before their increasing popularity brings a flood of new opportunistic viruses.

Ransomware
Worms
AdWare & Spyware

Keep Your Software Up To Date
Software makers like Microsoft and Oracle routinely update their software to fix bugs that could potentially be exploited by hackers. Oracle just released on Sunday an update to its Java software to fix a security hole hackers could have used to infect computers with malware.
The software patch came after the Department of Homeland Security sent out an advisory late last week about the security flaw recommending computer users disable the Java plug-in in their Web browsers.

Use The Internet With Caution
Even the safest websites can contain spyware and malware. All it takes is one click of the mouse for your computer to become infected. Many phony websites are camouflaged to mimic authentic websites.
When entering URLs, check the name and correct spelling of the website. Avoid clicking on popups, ads, graphics, and links to other websites.
Using Computer Security Programs
Computer security software will protect your computer against viruses, worms, Trojans and many other kinds of malware that can be transmitted by diskettes, CDs, DVDs, USB sticks, and your Internet connection. Most computer security software work according to the same principle whenever you connect to the Internet, the program will update its virus list.
Virus lists are maintained by the manufacturers of the software, listing known viruses and malware. As long as the virus list of your computer security program is up to date, your computer is fairly well protected against threats. However, since new viruses are created all the time, even the best computer security programs may not find the latest ones. Having an computer security program running and updating its virus list are only a couple of measures with which you can improve your safety they do not diminish your need to be careful.
Computer security programs have so-called run-time virus control checking your computers file system actively all the time. When it finds a virus, the program will warn you with a pop-up window, where you can select to remove the virus from the file or even to delete the whole file. Be careful when you respond to the program.

Importance Of Cybersecurity For Remote Workforces
The COVID-19 pandemic has driven the global adoption of remote work as a new, potentially transformative norm. But remote work also represents a golden opportunity for cybercriminals, who have found employees working from home, under loose supervision, to be soft targets for hacking. Hackers are using increasingly novel, sophisticated tools. But more mundane exploits, including oldschool malware and socialengineeringmethodssuch as phishing and vishing, are seeing a resurgence as remote employees or contractorspreoccupied with work and inexpert in cybersecurityprove vulnerable.
Remote employees are soft targets for hackers and cyberspies.
Mid-level employees have difficulty thinking of themselves as targets for industrial spies or state-sponsored cyberspies. Construction firms have also been targeted by hacks and ransomware attacks. The manufacturing industry, long considered lax in its cybersecurity standards in comparison to other industries, had by 2020 become the second-most targeted industry for ransomware and data-theft exploits, after financial services.
Learning Good Cybersecurity Habits
When were young, our parents teach us general rules for life meant to keep us safe. Always look both ways before crossing the street. Never get in a car with a stranger. That sort of thing.
Sadly the technology of today didnt exist when many of us were young, so theres a definite need to have the same sort of common sense, but adapted for the digital world.
Use Strong Passwords & a Password Manager
Passwords are still one of our best defenses against getting hacked. Most sites will have a minimum password complexity. For example, theyll say a password must be a certain length and contain a particular mix of character types. Sadly, any sort of password that a human being can easily remember is likely to be one that can be broken through brute-force guesses sooner rather than later.
The best thing you can do to protect your computer from hackers is use a trusted password manager. These managers keep track of all your passwords securely and will generate randomized strong passwords that are almost impossible to guess using brute force or any other password cracking method.
The good news is that most people dont have to go looking very far for a password manager. already has a very competent one built in. You can generate strong passwords within the browser and sync them to the cloud. So wherever youre logged into your Google Account, you can retrieve passwords with ease.
