Finally, scan your system again using the same anti-virus to ensure no malware is left. Make sure to update every credential and refresh everything. Try to remove traces from the past as much as you can. 

If any malware still remains, follow these steps again a few times. If the system is still infected, consult an IT technician to dig in deeply.

Understanding PC Threats

What Is a Computer Virus?

A computer virus is a malicious program that is intentionally written into a computer system to cause harm and spread from one device to the other. It can duplicate itself continuously by attaching itself to legitimate files and software, until it is stopped intentionally.

Why Are Computer Viruses Created?

Computer Viruses are created for many reasons including financial gain by selling you data, for teasing, or for political use.

How Computer Viruses & Malware Work

Malware and viruses get attached to useful software and spreads their virus on them too. By this, they continue to spread itself across other computers in the same network.

How Hackers Create and Spread Malware

They create malware by different techniques including injection, polymorphism, and encryption using any programming language like C++.

How Malware Spreads to Your PC

As the tech world is blooming, new types of viruses are also being used behind those complex systems to trick users into thinking that it’s a legitimate software/program. Below are some common ways on how malware spreads to your PC.

Can You Get a Virus Just by Visiting a Website?

Yes. If you visit an infected website, it’ll most of the times automatically download a malware on your device too. It’s recommended to use authentic websites only and scan other websites by any antivirus or research before clicking the link.

Infected Downloads 

Downloading any infected software spreads that malware to your device. When you visit a website occupied with hackers, or download any infected file shared by someone, the malware downloads itself on your system without even you knowing. That’s why, it’s important to use only trusted sources to download files and research other low-traffic websites first to ensure they’re secure.

Email Attachments & Phishing

According to research, email attachments are the most common ways of spreading the malware. Any unverified/unexpected email containing an infected attachment or a link can spread that malware to your system too. Always first scan the email attachments or links from trusted antivirus to ensure it’s safety (even if you know the person who sent it).

Removable Media (USBs, External Drives)

External media attached to the computer like USBs and external drives are also one of the most common ways to spread a virus, especially in older times. Infected media contains malware which is spread to every computer that device is attached to. Make sure to use removable media as less as possible, and from an authentic source.

Software Vulnerabilities & Outdated Systems

Software that haven’t been updated time to time are vulnerable to attacks by hackers. Hackers directly target outdated systems as they’re easier to hack and can’t be recovered by the latest technologies introduced by the companies. They also miss on the security changes by the developer company to keep the system safe.

Common Types of Viruses & Malware

As the world is advancing, hacking world is also increasing rapidly. New variants of malware are being used to hack systems. Few common types of viruses that you should be aware of are below:

Traditional Viruses

A malicious program intentionally written into a computer that can replicate itself to infect a computer system.

Worms

A type of virus which doesn’t need user to replicate itself over the network to other computer systems.

Trojans

Destructive programs that pretends to be a legitimate application, but harms your computer system as it enters it.

Spyware & Keyloggers

Programs that gather data from you without your knowledge and transfer it to hacker’s systems.

Ransomware

Malware that blocks and encrypts your computer’s files, and then demand a ransom from you to return them to you.

Adware

Software that bombards you with ads that display and downloads itself due to gathering data from your system

File-less Malware

File-less malware is a modern type of malware which infects your computer by injecting itself into system tools instead of traditional files. That’s why, it’s harder to detect it by traditional antivirus software.

Real-World Examples (Kaspersky, McAfee & Norton Research)

Real-world research from Kaspersky, McAfee, & Norton clearly show an increasing advancement in cyber threats. Their studies highlight a rise in ransomware, phishing attacks, and file-less malware that bypass basic security measures. These show the importance of using layered security systems instead of relying on antivirus alone.
