The Negative Impact Of A Computer Infection
A virus or malware will negatively impact your system, leaving you vulnerable to fraud, but the degree of impact depends on the infections type and scope. Here are some of the possible consequences of a computer infection:
- Loss of performance: Malware can make your computer process things more slowly, hogging system resources and taking far longer than usual to get work done.
- Loss of bandwidth: Botnets are networks of computers serving a central remote system, often distributing large volumes of data and consuming all broadband bandwidth.
- Loss of function: In extreme cases, the virus can degrade your computer performance or programming so severely that you can no longer use your machine.
- Exposure to other dangerous software: The purpose of some malware is to entice you to download even more dangerous software.
- Loss of information: Viruses might delete stored files or data, while ransomware may destroy your entire hard drive if specific demands arent met.
- Breach of privacy: Viruses sometimes seek to gather information for identity theft or fraud. This could result in financial losses if your accounts are breached and even punitive fines if your firm didnt follow local and state business regulations surrounding data privacy.
Tip: To address data privacy laws like the California Consumer Privacy Act and the EUs General Data Protection Regulation , conduct a risk assessment to see how well your business complies and where youre vulnerable to data breaches.

Common Types Of Computer Viruses
Some of the common types of viruses include:
1. Direct Action Virus: This virus is non-resident and functions by selecting one or more files in order to infect each time the code gets executed. The main aim here is to copy itself and spread infection whenever the code gets executed.
2. Boot Sector Virus: This virus infects computer systems by copying code either to the partition table on a hard drive or the boot sector on a floppy disk. During startup, the virus gets loaded into memory. Following this process, the virus will infect any non-infected disks accessed by the system.
3. Macro Virus: This virus is written in a macro language and infects Microsoft Word or similar applications and causes a sequence of actions to be executed automatically when the application is started or if it gets triggered by something else.
4. Memory Resident Virus: Stays in memory after it executes and after its host program is terminated. On the other hand, non-memory-resident viruses are activated when an infected application runs.
5. Overwriting Virus: Copies its own code over the host computer systems file data, which destroys the original program.

Is Chromium A Virus
As discussed above, a number of things that are called viruses are not actually viruses. Some of those, like ransomware or computer worms, are still malicious, but they are not computer viruses. Some things that are not malicious are sometimes suspected as viruses, and Chromium is a good example of this.
Chromium is not a virus. Chromium is a free open-source web browser project by Google. Much of the Chromium code serves as source code for Google Chrome, a legitimate and popular web browser. Just because you suddenly have Chromium on your computer doesn’t necessarily mean that its malware. You may have unwittingly installed a legitimate copy of Chromium that was bundled with other software.
Because Chromium is open-source, anyone can download Chromium and modify it to suit their needs. Bad actors could download Chromium and alter it to serve malicious purposes. WebNavigator Chromium browser is an example of a threat actor adapting Chromium code and using it as a search hijacker. However to reiterate, Chromium itself is not a virus.
Cyberprotection for every one.
What Is A Worm
A worm is computer code that spreads without user interaction. Most worms begin as email attachments that infect a computer when they’re opened. The worm scans the infected computer for files, such as address books or temporary webpages, that contain email addresses. The worm uses the addresses to send infected email messages, and frequently mimics the “From” addresses in later email messages so that those infected messages seem to be from someone you know. Worms then spread automatically through email messages, networks, or operating system vulnerabilities, frequently overwhelming those systems before the cause is known. Worms aren’t always destructive to computers, but they usually cause computer and network performance and stability problems.
