What is a virus?
A computer virus is a malicious code that alters other computer programs and files by infecting them with the viral code. The more the infection, the more the virus replicates and multiplies. Depending on the viral code, viruses can range from an annoyance to very destructive entities. The latter is more common and comes in various types.
Types of viruses
Viruses come in many variants, each designed for a specific destructive function. Most common types include:
- Boot Sector Virus – This is a virus of the early days, and its infection is not common on the latest devices. This virus infects the MBR or the master boot record. It gets its way into a system by first infecting the boot sector on a disk or the executable boot file on USB drives.
- Cavity Virus – This virus fills empty spaces of code in applications with its code. Since it utilizes empty spaces, this virus does not affect the size of the file or program it infects. This makes it evade antivirus scans that look at the size and date of modification of files.
- Non-resident Virus – also referred to as direct action virus, this virus is designed to infect files and then delete itself. It does not hide in the computer’s main memory and does not affect the performance of the system. This is the easiest virus to create and to get rid of. It is also one of the most common virus.
- Resident Virus – this is a type of virus that hides in the computer’s main memory. This virus infects targets such as files by intercepting operating system requests and directing them to the replication module. This type of virus is hard to detect and find since most antivirus software does not scan the main memory.
- Macro viruses – also known as document viruses, these are viruses that embed themselves in documents that support Macro programs. The virus infects targets after the document is opened. This virus is common in email attachments.
- Multipartite Virus – most viruses operate in a single-mode but multipartite viruses operate in multiple modes. That is, they spread through various ways and infect both files and the master boot record. They are also known to deliver multiple payloads. Multipartite viruses are too hard to get rid. If you clean the infected files, the virus still replicates from the boot sector.
- Overwrite Virus – as the name suggests, this type of virus infects files and applications by overwriting them with its code. This makes it impossible to recover the infected files.
- Polymorphic Virus – this virus type changes its pattern when it replicates – its code changes while maintaining its functionality. This makes it evade antivirus scans and hence hard to remove.
How to know if your device has a virus?
Without performing a system scan, it can be easy or hard to know if your device has a virus. For instance, some viruses remain dormant until an infected program or file is executed. Additionally, the modes of propagation used by different viruses make them hard to detect. If a virus infection has taken root, your device might start displaying some of the telltale signs below.
- Slower system performance – viruses may impact the performance of a device as they carry out their operations. This might result in an overheating device, a freezing device, and crashing of most applications. If it is a portable device, you might notice faster battery drain than usual.
- Unauthorized operations – a virus might open programs or files to continue replicating and spreading the viral code. Viruses might also cause applications to crash, and even your device starts to act up.
- Loss of disk space – as viruses replicate and infect more files, you might go little on space unexpectedly. You might also notice that some files have many duplicates, or there are new files you are unaware of.
- Sudden loss of files – besides the multiplication of files, some viruses are designed to delete files and programs. If you notice some files or programs are missing, and you did not delete/uninstall them, you might have a virus on board.
How to remove viruses from your device
The surest way to deal with viruses is by using an antivirus or antimalware software. This software is engineered to detect most viruses and get rid of them. The most recommendable tool is Malwarebytes. To remove viruses from your device using Malwarebytes proceed as follows:
- Download and launch Malwarebytes Antimalware software.
- On the Dashboard section, click the Scan now button to perform a threat scan.
- On the results that show up, select the items you want to quarantine/disable, if any.
- Click the next button to select preinstalled software you want to quarantine/disable – the detected software might be the one injecting viruses.
- Lastly, click the Quarantine button to move selected items to the quarantine section.
- If you want to get rid of the detected items, open the Quarantine section, and click the Delete button.
Some viruses might be invisible, and if still the device is showing some telltale virus signs, proceed to the next section.
Delete viruses in Safe Mode with Networking
In Windows machines, some viruses are designed to load up as services when your computer starts. These makes them undetectable by antiviruses. To remove these viruses, you will need to start your Windows in safe mode with networking. To do that proceed as follows:
- Shut down your computer and start it again while pressing the F8 key for ‘Advanced boot options’ menu
- Select ‘Safe Mode with Networking’ and wait for windows to boot up.
- Click the Windows logo and type ‘temporary files.’
- On the results that show up, select ‘delete temporary files’ and proceed to delete the temporary files.
- Connect to the internet, download, and install Malwarebytes.
- Do a system scan, delete detected threats, and restart the computer to boot up in normal mode.
If still, your device shows up virus signs, it is time for clean reinstallation of the operating system.
