What is Virus Removal?

what is virus removal

Virus removal refers to the process of automatically or manually disinfecting or deleting a computer virus, malware or any other malicious program on a computing device. The process is employed to shield a computer from possible data loss, corruption, or system inaccessibility.

A system virus removal follows the virus scan phase, which detects the virus and threat level. The virus can also be manually deleted, but this will need a strong understanding of viruses and the correct skills to reverse or remove registry entries. The user receives a failure message if a virus cannot be deleted.

What is Virus Protection?

Virus protection software has been designed to prevent viruses, Trojan horses and worms from getting onto a computer and also to remove any malicious software code that has already infected a computer.

Most virus protection utilities bundle anti-malware and anti-spyware capabilities to go along with anti-virus protection. Internet security suites go one step further by including additional capabilities like anti-phishing, firewall, anti-spam, PC optimization, and file protection.

What can You do to Get Virus Protection?

Ensure to always keep your security software active and updated New viruses are released almost every day and hence there is always a chance for your computer to get infected by a virus that your antivirus software does not yet “know” about. 

Regularly update all your software You need to keep your computer’s operating system and other software updated because viruses often propagate by exploiting flaws in operating systems or commonly used programs. Whenever possible, configure your computer to download and install important updates automatically.

Deal with e-mail carefully Viruses are often propagated through e-mail attachments. Do not open attachments unless you are reasonably sure the e-mail is a genuine one

Only use e-mail services capable of scanning messages for viruses

Refrain from installing spyware and other software that may open backdoors which can be exploited

Types of Computer Viruses

Some of the common types of viruses include:

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.

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.

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.

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.

Overwriting Virus: Copies its own code over the host computer system’s file data, which destroys the original program.

Cluster Virus: This virus links itself with the execution of programs by altering directory table entries in order to ensure that the virus itself will start when any program on the computer system is started. If infected by this virus, it will look as if all programs on your PC are infected; however, this virus is just in one place on the system.

Virus Protection vs Virus Removal

Virus protection software or antivirus software has been designed mainly to prevent infection, however, this software can also remove malware from an infected computer. Stand-alone system virus removal software or a malware remover provides a suitable way to find and remove malware from a computer in case the product already installed fails to do so.

Key difference between virus protection and virus removal software

Virus protection software is all about prevention as it is used to prevent files containing viruses from being downloaded onto your computer. It also prevents the virus from being activated if it somehow gets downloaded to your computer, placed in a file-like location or in memory. If the file is downloaded, but flagged by antivirus software as malware and prevented from being activated, it will cause any damage to your system even though the infected file will still need to be contained and deleted.

Assume a situation in which an infected file is downloaded and then run, making the virus active. This is usually done by accident, for instance, by opening a virus-infected file attachment in an email or clicking a malicious URL link.

Virus protection software may sometimes have rudimentary tools to remove active viruses, but modern malware is considered to be sophisticated in hiding on the infected computer where it can be re-initiated at a later time, hence these rudimentary tools may not completely remove infections.
System virus removal software provides tools that are used to specifically take malware out from an infected computer if a virus manages to pass through an antivirus software check. Malware here includes contained viruses, active viruses, and inactive malware that could be hidden and lurking on the infected computer.

Virus Removal from Your PC

If your PC does have a virus, adopt the following actions:

Remove the virus

Step 1: Enter Safe Mode

Turn your computer off and on again. Press the F8 button repeatedly as soon as you see anything on the screen. This brings up the Advanced Boot Options menu. Choose Safe Mode with Networking and press Enter. Keep your PC disconnected from the Internet.

Step 2: Delete Temporary Files

While in Safe Mode, you should delete your Temporary Files using the Disk Cleanup tool:

  • Go to the Start menu
  • All Programs (or just Programs)
  • Accessories
  • System Tools
  • Disk Cleanup
  • Scroll through the Files To Delete list, and then choose Temporary Files

Deleting these files could speed up the virus scanning you are about to do and could even help to get rid of a virus if it was programmed to start when your computer boots up.

Step 3: Download a Virus Scanner

Step 4: Run a Virus Scan

Recover or reinstall any damaged files or software

Assuming the scan identified and removed the virus, you may have to reinstall any files or programs that were damaged by the virus. This is where backups become useful, and you should make them regularly.

Improve your defences

Keep your protection up to date

Updating your virus protection software will help protect your PC against viruses and malware. Keeping it up to date is essential because new viruses are being developed all the time, hence even if you bought your antivirus a month ago, it could need immediate updating.

Make backups

Ensure to make regular backups of your files and store them on an external hard drive. This will help prevent the loss of vital information should you get another virus.

Take proactive measures to prevent getting another virus attack

Some quick things that will help in preventing you from downloading a virus again:

  • Install an antivirus program
  • Regularly back up your data
  • Install the latest software updates for Windows
  • Avoid clicking on pop-up messages that claim to have detected an issue with your computer
  • Be cautious of opening emails from addresses you do not recognize, particularly if they contain an attachment or a link

What is Data Security?

data security

The terminology “Data security” refers to the protective measures of securing data from unapproved access and data corruption throughout the data lifecycle. Today, data security is an important aspect of IT companies of every size and type. In the process, they deploy data security solutions which include tokenization, data encryption, and key management practices that protect data.

Data security is also known as System Data Security, Information Security or Computer security.

Why Data Security Solutions?

Data is an important asset to any organization and thereby, it is essential to safeguard it from online criminals. Organizations across the globe are investing heavily in information technology (IT) to deploy the best of cyber defense capabilities.

Basically, organizations are focused on protecting three common elements namely people, processes, and technology. This inwardly protects intellectual capital, critical infrastructure, customer information, brand and much more. Data security is not just important for organizations. Data protection comes into play on the personal computer, tablet, and mobile devices which could be the next target of cybercriminals.

Normally, remote devices that connect with an organization get targeted by attackers to tap the sensitive information. This is were the endpoint protection, endpoint security comes into play, it helps to protect and maintain the devices connecting the network.

Data breaches and cyber-attacks are anticipated to increase in the due course of time as the computer networks expand. It is important to have the right Data Security Solutions in place to meet the challenging threats.

Types of Data Security and their Importance

Data security software protects a computer/network from online threats when connected to the internet. The data security software may also protect other areas such as programs or operating-system for an entire application. Its goal is to recognize rules and actions to apply against strikes on internet security. There are several types of security, and they are:

Network Layer Security

The cryptographic techniques also protect TCP/IP (Internet protocol) alongside other internet protocols that have been designed for protecting emails on the internet. The techniques include SSL and TLS for the traffic of the website, PGP for email and for network security its backed by IPSec.

IPSec Protocol

The IPSec Protocol was initially developed for guarding interaction using TCP/IP. It was designed by the IETF, and it provides security and verification by using the method of cryptography, the data is modified using security methods. The two main aspects of modification that form the reasons for IPSec are Authentication Header (AH) and Encapsulating Security Payload (ESP).

Email Security

The protective measures employed to safeguard the access and content of an email account or service is called Email Security. Basically, the electronic mail is composed, saved, and delivered in multiple step-by-step procedures that start with the message’s structure. An email security software is implemented by the service provider to secure subscriber email accounts and data from hackers.

Data Security vs. System Security

Data security refers to the efforts that an organization takes to guarantee that the information stored isn’t deliberately accessed or accidentally deleted or modified, manipulated or otherwise abused for illegal money-making. System security works closely associating with data security. System security protects everything that an organization wants to ensure in its networks and resources. Simply put, data security is meant to protect the information and system security is what protects the information containing the devices and network. Comodo offers one of the best 360 degree protection for data and resources.

Lets quickly go through some of the common techniques of cyber attacks. Know how your organization can mitigate these risks.

Backdoor Attack – Not all the computer networks are secure as they seem. Seldom programmers leave codes open that enable the troublemakers to access a network completely. As a matter of fact, cybercriminals look for such exploits and make use of the weak points. Always be vigilant to review the code for any customized software used on your organization and that software-as-a-service and platform-as-a-service suppliers are not vulnerable to these kinds of attacks.

Denial of Service (DoS) Attack- Instead of sneaking into a computer network to loot valuable data, malicious people may try overpowering the network by trafficking it with loads of requests for service, slowing access and network-reliant operations to a crawl. A usual denial of service attack can be stopped by blocking the attacker’s IP address. However, a more complicated attack type, distributed denial of service (DDoS) attack, is difficult to hold, as it includes numerous IP addresses. But, today many vendors market solutions that decrease the effects of DDoS attacks.

Direct Access Attack- People accessing physical assets in your organization would easily access your most confidential information. Fraudsters who desperately want to lift the data can easily steal hard drives, flash drives, and laptops or break into your office, and copy the information they want. Thereby, it is safer to heighten security by providing employee training, and information encryption.

Malware Attack- Malicious software/malware attack are very common these days. An intruder gains access to the computer network and then encrypts all the valuable data without a trace. In order to access your data, you need to get the encryption key, and you must pay a ransom. The payments are made through bitcoin and there are possibilities that the ransom escalates in price over time. Malicious programs sneak into your system or network through a virus or worm, so instruct the employees about the online threat of clicking on suspicious linkings or opening unknown attachments.
