Malware are malicious programs wrapped up in genuine programs, which are coded with the intent to cause harm to a computer or a network. To combat the increasing cyber threats in an enterprise, you will need to have a good understanding on malware removal, different types, and their spreading methods. Below is a glimpse at the basic details of malware that would help you in dealing with the issue.

Malware Terminologies

Drive-By Download

These programs spread by the unintended download of computer programs from the internet. Drive-by download either refers to the download that happens without the knowledge of the user, or that authorized by the user without the knowledge on the outcomes.

Vulnerability

Vulnerability refers to a security defect in software that can be exploited by the malware. The defect can be a flaw in design, error in programming, or some other inherent weakness in the implementation of the software or operating system.

Homogeneity

Homogeneity is a setup where all the systems in a network are running on the same operating system. Homogeneity increases the chance of a malware in one PC spreading to the other in the same network.

Backdoor

Backdoor refers to a break or an opening left in a software, system or network security by design. Backdoors are mainly used for debugging purposes.

Malware Attack Methods

Zero-Day

A zero day vulnerability refers to an undisclosed flaw that the developers of malwares can exploit. These vulnerabilities are called Zero-Day, as they are not announced or reported to the public before they become active.

Privilege Escalation

Privilege escalation refers to situations where the hacker gets access to restricted data that are on high-level security.

Exploit

Exploit refers to a threat that is made real through successful attacks on vulnerability. The term exploit is also used to refer to software that is developed with the aim to target on the loopholes on a device.

Blended Threat

This term is used to refer to a malware package that combines the characteristics of different types of malware like worms, Trojans, or viruses and seeks to exploit multiple vulnerabilities in the system.

Evasion

Evasion is the technique that malware developers use to avoid analysis and detection of the malware by security programs and software.

These are the various ways in which malware programs attacks a system. It can be difficult or easy to get rid of a malware attack based on the severity of the attack. If you suspect a malware attack on your system, you will need to contact a computer virus removal technician for help with malware removal.

When the code in a file is altered, it becomes corrupted. The corruption can be caused due to many reasons. For that reason, you need to know how to fix corrupted files if you want to run the program in which the corrupted file is.

It is rather annoying to have error messages pop up every time you try to run the program. Even folders can become corrupted the same way. So, here is how to fix corrupted files and folders by reinstalling or replacing them.

Spot The Corrupt File

If one of your programs has stopped working all of a sudden, you need to find out which corrupt file is causing the problem. However, the only way to find it is when an error message appears. The message may say something like ‘filename.abc is corrupt’. Note down the name of the file as the error message pops up.

Locate It

Next, you need to locate the specific file. Open the Start Menu and click on the Search button. In the window that pops up, enter the name of the corrupted file. Search for it in the entire computer. You may choose to search for hidden and archived folders too. Press on the Enter button and your computer will start searching for it.

Rename It

Rename the file that you just found. You may choose to rename it from the Search box itself or by opening the folder in which it is located. If you do not see the Rename option in the right-click context menu, click on the File button in the main toolbar and select the Rename option from there. You need to rename the file with something similar to what it was named before. This will help you locate it if needed in the future.

Reinstall It

The only way to reinstall the corrupted file is by reinstalling the program in which the error message popped up. Since you have renamed the corrupt file already, that specific file will be considered as ‘missing’ during reinstallation. Hence, only this specific file will be reinstalled.

Replace It

If you do not have the installation software of the program, you may look for the proper version of that file online. For this, open any search engine’s page and enter the name of the corrupt file. You will see a list of websites having a copy of the specific file available for download.

If none of these steps work, go the program developer’s page and look for an update of the program or a downloadable version of the corrupt file.
