I-Worm.Heffer Removal Guide

What is I-Worm.Heffer?

Heffer – a computer worm that spreads automatically

I-Worm.Heffer

Worm Heffer spreads on the Internet by e-mail messages with infected executable attachments, although users might also infect their PCs after inserting a removable drive containing the malicious payload. Once installed, the worm spreads all over the computer, infecting many core system and application files.

Name Worm Heffer
Type Worm, malware
Function Infects multiple Windows system and application files, terminates processes of some security programs
Dangers Installation of other malicious programs, information leak, other computer infections
Elimination Use anti-malware software (access Safe Mode if required)
System fix ReimageIntego can help you fix virus damage effectively

Since removable drives are the main distribution vector of the worm, disabling the autorun function could stop the worm from accessing your computer. However, users never know if the drive is infected in the first place, allowing it spread freely. A robust anti-malware program can stop the malicious payload from being delivered to the computer. We strongly recommend using SpyHunter 5Combo Cleaner or Malwarebytes for the Worm Heffer removal process.

On the infected computer, it modifies popular chat programs mIRC and KaZaA peer-to-peer application and spreads through them also. Once per month, it displays several message windows.

The worm can infect some text documents and terminate most processes of antivirus and security-related programs, which can make the elimination process rather difficult. This tactic is often used by malicious programs in order to increase threat persistence.

However, the most up-to-date security software should not be affected by this malware trait. If it is, simply reload your computer in Safe Mode. If you are not sure how to reach it, follow the instructions we provide below. Also, if you notice that your Windows is malfunctioning after you delete the worm, system files were likely compromised. To revert this damage, we strongly recommend using ReimageIntego.

Delete the worm and stop the Autorun for better protection

Removable drives are rarely used for malware distribution nowadays, but that does not mean that it does not happen. In order to protect yourself from such an infection method, you should firstly install a powerful anti-malware software which likely to detect and stop the payload before it is executed.

Also, disabling the Autorun function can stop the parasite from spreading. Here's how:

  • Right-click on Start and select Settings
  • Go to Devices section
  • Select AutoPlay on the left side
  • Turn the switch to the left to turn the feature off.

How to prevent from getting worms

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
