What is WebHelper process? Is WebHelper a virus or is it legitimate file? Why WebHelper is running at 100% CPU?
The WebHelper malicious threat is a widespread virus that is being spread across the Internet using various methods. While it is not by itself a dangerous application there are many solitary fles which contain various types of viruses. As such careful attention should be paid to all users that encounter such files.
The malware files can be acquired through various methods. The hackers may send out phishing email messages or create hacker-made malware sites that are hosted on similar sounding domain names to well-known Internet pages. They can include stolen or fake content, multimedia elements hijacked from real sites and self-signed or stolen security certificates.
To facilitate a larger number of infected users the criminals behind the WebHelper .exe malware can embed the virus installation code into payload carriers of various types. This includes all sorts of documents across the most popular file formats: spreadsheets, presentations, text files and databases. They are to be infected with the necessary scripts (macros) that will download and run the built-in malware as soon as they are launched. The other mechanism is the creation of malicious installers of popular software which are often used by end users.
These files can be uploaded file-sharing networks like BitTorrent where both legitimate and pirate data is freely distributed. When the hackers want to infect a larger number of users they can make browser hijackers — malware plugins made compatible with the most popular web browsers which are commonly uploaded to their repositories with fake user reviews and developer credentials.

Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
IMPORTANT! Before starting “Step 4”, please boot back into Normal mode, in case you are currently in Safe Mode. This will enable you to install and use SpyHunter 5 successfully.
Step 4: Scan for WebHelper with SpyHunter Anti-Malware Tool

If any threats have been removed, it is highly recommended to restart your PC.
Step 5 (Optional): Try to Restore Files Encrypted by WebHelper.
Ransomware infections and WebHelper aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
