removal by Gabriel E. Hall - - | Type: Malware

YahLover.worm pop-up is a bogus alert that tries to make users spend money on fake tech support services

YahLover.worm fake alert

YahLover.worm is a non-existent virus name that malicious actors came up with to use in a scam scheme. The fraudulent pop-up might show up on Google Chrome, Mozilla Firefox, Safari, or another web browser unexpectedly. In the background, users will also see a seemingly legitimate Google-type browser waning that alerts about malware or phishing danger. In the meantime, the alert will inform you that the computer was infected with a YahLover.worm virus and that a personal information leak is almost inevitable.

However, YahLover.worm virus pop-up is a tech support scam[1] that should never be trusted, as the message is simply a web page shown within the browser. Once the provided number is called, threat actors will attempt to extort money from victims in various ways or infect their machines with keylogging or other info-stealing malware.

While you can encounter YahLover.worm notification on a random website by accident, frequent appearances of bogus websites and ads might indicate adware infection on Mac or another operating system. When such an infection infiltrates the system, it hijacks the web browser and starts causing fake alerts.

Similarly to You Have A ZEUS Virus scamWindows Detected ZEUS Virus scam or Windows Defender Alert: Zeus Virus, this infection scam seeks to scare you into thinking that your computer is infected with the banking virus and that the only way to fix it is to dial a special number and reach for some “reputable” technicians. In reality, the only ones that you can reach are scammers.

Pop-up window titles of such fake alerts vary. However, the most popular of them are RDN/YahLover.worm!055BCCAC9FEC infection and rdn/yahlover.worm 055bccac9fec infection notifications. They both suggest dialing 1-844-592-9882, 1-800-214-7440, or similar numbers to get technical help.[2]

On the one hand, the felons did a good job by forging a legitimate browser‘s alert. Interestingly, that phone number varies each time, which suggests the scale of this scam.

What is more, the scam may prevent you from leaving this page. However, you can cancel it by choosing “Prevent this page from creating additional dialogues.” After that, we highly recommend you to remove YahLover.worm fake alert and programs (malware) which are related to it.

Despite its name, which falsely claims to be a computer worm, the notification has nothing to do with malware infection (although adware is sometimes considered malicious by some security researchers). Therefore, YahLover.worm removal is not necessary, as such a virus simply does not exist. What is necessary tho is terminating adware from the computer as we explain below, resetting the installed web browsers, and then using ReimageIntego to fix potential damage done to the system.

YahLover.worm virusYahLover.worm urges victims to call the number ASAP.

Recently, tech support scams have become more active than ever[3] and there is no surprise why. In the age of informational technologies, personal data has become one of the most valued things. The idea of losing it may seem more terrifying than the fact itself. Likewise, such sentiments are the perfect inspiration resource for crooks.

The creators of YahLover.worm have been trying to scare netizens with a virus infecting their systems and stealing personal information.[4] If you are one of their victims, you should notice such misleading alert on your Safari or other web browser:

RDN/YahLover.worm!055BCCAC9FEC Infection
Call Technical Support Immediately at 1-800-214-7440
The following data will be compromised if you continue:
1. Passwords
2. Browser History
3. Credit Card Information
This virus is well known for complete identity and credit card theft. Further action through this computer or any computer on the network will reveal private information and involve serious risks.
Call Technical Support Immediately at 1-800-214-7440

Less proficient computer users might be horrified with such a message and dash off to call the number given in the report. In this case, you can be tricked into losing hundreds of dollars for supposed tech support.

Once the scammer notices that the victim is inexperienced PC user, he/she usually tries to connect to the system remotely and shows the alleged competence by launching Command Prompt or Powershell. Users might fall into such a scam and transfer the money for the supposed technical assistance.

While some scammers remove the “virus” to withdraw pop-up from the computer, other felons leave a “farewell gift” – ransomware or another virus. In this relation, YahLover.worm infection scam may not behave so aggressively, but its presence should not be ignored.

The distribution peculiarities of this tech support scam

The majority of tech support scams are spread via corrupted websites and poorly protected web pages. Likewise, if you tend to download programs and use services promoted in pirated domains, you might be redirected to the website monitored by the scammers, and then, enjoy the unpleasant effects of adware hijack.

Luckily, this adware does not possess a sophisticated technical structure, so it will not be difficult to deal with it. However, its termination process will require your attention.

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
