Win Tonic Unwanted Application

Also Known As: Win Tonic potentially unwanted program
Damage level: Medium

What is Win Tonic?

Win Tonic is presented as an application that helps to remove various infections and optimize the system.

Initially, Win Tonic may appear completely appropriate, however, developers promote this potentially unwanted program (PUP) using fake error messages such as Your Windows Computer Is Infected With (4) Viruses! and scam pop-ups. For these reasons, Win Tonic is classed as a potentially unwanted program (PUP).

Win Tonic unwanted application

Win Tonic provides functionality allowing users to perform a full system scan. They are prompted with a list containing hundreds of potential infections/threats and are encouraged to immediately remove them, however, since Win Tonic's 'free version' is not capable of this function, users are encouraged to pay for the 'full version'.

The problem is that it is currently unconfirmed whether Win Tonic is actually legitimate. The list of infections might be false and your computer might be optimized and virus-free. In such case Win Tonic would not give any real value for regular users - it would simply clear the list of threats. In other words, developers attempt to generate revenue by abusing users' trust.

If you've been tricked into installing Win Tonic by some sort of online scan performed by a website, you should uninstall this application. If, however, you've installed Win Tonic intentionally, we advise you to reconsider this application and install another reputable anti-virus/anti-spyware suite instead.

As mentioned above, Win Tonic typically infiltrates systems without permission and, thus, will probably have been delivered with a number of other PUPs.

These programs typically do three things: 1) deliver intrusive online advertisements [adware]; 2) modify web browser options [browser hijackers], and; 3) record sensitive information [all types]. These programs are useless and should be uninstalled immediately.

There are many potentially unwanted programs similar to Win Tonic. For example, PC Accelerator, Free Malware Removal Tool, PCMax, and Advanced PC Care.

All claim to provide 'useful functionality', however, these claims are merely attempts to give the impression of legitimacy and trick users to install. PUPs such as Win Tonic are designed only to help developers generate passive revenue.

Rather than enabling the functionality promised, PUPs deliver intrusive ads ("Pay Per Click" advertising model), cause unwanted redirects (modification of browser options), gather sensitive information (information selling), and, in this case, promote in-app purchases. Potentially unwanted programs pose a direct threat to users' privacy and Internet browsing safety.

How did Win Tonic install on my computer?

As mentioned above, Win Tonic is promoted via fake errors, which claim that the system is damaged and offer to download a 'repair tool'. Due to the lack of knowledge and careless behavior of many users, Win Tonic is likely to infiltrate systems without users' consent. Potentially unwanted programs are often distributed using intrusive advertising and "bundling" methods.

Intrusive ads redirect to malicious websites and execute scripts that stealthily download and install malware/PUPs, whilst "Bundling" is stealth installation of PUPs with regular software.

Developers hide "bundled" apps within "Custom/Advanced" settings or other sections of the download/installation processes. Many users click advertisements and skip download/installation steps. This behavior often leads to inadvertent installation of various PUPs such as Win Tonic.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet and, especially when downloading/installing software. Bear in mind that criminals invest many resources into intrusive ad design, thereby making them seem legitimate.

These ads redirect to gambling, adult dating, pornography, and other dubious websites. Most intrusive ads are delivered by adware-type PUPs - if you encounter them, immediately remove all dubious applications and browser plug-ins.

Furthermore, select the "Custom/Advanced" settings, carefully analyze each step of the download/installation processes, and opt-out of all additionally-included programs. You are advised to download your software from official/trusted sources only, using direct download links.

Third party downloaders/installers are often monetized using the "bundling" method (promoting PUPs), and thus these tools should never be used.
