How to remove ValidVersion.app from systems

What kind of application is ValidVersion.app?

We have tested ValidVersion.app and found that it is adware associated with the Pirrit family, and multiple security vendors classify it as malicious. Once installed, it may display intrusive and misleading ads that can lead users to untrustworthy websites. For this reason, ValidVersion.app should be removed if it is found on a device.

ValidVersion.app adware in detail

Because ValidVersion.app is flagged as malicious, it may show deceptive alerts, promotions, and other ads through pop-ups, banners, coupons, and similar formats. These ads can be crafted to take users to unreliable websites or execute scripts that may cause unwanted or unexpected downloads.

Clicking on these ads can lead users to websites crafted to collect sensitive data, such as login details (usernames and passwords), financial information like credit card numbers, and other personal data. Users may also be directed to pages promoting fraudulent products, fake services, bogus giveaways, or similar schemes, and sites that distribute potentially malicious software.

In addition, ValidVersion.app may gather browsing-related data, such as search queries, IP addresses, and visited websites. It can also collect personal information, including usernames and email addresses, and in some cases, sensitive details like login credentials, banking information, and other private data.

In some cases, adware can act as a browser hijacker. This happens when an unwanted program alters the default search engine, homepage, or new tab settings. As a result, users may be forced to land on fake search engines or other untrustworthy websites instead of the pages they intended to visit.

Finally, manually removing ValidVersion.app can be challenging because it may use persistence mechanisms to prevent removal. If that happens, using a security tool such as Combo Cleaner to perform a full scan can help detect and eliminate the adware.

Conclusion

Overall, ValidVersion.app poses risks due to its ability to display misleading ads and potential redirects to unsafe websites. It can also compromise user privacy by collecting information, which may be misused for malicious purposes. For these reasons, it is important to remove the application if it has been installed.

More adware examples are EngineTrack, DailyHandler, BalanceOptimizer.

How did ValidVersion.app install on my computer?

Adware is often included alongside free or low-quality software. It can be installed unintentionally when users rush through the setup process and accept the default settings instead of choosing "Custom", "Advanced", or similar settings where they can reject unwanted apps.

It may also be distributed through misleading advertisements, pop-ups, or similar content on untrustworthy websites. Additionally, downloading software or files from unofficial sources, such as third-party app stores, download managers, or peer-to-peer (P2P) networks, can result in adware being installed.

How to avoid installation of unwanted applications?

Always keep your operating system and installed applications up to date, and regularly use trusted security software to run system scans. When downloading programs, use only from official sources or reputable app stores, and carefully review each step to decline any unnecessary or optional components during installation.

Exercise caution while browsing, particularly on questionable websites - avoid clicking on suspicious links, pop-ups, or advertisements, and do not grant notification permissions to unfamiliar or untrustworthy sites. If your computer is already infected with ValidVersion.app, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
