Valerie adware removal instructions
What is Valerie?
Valerie is a rogue application classified as adware. Following successful infiltration, it runs intrusive advertisement campaigns. I.e., Valerie delivers various misleading and even harmful ads. Most adware-type programs have data tracking capabilities, which are used to gather browsing related information. It is likely that Valerie possesses this functionality as well. Due to the dubious methods used to proliferate adware-type apps, they are also classified as Potentially Unwanted Applications (PUAs).
Adware enables the placement of third party graphical content, typically on any visited website. Therefore, the pop-ups, banners, coupons, surveys, full-page and other intrusive ads do not originate from the original websites. The delivered advertisements significantly diminish the browsing experience, as they overlay web page content and reduce browsing speed. Furthermore, once clicked, intrusive ads can redirect to various untrusted/malicious websites and some can even stealthily download/install software. PUAs are a prime example of content infiltrated into systems in this manner. These unwanted applications have dangerous capabilities and these functions can be in varied combinations. Some PUAs can force-open dubious and dangerous sites. Browser hijackers are another type of PUA, which operate by making modifications to browser settings and restricting/denying access to them to promote fake search engines. The promoted search engines are seldom able to provide search results, and so they tend to redirect to (or cause redirection chains) ending with Google, Yahoo, Bing and other legitimate sites. Furthermore, most PUAs (including adware) can track data. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered data is then monetized by sharing with and/or selling to third parties (potentially, cyber criminals). In summary, the presence of unwanted software on devices can result in system infections, serious privacy issues, financial loss and even identity theft. To ensure device integrity and user safety, all suspicious applications and browser extensions/plug-ins must be removed without delay.

Valerie is practically identical to MusiCalm, and shares many similarities with WikiNow, RelevantKnowledge, PopBlock+, Giphy Search and countless other adware-type apps. They may seem legitimate and offer a broad range of "useful" functionality, however, despite how good the features promised may sound, they are usually nonoperational. In fact, this applies to most PUAs. The only purpose of this unwanted software is to generate profit for the developers. Rather than delivering any real value, PUAs run intrusive ad campaigns, cause redirects, hijack browsers and collect private data.
How did Valerie install on my computer?
PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling". By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well. When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.
How to avoid installation of potentially unwanted applications
You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided. When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others). If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with Valerie, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
