How to remove Best Converter Online adware and the adverts it delivers
Written by Tomas Meskauskas on (updated)
What is Best Converter Online?
During a routine inspection of untrustworthy websites, our researchers discovered the Best Converter Online browser extension. It is promoted as a tool for easy file format conversion. After analyzing it, we determined that it is a piece of advertising-supported software (adware).
Best Converter Online adware overview
Best Converter Online began running intrusive advertisement campaigns (i.e., delivering various adverts) following successful installation onto our test machine. It is noteworthy that adware may require certain specifications to operate as intended (e.g., compatible browser/system or user geolocation, visits to particular sites, etc.). However, regardless of whether Best Converter Online displays ads or not - its presence on a device endangers device/user safety.
Adware-delivered advertisements endorse untrustworthy/harmful websites and software, online scams, and even malware. Furthermore, some intrusive adverts can infiltrate software into systems - when clicked on.
It is pertinent to mention that reputable developers are highly unlikely to use this marketing method to promote their products, yet they can be encountered through these ads. However, scammers who abuse affiliate programs commonly use this advertising to obtain illegitimate commissions.
Best Converter Online also uses data tracking abilities. Advertising-supported software typically targets browsing activity (e.g., visited URLs, viewed webpages, searched queries, etc.), personally identifiable details, account log-in credentials, financial/banking information, and so on. The gathered data is then shared with and/or sold to third-parties.
In summary, the presence of Best Converter Online or other adware on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples
PDFEditor, Power Off, Page Darker, and Buyers Assistant are a few examples of the adware-type apps and browser extensions we have analyzed. This software usually appears legitimate and offers "handy" features, which are seldom operational. Therefore, adware is not only useless, but it also endangers device integrity and user privacy.
How did Best Converter Online install on my computer?
We have obtained Best Converter Online from its "official" promotional/download webpage. Sites of this kind can be accessed via mistyped URLs or redirects caused by pages that use rogue advertising networks, spam browser notifications, intrusive advertisements, or installed adware (with browser force-opening capabilities).
"Bundling" - packing regular programs with unwanted/malicious additions - is also used to proliferate advertising-supported software. Download from dubious sources (e.g., Peer-to-Peer sharing networks, unofficial and freeware websites, etc.) and rushed installations - increase the risk of allowing bundled content into the device.
Additionally, once clicked on, some intrusive ads can execute scripts to stealthily download/install adware and other untrustworthy software.
How to avoid installation of adware?
We highly recommend researching software and only downloading from official and verified channels. Additionally, it is important to exercise caution when browsing, which includes - reading terms, studying possible options, using the "Custom/Advanced" settings, and opting-out of all additions.
We also advise being vigilant when browsing, as illegitimate and malicious content usually appears harmless. For example, intrusive adverts look legitimate yet redirect to unreliable and questionable sites (e.g., gambling, pornography, adult-dating, etc.).
If you experience such advertisements/redirects, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Best Converter Online, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
