How to remove the Weekly Stock Loader adware-type browser extension
Written by Tomas Meskauskas on
What is Weekly Stock Loader?
While checking out deceptive sites, we discovered the Weekly Stock Loader browser extension. It is promoted as a tool that provides weekly information about users' favorite stocks. However, our analysis of Weekly Stock Loader revealed that it operates as advertising-supported software (adware).
Weekly Stock Loader adware overview
Adware is designed to run intrusive advertisement campaigns, i.e., display ads on visited websites and/or different interfaces. The adverts endorse various scams (e.g., phishing, tech support, giveaway, etc.), untrustworthy/harmful software (e.g., adware, browser hijackers, etc.), and malware (e.g., trojans, ransomware, etc.).
Furthermore, some intrusive advertisements are capable of performing stealthy downloads/installations upon being clicked.
It is pertinent to mention that any genuine content encountered through these ads is most likely promoted by scammers who abuse its affiliate programs in order to acquire illegitimate commissions.
Advertising-supported software might not deliver advertisements if certain conditions are unsuitable, e.g., incompatible browser/system specs or user geolocation, particular websites not visited, etc. However, even if Weekly Stock Loader does not display adverts – its presence on a system endangers device/user safety.
What is more, this rogue browser extension spies on users' browsing activity. Targeted data may include: visited URLs, viewed webpages, searched queries, personally identifiable details, account log-in credentials (usernames/passwords), credit card numbers, etc. The collected information can be sold to third-parties or otherwise abused for profit.
To summarize, the presence of software like Weekly Stock Loader on devices can result in system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples
We have inspected thousands of adware-type apps and browser extensions; Loading Timer, Download Checker, and Duplicatefinder are merely a couple of examples.
Advertising-supported software tends to appear legitimate and advantageous. Users are enticed into download/installation with a wide variety of useful features. However, these functionalities seldom work as promised, and in most cases – they are utterly nonoperational. Keep in mind that software functionality is not proof of either legitimacy or safety.
How did Weekly Stock Loader install on my computer?
We obtained Weekly Stock Loader from its "official" download webpage and found a deceptive site pushing this browser extension. Users typically access pages of this kind via redirects caused by misspelled URLs, websites using rogue advertising networks, spam browser notifications, intrusive ads, or adware (with browser force-opening abilities).
Additionally, intrusive advertisements can infiltrate advertising-supported software into systems. When clicked on, some of the adverts can execute scripts to perform downloads/installations without user consent.
"Bundling" – packing regular program installers with unwanted/malicious supplements – is used to proliferate adware. Downloading from dubious channels (e.g., freeware and free file-hosting sites, Peer-to-Peer sharing networks, etc.) and rushing through installation processes (e.g., using "Easy/Express" settings, etc.) – increase the risk of unintentionally allowing bundled content into the system.
How to avoid installation of adware?
We strongly recommend researching software prior to download/installation. Furthermore, all downloads must be performed from official and verified sources. Installation must be treated with caution, e.g., by reading terms, inspecting available options, using "Custom" or "Advanced" settings, and opting-out of additional apps, extensions, etc.
We advise being careful when browsing since fraudulent and malicious content usually appears legitimate/innocuous. For example, intrusive advertisements may look harmless yet redirect to unreliable/questionable websites (e.g., pornography, adult-dating, gambling, etc.).
In case of encounters with such ads and/or redirects, inspect the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Weekly Stock Loader, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
