Security research indicates that a Google Chrome extension called JumboSale has appeared troublesome. According to users, once installed, the extension generates unwanted pop-up windows that can be intrusive. The pop-ups are reported to provide fake system alerts regarding software updates, and suggesting the user to call a phone number. Users may be redirected to a fake Java site to download fake updates. Executing such updates is not safe and may compromise the computer’s performance.
Thus, JumboSale may be considered a fake tech support scam. Moreover, the extension may not be found in the list of the browser’s official extensions. If detected on the system, the removal of JumboSale is a priority.
→N.B. Even though the extension was detected on Google Chrome, it may still be compatible with other browsers such as Mozilla Firefox and Internet Explorer.
JumboSale Distribution across the Web
The application may have been downloaded together with a free program downloaded from the Web. This is known as software bundling – a term popular in marketing and adopted by third party developers and advertisers. Basically, bundling applies to the process of selling several products as one.
Also, the user may have triggered it by downloading a fake update or landing on a suspicious website.
JumboSale Extension Removal Steps
The extension may ‘reload’ each time the browser is started. Thus, inexperienced users may not be able to remove it manually by following instructions. However, manual removal can still be tried. There are several steps provided below the article. If it doesn’t work, running AV software to scan the system is advisory.
For the sake of future’s safety, being careful while downloading freeware is advisory. Executing Java, Adobe, etc, updates that are presented as pop-up windows is also considered risky.
