How to get rid of the Multiple Account adware-type browser extension
Written by Tomas Meskauskas on (updated)
What is Multiple Account?
Multiple Account is the name of a rogue browser extension promoted as a tool that can save and import Internet cookies from other accounts. After analyzing this piece of software, we determined that it operates as adware.
Multiple Account adware overview
Adware stands for advertising-supported software. It is designed to run intrusive advertisement campaigns.
Multiple Account operates by force-opening various websites. It can cause redirects to the following types: questionable (e.g., adult-dating, pornography, gambling, etc.), scam-promoting (e.g., phishing, fake virus warning, bogus giveaway, etc.), software-endorsing (e.g., adware, browser hijacker, fake anti-virus, PUA, etc.), malware-proliferating (e.g., trojan, ransomware, etc.), and other suspicious/dangerous sites.
Furthermore, adware usually collects private information, and this is likely true of Multiple Account. Targeted data may include: visited URLs, viewed webpages, searched queries, usernames/passwords, personally identifiable details, finance-related information, etc. The gathered data can be shared with and/or sold to third-parties.
To summarize, the presence of software like Multiple Account on devices can result in system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples
Text to Google Maps, border colors, Chromnius, and Motivational Quotes are merely some examples of adware that we have analyzed recently. Advertising-supported software usually appears legitimate and innocuous. It offers a wide variety of "handy" and "advantageous" functionalities. However, these functions are rarely operational.
How did Multiple Account install on my computer?
Multiple Account was installed onto our test machine by a malicious installer. Adware is often disguised as or bundled with ordinary content.
"Bundling" is a marketing technique that entails pre-packing regular program installation setups with unwanted/malicious additions. Downloading from dubious sources (e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc.) and rushing installations (e.g., using "Easy/Quick" settings, etc.) increase the risk of allowing bundled content into the device.
Intrusive advertisements proliferate adware as well. Once clicked on, some of the ads can execute scripts to make downloads/installations without user consent.
Advertising-supported software can also have "official" promotional sites, and it is endorsed on scam webpages. Most users enter these websites via redirects caused by pages using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive adverts, or installed adware (including browser force-opening abilities).
How to avoid installation of adware?
We strongly recommend downloading only from official and verified channels. Additionally, when installing, it is essential to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out of all supplementary apps, extensions, tools, etc.
We advise being careful when browsing since illegitimate and malicious material usually appears ordinary and harmless.
Should you experience the previously described ads/redirects, check the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Multiple Account, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
