Ie3wisa4 is a deceptive domain that used to display Android and computer users intrusive ads and redirect them to dubious sites
Ie3wisa4 is a redirect virus that users might encounter on their Android devices, desktop computers, as well as Macs when browsing the internet. The domain is often used by potentially unwanted programs like adware[1] to redirect users to unknown sites that push pop-ups, deals, offers, banners, hyperlinks, and other sponsored content.
The intrusive advertisement content can appear on various browsers, such as Google Chrome, Internet Explorer, Safari, Mozilla Firefox, Opera, and others. Nevertheless, the activity of Ie3wisa4.com can be isolated to a particular browser or affect all the installed ones.
Ie3wisa4 virus behavior depends on the type of adware that is installed; for example, if the unwanted ads are only prevalent in one of the browsers, it is highly likely that the culprit is browser plugin or extension. In contrary, the widespread operation means that adware application is installed on the computer. In such a case, to remove Ie3wisa4.com redirects, users will have to uninstall the app that is causing the unwanted activity.

Adware, initially regarded as “spyware,” managed to get a “not-a-virus”[2] title over the years and labeled as potentially unwanted. However, the growing concerns over the safety of such software from security community served as a wake-up call: ads served by adware are not always safe, and users might compromise their online safety when they get redirected to domains like Ie3wisa4.com.
Besides seeing intrusive ads, Ie3wisa4.com redirects can also bring users to spoofing,[3] phishing and tech support scam sites, which will try to mislead people either installing bogus software like Advanced Mac Cleaner or paying for bogus tech support services. Consequently, users can lose a large amount of money or end up installing other PUPs that might even harm their devices.
Finally, the presence of Ie3wisa4 also means that unknown parties are tracking your online activities, and the following data is harvested:
- IP address
- Geolocation
- Search terms
- Sites visited
- Links clicked
- Duration of the visit
- Technical data, etc.
While this information does not identify you personally, you should not allow third-parties to scrutinize your online behavior, as it might bring to privacy issues.
You should proceed with Ie3wisa4 removal either by using security software or our manual guide below.
Adware can be downloaded intentionally, although it usually travels within software bundles
Adware is a sneaky type of software that usually gets installed together with other free programs from the internet, such as media players, file converters, download managers, browser extensions, etc. This happens because developers of freeware and shareware strike a deal with adware authors and bundle programs in one installer package. For every additional install, developers of free programs receive payments, so it is in their best interest to make as many users as possible to install unwanted applications.
However, you don't need to be a PC expert to avoid such installations. All you have to do is pay more attention when installing new software. First of all, you should always make sure that it is coming from a reputable source and never download software from torrent and similar sites. Also, during the installation process, make sure you decline all the deals and offers on the way, and opt for Advanced/Custom settings so you can remove ticks next to unwanted programs.
Finally, do not be deceived by the functionality of some apps – usually, they are entirely useless and will not meet the expectations but will only flood you with ads and disturb your web browsing sessions.
