What is the arenabg[.]ch site?
arenabg[.]ch is the address of a Peer-to-Peer sharing website. It invites users to download pirated software and media via Torrent files. As well as infringing copyright laws, this site uses rogue advertising networks. Visitors to websites that employ this monetization technique are redirected to various other untrusted and malicious web pages.
Web pages that use rogue advertising networks promote other dangerous sites by force-opening them. Alternatively, the redirects can be caused when content (e.g., ads, buttons, links, etc.) presented in the websites is clicked.
These rogue pages often host intrusive advertisements such as pop-ups, banners, coupons, surveys, full-page, and others. These ads pose a threat to device and user safety. When clicked, intrusive ads can redirect to dubious/malicious sites and some can stealthily download/install software including PUAs, which are commonly proliferated through intrusive advertisements and untrusted download channels (e.g., Torrent websites).
These unwanted applications may seem legitimate and harmless, and offer various "useful" features (these are rarely operational). Fake anti-viruses are prime examples of this typeof PUA - they require activation (i.e., purchase) to perform the promised functionalities, yet following activation, they remain nonoperational.
PUAs can have dangerous capabilities. Some can force-open harmful web pages. Adware-types run intrusive ad campaigns and another type called browser hijackers operate by making modifications to browser settings and restricting/denying access to them to promote fake search engines.
Most PUAs can track data. Information of interest includes browsing and search engine histories, IP addresses, geolocations, and even personally identifiable details. The collected data is then shared with and/or sold to third-parties (potentially, cyber criminals).
In summary, unwanted software can lead to system infections, serious privacy issues, financial loss, and identity theft. Therefore, you are strongly advised to remove all suspicious applications and browser extensions/plug-ins without delay.

There are thousands of websites that use rogue advertising networks on the internet - liveonscore.tv, youtube-to-mp3.org, x2convert.com, Moviesjoy, and anitube.site are just some examples. Visiting and/or using these sites can result in a wide variety of problems. Due to the widespread use of rogue web pages, you are strongly advised to exercise caution when browsing.
How did adware install on my computer?
PUAs are distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".
Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.
Some PUAs have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.
How to avoid installation of potentially unwanted applications
You are advised to research all software before download/installation or purchase. All downloads must be done from official and verified sources, since dubious channels such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders commonly offer deceptive or bundled content.
When downloading/installing, read the terms, explore all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features, etc. Intrusive ads may seem normal and harmless, however, they can redirect to various dubious web pages (e.g. gambling, pornography, adult-dating, and many others).
If you encounter ads or redirects of this kind, inspect the system and remove any suspicious applications and browser extensions/plug-ins immediately.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
