This page aims to help you remove Аds by Аlex Chrome “Virus”. These Аds by Аlex removal instructions work for Chrome but also for Firefox and Internet Explorer, as well as every version of Windows.

Аds by Аlex is an Adware-based product. It has been programmed to serve the marketing industry via efficiently promoting goods and services. This happens by making your browser distribute a big number of banner, pop-up, box and other online ads to your computer screen. No browser – neither Explorer, nor Chrome or Firefox could avoid producing ads, once your system has been infected with this piece of ad-generating software. Continue reading for more detailed explanations of the typical behavior and expected effects of Аds by Аlex once inside your system.

Are Adware-based programs viruses? How about Ads by Alex “Virus”?

So far we have no proof that Adware-type programs could be classified as malicious. Truly, they might be very irritating and even sometimes intrusive, but no malicious activities are typical for them. So Ads by Alex is not a “Virus”. Adware does NOT lead to file encryption or system crashes. Its effects have never involved blackmailing you, corrupting your system or some of your data or destroying anything you possess. Nor have they involved personal information theft or espionage, which are characteristics of real malware like Trojans and Ransomware. The only considerably intrusive activity that is characteristic of programs like Аds by Аlex is the research they may conduct revolving around the interests and personal preferences of the affected users. When it comes to ad-producing software, this research may involve carefully scrutinizing your browser history. The results are comprised of the webpages you visit and products you usually review or search for online. Then the generated ads include only such or similar webpages, software and goods. Some users could feel that this activity is an act of invading their privacy. Apart from that, nothing is considered suspicious when it comes to Adware.

Possible negative effects

Although, we are not discussing a virus in this article, we must mention that Аds by Аlex could sometimes contribute to a worse system performance. This happens especially to machines with scarcely enough resources. The generation of many pop-ups and other diverse ads might slow down a computer with a smaller resource capacity. This is not that serious and can be fixed by closing down the produced advertisements. Another potential unpleasant effect of this Adware is that sometimes it can broadcast too many ads, which could completely cover your browser window and leave you unable to load any pages. Such a consequence might disturb you very much, but it cannot harm you of your PC.

Possible sources of such ad-generating programs

All known ad-producing software, including Adware and browser hijackers, could be found in various places. The distribution methods such programs exploit are very diverse – from torrents to drive-by downloads; from infected websites to spam. So far the biggest number of infections is still caused by installing a software bundle. Please note that bundles are rarely dangerous. They represent sets of apps, programs, sometimes games, that are available online, usually for free. There could be many useful programs inside them that might be very helpful or necessary for your system, but there might also be browser hijackers and Adware. Simply downloading such a software mix won’t leave your PC contaminated, however, improperly installing the program bundle surely will. To stay away from any ad-broadcasting program, you have to learn how to opt out of any and all of them. For that purpose, you should use the installation feature that will allow you to do that. Such options are the Advanced and the Custom ones – do not think twice, choose only them. When you do so, you will be shown a full detailed list of the contents of the bundle during the installation process and you will be able to remove all the potentially unwanted programs from that list.
