Win32:Adware-gen is an adware program that might run on users' machines silently

Win32:Adware-gen virus

Win32 Adware-gen is a name under which Avast security software detects this potentially unwanted program. The adware program typically enters computers using software bundling – a technique which allows developers to hide unwanted applications within Recommended or Quick installation settings of legitimate program installers. The PUP is capable of executing several changes to the targeted machine and may attempt to install additional questionable software. 

Name Win32:Adware-gen
Type Adware
Main dangers Malware infection and exposed personal data
Targeted browsers Google Chrome, MS Edge, Internet Explorer, Safari, Mozilla Firefox, etc.
Symptoms Invasive ads in various forms, redirects, slowdown of the browser or/and PC
Distribution Software bundling, malicious sites
Elimination Download and install Reimage. Otherwise, check manual guide below

Win32:Adware-gen [adw] virus attacks all installed browsers, including Google Chrome, Internet Explorer, Safari, Mozilla Firefox, etc. However, adware is a sneaky application that might be not noticed by users at the start, especially if they never saw PUP in action before.

There might not even be a process in the task manager (or it might hide under a legitimate name), neither high activity that would indicate the infection. Nevertheless, users soon notice an increased amount of intrusive ads (in the form of pop-ups, video-ads, in-text links, banners, offers, deals, etc.), obnoxious redirects and, in some cases, a slowdown of the browser or/and the computer.

As soon as it is apparent that a suspicious application is interrupting normal browsing activities, users should start thinking about Win32:Adware-gen removal. As this application is quite tricky to detect, we suggest using Reimage for prompt elimination of the PUP. If you do not want to install additional software, however, you can make use of our illustrated guide below.

Another very distinctive feature of Adware-gen is that installation of additional components without permission. The installed unwanted programs may include:

  • Toolbars;
  • Search engines;
  • Add-ons;
  • Browser hijackers;
  • System optimizers;
  • Codec packs,[1] etc.

Most of these apps are completely useless and only clutter the machine. The biggest problem is that the more unwanted programs are installed, the more significant is the possibility of severe malware infection. Generally, adware is legal software which is created to display advertisements to users. However, the tunnel of redirects and accidental clicks on malicious pop-ups might not only infect a machine with other viruses but also steal sensitive information, including name, address, credentials or even bank details.

Security experts[2] also observed Win32 Adware gen gathering search data, IP address, links clicked, websites visited and other non-personally identifiable information. This allows developers to research target's interests and control his/her browsing habits by displaying sponsored content.

Without any doubt, you should remove Win32:Adware-gen, as this piece of software, will not only annoy you to death with ads but may also expose your PC to malware infections, as well as snatch your personal information without you even noticing. Identity fraud is a serious problem, and you should do everything to avoid it.

Win32:Adware-gen adware
Win32:Adware-gen is an adware program that displays intrusive ads and disturbs browsing sessions.

 Adware can appear on your machine after freeware or shareware installation

There is probably no person in the world who would like to see invasive ads deliberately, every day. Adverts are the plague of the current time, as an average person is exposed to about 5000 ads a day.[3] There is nothing wrong with marketing techniques, but we believe that tricking users into installing software that can harm your PC or even steal sensitive information is not a right thing to do.

Adware and other PUP developers do precisely that. They use software bundling to inject unwanted programs into as many PCs as possible. Unfortunately, the only way to protect yourself from these unwanted programs is to be attentive during the installation process of the application, even if it is a simple 3D screensaver. Any free software can contain search engines, toolbars and other useless apps within its installers. Thus, take a good look at what are you clicking – pick Advanced or Custom settings, so that all the additional components could be eliminated before the installation of the desired software is complete.
