PUABundler:Win32/Rostpay

PUABundler:Win32/Rostpay is a detection for a potentially unwanted program (PUP) that can have a negative effect on the computer once installed. Normally, programs detected as PUABundler:Win32/Rostpay are those apps that are integrated into legitimate software. While the host program itself is valid, any bundled products from different developers can result in misbehavior or conflicts. So, to protect the computer from this unwanted installation of third-party apps, antivirus programs alert users about the malicious software installer package and identify it as PUABundler:Win32/Rostpay.

How does it infect the computer?

PUABundler:Win32/Rostpay is spread via online promotions, especially advertisements and email campaigns. Installing the program itself may not harm the computer because it is deemed legitimate. However, there are occasions wherein other products that come with it may not have the same reputation and could cause damaging effects on the computer. The reason for creating such bundled apps is to promote them by integrating with host software and running a simultaneous installation. Basically, programs identified as PUABundler:Win32/Rostpay are taking advantage of a sneaky approach to entering the computer.

Users have the option to opt out of the installation of files that are identified as PUABundler:Win32/Rostpay. However, some users can accidentally install the bundled applications when running the setup while disregarding the options provided during the installation.

How does this malware operate?

The main objective of PUABundler:Win32/Rostpay is simply to install the supplementary software. Obviously, the developers are involved in a pay-per-install campaign, and they receive revenue from those software providers by incorporating the installer files into the main application. As mentioned, PUABundler:Win32/Rostpay does not require the compulsory installation of third-party applications because it provides options for users to opt out.

Symptoms

In cases where PUABundler:Win32/Rostpay has infected the computer, users may notice several symptoms. One of which is the significant slowdown in overall system performance, especially with affected applications taking longer to load or respond. Additionally, users may encounter unexpected crashes or freezes on applications due to a lack of system resources. Aggressive types of pop-up ads and redirects while browsing the internet could also be a sign of PUABundler:Win32/Rostpay infection.

Moreover, the infected computer may exhibit changes in the browser settings, such as a modified homepage or default search engine. This can lead to unwanted redirects to suspicious websites. Furthermore, if you observe unexplained data usage or network activity, it could be a sign of PUABundler:Win32/Rostpay communicating with external servers.
