Yelloader is a subtle adware application whose installation and activities may go unnoticed. Often, Yelloader may be brought to a computer in the form of an obfuscated VBS file which, when decoded, downloads and runs the Yelloader's installer. The peculiar thing about this adware is that it is very difficult to spot – it does not make any noticeable changes to the computer's behavior, and it does not even display ads in active Web browser windows. This adware application may load various online ads in a background process silently, which may consume some of the Internet bandwidth without bothering the user with the marketing content it browses. In short, Yelloader may be used to monetize advertising campaigns without the knowledge of the user.

It is clear that software that loads various pages in a hidden process and does not notify the user of this activity should not be considered safe. In addition to this, Yelloader's file might be disguised to look like a legitimate Windows component – for example, one version of the adware drops it's binary in 'C:\Program Files (x86)\msrtn32\msrtn32.exe,' but it is entirely possible that Yelloader may use different files names to mask its presence.

The only guaranteed way to find out if Yelloader is running on a computer is to perform a full system scan with the assistance of a trustworthy anti-virus software suite. Some users might notice a notable decrease in the quality and speed of their network connection, but this issue might be difficult to spot by not so tech-savvy users.
