BearShare Mediabar is adware that comes bundled with certain file-sharing applications. Normal methods of removing programs will not delete BearShare Mediabar; BearShare Mediabar's removal require methods normally reserved for more dangerous malware. As an extension for Internet Explorer, BearShare Mediabar will create advertisements and attempt to alter your homepage repeatedly without your permission. Under normal circumstances, deleting BearShare Mediabar is the right thing to do, since BearShare Mediabar has no positive aspects for the user and may contain malicious links in BearShare Mediabar's advertisement.

BearShare Shares... Adware

Some versions of BearShare and similar file-sharing applications like iMesh will also install the BearShare Mediabar adware as part of a bundled installation process. BearShare Mediabar can also be identified as Media Bar 2.0 or iMesh Mediabar, depending on the type and version of the application. These file-sharing programs are non-malicious in and of themselves, but the BearShare Mediabar component is mildly malicious in nature.

Deleting iMesh or BearShare will not get rid of BearShare Mediabar, and even directly removing BearShare Mediabar through normal methods will fail. The BearShare Mediabar adware is designed to stick to your computer whether you want it or don't want it and requires malware-removal procedures to delete.

Since BearShare Mediabar is an Internet Explorer extension, BearShare Mediabar may not interfere as much if you use a different web browser. On the other hand, BearShare Mediabar has been reported to open IE windows even if you're using a different web-browsing program like Firefox or Chrome.

Advertisements are BearShare Mediabar's Only Media

If you're using BearShare or iMesh and wondering why you're getting pop-ups whenever you browse the web – wonder no longer, BearShare Mediabar is the source. Infected systems will also endure the forced display of 'pop-under' style advertisement, as well. A third unwanted symptom is BearShare Mediabar trying to switch your IE homepage, which BearShare Mediabar will do regardless of how many times you revert the change.

This behavior is irritating but not directly malicious, but in some cases, unwanted advertisement like the ones BearShare Mediabar provides are gateways to dangerous websites. Hostile sites can engage in 'drive-by' downloading behavior and force you to download malware if your browser settings aren't unusually cautious.

Even if you're not concerned with advertisement and arbitrary homepage alterations, the possibility of advertisement being used to link hostile sites is too likely to ignore safely. Regardless of other factors, it's a good reason to delete BearShare Mediabar rather than let it stick around, especially since the programs BearShare Mediabar is bundled with are now fairly outdated!

  • Stephen says:

    I had a really good mediabarand somewhere down the track BearShare replaced it and I\'ve lost certain files or they don\'t work. I really detest this peer to peer crap. It\'s not the fist time this programe has changed the Defaults of my computer to what suits it best. My wife installed a programme and it was attached to it. I ended up having to take it to a computer geek friend to remove it along with all the nasty trogans and worms. Can\'t do that now. So I\'m stuck with it until I can find someone who knows what their doing to remove it. If I tried removing it, I\'d end up with a computer that won\'t be of much use other than and oversized paper weight
