I stupidly download BearShare. I have uninstalled it in all the usual places but it has taken over the firefox opening page of Google with a BearShare one. The problem is not on the laptop I am using but on a new Acer laptop with Windows 7. Help!
I did some very quick research for you. BearShare is apparently a legit program but many of the sites that allow you to download it attach malware, adware, etc. to it. BearShare itself the way you describe it sounds like it has an automatic reinstall feature similar to AOL services that never seem to leave your computer no matter how hard you try.
First I would uninstall the BearShare program and run a registry editors cleaner. Either use Microsofts and/or use the Comodo System Cleaner which can be found here ( http://www.comodo.com/home/support-maintenance/sys
Then reboot and see if that got rid of it. If it didn't I would uninstall again and try to find out where it is reinstalling itself. AOL had that feature and somehow I finally found it and I had a problem with HP printer errors where uninstalling and reinstalling did not work so I uninstalled both AOL and HP then went into the Registry Editor files (regedit) and cleaned out / deleted anything that had AOL or HP letters together, as well as every single file folder anywhere on the computer. Once I did those things, AOL is gone for good (finally), I reinstalled the newest version of software for my HP All-in-one printer and it is finally working again the way it was originally intended.
They all say going into registry editor files is dangerous, but I think that's just because these malware companies all hide their re-occurrence items in there so they never go away.
Try to run Malwarebytes (an anti-spyware program) in Windows Safe Mode to see if it can detect any virus or spywares that were not detected in the Normal Mode.
Be careful when you work with registries. If you don't know what are you doing, you can mess up your computer and it will not work properly.
go to about:config page in firefox and reset all settings that has bearshare in value to default, by right clicking that settings item and then Reset popup menu item. Go to Tools->Options and then below Home Page: controls click button, Restore To Default.
I'm not sure about this one but I had to do it, go to Tools->Add-ons then Extensions tab, then disable extension titled DataMngr, and that should be all, it worked for me.
The safest and most thorough way of cleaning it out of your system is to download Revo Uninstaller, run it in advanced mode and press delete all when prompted. Do NOT go messing about in your registry unless you are a real expert. The other way is to go into system restore and tell your computer to restore to a date & time before you downloaded Bearshare. Just remember that any software you installed since that date will be deleted so back it up first. Good luck. Bearshare is a pain in the Jacksy!
It's an easy mistake to make, I did it myself some while back and it was a real pain to remove. Don't worry, it is not full of malware but it will take over everything you try to do. You have 3 options:
1. Install Revo Uninstaller freeware version - http://www.revouninstaller.com/revo_uninstaller_fr
