BestOffersNetworks.SAM  is an adware installer, not adware per se.  It claims to be a Skype answering machine.  BestOffersNetworks.SAM was made by Best Offers Networks, formerly Direct Revenue, LLC.  Direct Revenue, LLC was a notorious developer of spyware.  It is no longer in business after several court cases.  BestOffersNetworks.SAM is still considered a threat.

Best Offers Networks stress using Add/Remove Programs to remove BestOffersNetworks.SAM instead of using antispyware programs.

Add/Remove Programs can uninstall the adware installer, but it can’t uninstall the spyware.  You will still have symptoms of a spyware infection including pop-up ads and slower performance speed.  To prevent software errors in removing BestOffersNetworks.SAM, it is highly recommended that you first uninstall the main program by using Add/Remove Programs, and then remove the spyware with SpyZooka.  SpyZooka will remove the spyware, 100% guaranteed.
