If SpyStopper Pro (ssp.exe) is adware then we are probably wise to avoid it, as we do Google, Yahoo toolbars and other adware.
However, this is about why or how avast! would unilaterally delete SpyStopper from timarose's PC when it is not identified as a threat at
jotti (which includes Emsisoft's own A-Squared),
virustotal, or by SuperAntispyware, Spyware Terminator or Threatfire.
