What else should I do to stay safe? In addition to Ad-Aware, use a firewall, a virus protection program, and automatic Windows updates.
Should I install a second spyware detection program?
Ad-Aware is an excellent program, but no one program is likely to catch all spyware. Installing a second spyware detection program can give you even better security. Please see the PCSC's spyware information page for details (and warnings) about other programs.
