If you mean Spywareblaster I would reinstall that.Malwarebytes free you could also download that as well.And run SuperantiSpyware as your main Anti-Spyware program and maybe once a month run malwareBytes.Windows Firewall if you don't go into any bad sites should be Ok But unfortunately in this day and age a better firewall would be help.
agree with buteman reinstall spyware blaster - as this doesn't run all the time there should be little conflict - it does is stop you browsing hazardous sites and picking up some nasties hidden in webpages.
a better firewalls is a good idea if you surf for long periods - I use Comodo but many prefer a little more help setting up so try Online Armor (sic) or Zonealarm - all have free versions available
It has a blacklist which you have to keep uptodate for it to be of max use. Autoupdate isnt available in the free-version , but it only takes a few seconds to get an update (just need to remember.. set a reminder to pop weekly??) Your browser is then set to use this database to "protect" itself You can add your own "protection" or choose to unset the downloaded "protection" at an item level More info from click here
I agree with Granny and buteman SuperAntispyware, malwarebytes, a-squared, spybot all good to have and use and a good firewall (I use Comodo, ZA got a bit needy)
