I've used avast! (antivirus) in combination with Spybot - search and destroy (anti spyware).
I also used Norton internet security in the past but that has been over 2 years ago.
Currently I'm trying a trial of NOD32, but I had no program installed for spyware. So today I installed Spybot and did a scan and it found a lot of threats. But Spybot doesn't work very well on my PC.
I'm looking for a single program that protects against all threats. Does anyone have a suggestion?
