I had that product on my computer. I was suspicious of its effectiveness because it always found the "welchia worm" everytime I ran it, even if I ran it again immediately. How's that possible?Something seemed phony to me.
So I deleted it.
I went back to Ad-aware from Lavasoft. It's free and hasn't found the welchia worm yet. Ad-aware from Lavasoft is totally free. Plus, I paid a fee for the Webroot product. Also when I installed the Webroot update it forced itself on me, popping up everytime I signed on and I couldn't cancel it. I hated that! and soon deleted the entire program even though I'd paid for it.
call me: Happy with Lavasoft.
It's not free if you want the update packages. I just got a new update package yesterday on my Ad Aware (I paid their fee). Spy Sweeper also has a free version, again, if you don't care for regular updates (I pay the fee for that, too, and do get the updates.
There's new spyware and trojans popping up all the time, so I feel more comfortable staying updated.
