It's great for such things.
You may as well know that some pests are very much like a nail in your car tire. Pull the nail and you get a flat.
I had some spyware on my PC & tried the eTrust anti-spyware Suite (actually I don't know which one as my PC is no longer working) but it was the one with firewall, anti-virus & anti-spyware & anti-adware.
I don't know if this was caused by this download or from a previous problem but now if I turn on the PC it only works for 10 seconds & then everything freezes. I now have to pay a PC technician to restart my PC from scratch & be without a PC for a while.
I just wanted to ask wether you know what caused this. Although I'm not blaming the software as anything could have caused this but I can only say I'll be very very careful of what I download in the future!
