I use AVG, Ad-Aware, and Spybot. They all work great and they're FREE!

terminator 2 is a good anti spyware unfortunately not free but very cheap,there is a trial version which is worth a go

i recommend super anti spyware too, that is the best!! it got rid of a whole heaps of horrible spyware on my desktop and it took me alot of programmes to try get rid of this thing "Spycrush" it was horrible and superantispyware got rid of it in like 1 minute lol

for anti-spyware I think you should use SUPERantispyware. for avast it's a good anti-virus and there's no conflict with other anti-spyware

Hello I sugest Spybot search and destroy and AVG free version,you can download these from download.com.

Go to Microsoft website and use windows defender and live scan.

I recommend spy sweeper which is good for blocking system changes. Down side is it costs. Spybot does just as good for free
