Topic pretty much tells all.
I used Ewido (recommended during another event being resolved on your forums) during the resolution phase of correcting my malware/adware/spyware drama recently. The product found considerably more items than Ad-Aware. Spybot, and Microsoft's antispyware program.
At $29.95, the cost is not that big a deal as long as the product performs.
Are there other products you would recommend?
