Best Free Trojan Scanner/Trojan Remover
My top recommendation here is AVG Anti-Spyware , a product formerly formerly known as Ewido until it was acquired recently by GriSoft.
Ewido started life as an anti-trojan scanner but has been repositioned as an anti-spyware scanner by the new owners and the new name reflects that re-positioning. Whatever ever it is called it is an excellent anti-trojan and a fine anti-spyware program as well.
In my tests Ewido/AVG Anti-Spyware emerged as was one of the few products that could detect polymorphic and process injecting trojans that were totally missed by many anti-virus products. Unfortunately the free version of AVG Anti-Spyware doesn’t have a memory monitor and this omission significantly reduces the level of active protection provided. However the on-demand scanner is excellent.
I recommend that all average PC users who don’t have an anti-trojan scanner download AVG Anti-Spyware and scan their PCs weekly. I suspect you may be surprised at what you will find. AVG Anti-Spyware is also pretty good at removing some spyware infections so bear that in mind next time you encounter a spyware product you can’t remove with normal anti-spyware products like Ad-Aware.
Note that AVG Anti-Spyware only works with Windows 2000 and later so Win 9X users should consider the free version of a2 (a-squared) anti-trojan as an alternative. It’s not quite as effective as AVG Anti-Spyware but is still an excellent product.
High risk PC users such as P2P file sharers and frequenters of hack sites, should however consider Trojan Hunter or the full version of AVG Anti-Spyware both of which offer the active protection they need.
Note: The free version of AVG Anti-Spyware is actually the same as the paid version but after 30 days the active protection (i.e. memory monitor) becomes non-functional, automatic updates are disabled and kernel level self protection is turned off.
