Question about Agent.ANA Trojan?

Hello!

I have a problem with Agent.ANA Trojan,which I can’t remove. I tried everything : XoftSpySE (it is the only one that finds it),but after removing it, trojan just comes back.
That’s what it looks like,when I scanned with XoftSpySE:
Agent ANA Trojan (Type:Registry Key)
Threat Level : Severe Risk
Object: software\tdss\injector\*

I tried scanning with Ad-Aware (didn’t find) it and AVG Anti-Spyware (couldn’t find it as well)

How do I remove that trojan,cause after I browse internet and click on a link it redirects me to completely different weird websites (ads/scam…etc.)
