Hello, 

 

First of all, I would like to say I am sorry that I am a new member here and I haven't really done anything for this forum (I haven't even made an introduction), but I would really appreciate your help. I believe my computer has recently been infected with a Trojan. I have seen a slower response time, and my internet downloads with no use of common sense make me even more sure my PC has been infected.

 

 

I have included FRST.txt and Addition.txt on this threads files.

 

 

 

Thank you so much!
