For the past week my anti-virus program (Trend Micro) has been detecting that Troj_Dloader is on my computer. When it runs its checks it says it is unable to quarantine this trojan. What this virus/trojan is doing is constantly asking if i would like to install Win Antivirus pro. For 4-5 days these pop-ups would ask to install this program. But for the last two days my computer has gotten extremely slow. Advertisements of all sorts are being thrown on to my computer screen. It has gotten so bad that I have had to shut down that computer and go onto another one to type for help. I have tried following to system restore to an earlier time, but to no help. I have also followed the instructions on how to remove this trojan from the Trend Micro web page. (Delete the filename from the list of processes) The virus says it is in my temporary internet files, but i have also deleted those. I am not very good with computers, but would appreciate any help relating to my problem. Thank you.
