I recently downloaded a file which turned out to be infected, I have NOD32 Antivirus and Comodo Firewall as defences against viruses, malwares etc. When I launched this file the firewall made some blocks and ignorant of what they were I accepted the file to be executed, spiralling my computer into trouble. The logs from the firewall show that changes were made in the following folders and services:
LocalSecurityAuthority.Debug
C:\WINDOWS\system32\drivers\down HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\EnableLUA
\RPC Control\ntsvcs
\RPC Control\ntsvcs
C:\WINDOWS\explorer.exe
LocalSecurityAuthority.Debug
C:\Program Files\ESET\nod32kui.exe
C:\WINDOWS\system32\drivers\srosa.sys
C:\Program Files\ESET\nod32krn.exe
C:\WINDOWS\system32\drivers\srosa.sys
I came across this link and it has proved useful:

Some of the changes made bear resemblance to features in this link:

Unexpectedly, the NOD32 service has stopped functioning totally and the firewall only partially. I have deleted hldrrr.exe from System32\Drivers\ ,but am sure that the other changes made by this virus is certainly going to hamper the proper functioning of the pc.
I am doing the Kaspersky online scan (will post the log soon). Hijack and gmer logs are given below.
