AVG8 won't update, Rootkit.Agent.V found

Hi Chaslang et al,

I have encountered a problem. Since a week back in time my AVG8 won't update, giving a "connection to server failed" message. Uninstalling and updating to the current AVG8.5 has not resolved this issue. When posting in the AVG forum it has been established that I cannot actually connect to the avg update server address of guru.avg.com, which will give a "webpage cannot be displayed" message.

My system shows no general signs of being infected, but scanning with my already installed MBAM revealed three instances of "Rootkit.Agent.V":

C:\WINDOWS\system32\dllcache\wadv07nt.sys
C:\WINDOWS\system32\drivers\wadv07nt.sys
C:\WINDOWS\ServicePackFiles\i386\wadv07nt.sys

I have now run the logs required by you and appreciate your response. Thank you.

 

MG Tools log.

 

Hi Tim,
thanks for your response. Those two files belong to my Nik Sharpener software. Since March 20, I still cannot update my AVG8 installation. How can I resolve this issue when my logs come out clean? What do you think of that Rootkit.Agent.V? Is there any point in running gmer or some other additional scanner?

 

MBAM came out clean. Since my inability to update AVG8 is linked to the fact that I am actually unable to access the AVG update server guru.avg.com using IE7, what would cause that? How could a certain IP address be blocked like that? Should I look into some registry entry being affected or just ditch AVG, which I have used for years? Anyway, thanks for your time this far Tim.
