edited May 2007 in Spyware & Virus Removal
Hello!

Can someone please help me with removing Downloader.Obfuskated?
AVG tells me I have this threat. I keep putting it into the Virus Vault and it keeps coming back after i turn off the computer then turn it on again.

I downloaded HiJackThis v1.99.1 after reading some threads and did what I could, but i just found out I have to save the log file and show it to knowledgeable folks. Please help me. Thanks.


Here is the log file:
