I have installed Avira antivirus program on the computer of mine. well from yesterday night I have noticed that TR/Dldr.Chepvil.J.21 has been detected by the antivirus program which I have installed on the computer. I have done a virus scan and moved to quarantine but it did not worked for me at all. Let me know how can I get rid of TR/Dldr.Chepvil.J.21 from the system of mine. I am waiting for the prompt replies of yours. Thanks a lot in advance.
