Hi :
A "trojan ( Trj ) is NOT a "Virus" ; they are Best dealt with by an
antiSPYWARE/antiTROJAN program . Did you ever install this type of program,
like the FREE Version of "SUPERAntiSpyware" from
www.superantispyware.com ? I see when you were here in Jan, you had
Symantec/Norton antivirus; have you removed it and gotten Avast ?
Never, initially, attempt to "Delete" what a security program has "Detected";
ALWAYS should try to "Quarantine" it . Is this what you mean by "Remove" ?
