Most forums, including this one I suspect, advise against using HJT, OTL or any other similar software unless you are fully trained.
Seedy21 has quite rightly stated that you should seek the advice of an expert if you have, or think you have, malware.
HJT and OTL are powerful tools in the right hands. You can, however, do a great deal of damage if you don't know what you are doing.
