Taking to long to scan removable media

[alihonarmand]

Hi
I tried to scan a removable media of 4GB but faced some problems. in first steps everything went fine until scan reached an .exe file which had a suspicious name like this
<<AUTOIT SCRIPT>
and scanning stopped here, better to say slowed down. what's wrong? I know that "AUTOIT" is a virus but I have never had any problems with this virus before.
how can I remove it?
thank.
