I connected my thumb drive (last time used on my desktop) to my laptop, which indicated trojan named 'win32.autoit.ci' as 'new folder.exe'

my desktop has fully updated AVG antivirus.
It is unable to handle advanced antiviruses like norton because It is very old compu with intel celeron 1.7 ghz, 128 mb ram, 40 gb hdd, intel graphics card (probably 28 mb),running win xp, sp2.

hijackthis log is as follows-
