PLEASE HELP - PC INVASION!! See HijackThis Log below

[ewok]

PLEASE HELP ME, my PC has been invaded. The homepage is being reset and every time I go online more exe files are being downloaded. Have run Spybot (each time it finds 5 DSO Exploits despite fixing them) and TrojanHunter (has found 5 possible trojan files plus RECYCLER file in C Drive). When I search for RECYCLER file in explorer it cannot be found. WINDOWS and APPLICATION DATA files have become hidden and only accessible through a windows search. This all must have something to do with the atlzk.exe file which keeps appearing in Task Manager but can find no reference to this online.

HijackThis Log below, please look through it and let me know what to do - many thanks to anybody who is able to help me.
