ok heres what i would fix:
O2 - BHO: (no name) - {549B5CA7-4A86-11D7-A4DF-000874180BB3} - (no file)
O16 - DPF: {B8E71371-F7F7-11D2-A2CE-0060B0FB9D0D} (CDToolCtrl Class) - http://free.aol.com/tryaolfree/cdt175/aolcdt175.cab
O16 - DPF: {AC2881FD-5760-46DB-83AE-20A5C6432A7E} (SwapIt Control) - http://mirror.worldwinner.com/games...apit/swapit.cab
O16 - DPF: {62969CF2-0F7A-433B-A221-FD8818C06C2F} (Blockwerx Control) - http://mirror.worldwinner.com/games...x/blockwerx.cab
and this one is questionable:
O17 - HKLM\System\CCS\Services\VxD\MSTCP: NameServer = 207.99.0.1,207.99.0.2
if the domain is not from your ISP or company network, have HijackThis fix it.
Overall, it looks pretty much clean
