you say you have anti spyware and spybot, running those should be fine for spyware BUT if i was you id delete anti spyware beta and install this instead because its way better at doing its job(still free) http://www.download.com/3000-2144-10045910.html

Thats what i use along with spybot(which you already have)


Just make sure you delete antispyware beta because you dont want loads of different programmes all over the shop!
