Hello m8, firstly, I would say download Avg Antivirus from www.grisoft.com and use the free one, install it, update it, and run it, also, download spybot search and destroy as suggested above, you can get it from www.download.com , also download the microsoft spyware program from www.microsoft.com and then, once all installed, click start and then run, and type in msconfig. The system configuration utility will open up, click and startup, and untick everything except the spyware programs, your broadband modem software if any, and your antivirus apps. Click apply, then ok, restart windows, and see how it goes.
