Careful wazup. Sometimes the treatment can be worse than the disease. If you panic and load your PC up with several flavours of supposed anti-spyware shit, they will fuck with each other and some will likely be near impossible to remove. Get an ad blocker. Chances are that is all you need. But if you are worried about spyware/malware infecting you 'pooter, then run a scan on your computer with whatever antivirus program you already have. If you don't have any antivirus, then why the fuck not? And install one of the free ones (AVG, for example).
