The safest way to upgrade the system to SP2 is to buy a Microsoft CD or download a full version from the downloads.microsoft.com website. Then, install this version on your computer.

Be careful with malware : Even if you have a firewall installed, you need to be careful with infected e-mails, websites that exploit browser vulnerabilities and adware adware. You accidentally installed it on your PC.
