Old PC full of virus!!!

The old pc, my first pc i have, has a lot of virus inside when i came back from Bukit Jalil,

can't do anything to save it too, so i have to format it (i want to do it long time ago).

After i format it, i need to find, search, install and update all the drivers back(didn't backup the drivers back then), it takes me few hours there... 

Anyway, i have complete done with it now, install new software on it, use free antivirus(AVG Free Edition) and firewall(PC Tools Firewall Plus), not bad at all, but the firewall block way too much of things which is a advantage and disadvantage of it. I also download and install OpenOffice.org instead of microsoft office, why? It is totally free and almost same function as microsoft office! 

For music, i have install 千千静听, a chinese music player that can download lyrics for itself.

For movie, i have install K-Lite Mega Codec Pack and The KMPlayer to play all kinds of movies format.

Now, my old PC are virus-free and good as new. Shit! I use all of my time to do this, how about my FYP?
