An art topic

I'm not sure if this should be here, it has to do with art, but if doesn't belong here, sorry. :(

I'm into computer graphics and my computer is dying constantly until I got this new computer. But I wanna keep it nice and virus-free. The problem is that this makes me very afraid of downloading things, including brushes for PSP7. Does know have a VERY VERY trusted site that they go to for swirly and grunge brushes for PSP7? Like, that you actually go on often and never got crap on their computer from? If you do, can you list some I miss my collection of brushes. They improve a banner and icon so much.

Unless there is a serious flaw in PSP7, i seriously doubt you can get a virus or malware from downloading a brush.
If you want to avoid virii, you mainly need to avoid files that contain executable code. This includes .exe, .bat, .scr, .pif and .com files. No, .com files has got nothing to do with the internet domain .com.
