Hi stone428,
You have to be really careful with what you download (specially programs), there are lots of junk & infected files around now. See here for virus info:

Be wary of exe & zip files
Make sure you've got a good AV program & keep it updated. Spyware & adware programs are a good idea, too. Scan files before opening!
Unfortunately, LW can't control what people share - good or bad. After a while, you'll get to know what looks suspicious. You can always use the junk filter to mark files that look weird (no bitrate, ALL CAPS, L_I_K_E T_H_I_S etc).
See here for how to use Bitzi to check files:

Good luck!
* If you bought LW, then it's Pro from the official site
www.limewire.com ?? If you bought anything but Pro from the LW site for US$18.88 then it was a scam!
