Looking for new layout for this blog

Hi Everyone! It is Wednesday here. I got very busy lately. I needed to take care of some things. So, I haven't visited this blog for a while. And I would like to change the template or layout of this blog. I have been looking for nice layouts or themes. However, I really want to avoid downloading some themes from the net as I don't to want to get any virus. You know, malware and trojans are drastically popular over the net nowadays. I want to be very careful. So far, I have a very good antivirus, Avast. But, you don't really know when this virus gonna hit your pc. I trust my antivirus. Why hassle? Anyhow, I am looking around for themes on the net - the themes where I can directly copy and paste the code here.
