Virus Attack

People visiting my Website during the night may have found that sometimes they couldn't open the site as it may display a message like "Unable to find the Web pages". After checking with the company who hosts my Web site in their server, I was told that my computer must have been infected by certain virus like Troy or the alike. I can't understand why my computer would have been contracted by viruses, because I use the anti-virus program like PC-Cillin to safeguard my computer all the time. I think the most possible reason for it due to my BLOG. So, from now on, I will do away with some unnecessary parts on my BLOG and use a simpler template for it. Hopefully doing so, the problem will be completely resolved.
