Phishing and Network Attack

I registered myself with a forum about paintball. One of the member wrote in my forum that he can't access my blog and worse still another member who said he accessed this blog using IE was connected for a few seconds and then bust. 

I experience this problem too but I know it was my antivirus that blocked the site. 

I tried to access villianpaintball blog and get this.

Then the side bar on my blog showed me this message below. 

During that duration of time when most of the sites that I tried to visit was blocked and when I checked my Karspersky report it was because there was a network attack and Karspersky was taking its action to block the attack. At the same time there is also phishing activity on my network. 

I am grateful for the comments by the member of that forum. Or else I will not know that I was attacked by online activities.
