Whats a good freeware webscanner...

Whats a good freeware program that will scan websites for threats when I visit them? I just want to be safe

 

Thanks for the link Mark! I had no idea that Comodo had this app, and I've always been a Comodo fan so I'll check it out. One strange thing.... Using your link, I downloaded the Comodo Verification Engine. The download file was 3.7mb, but the Comodo site says the .exe file is only 1.12mb. Wuzzupwiddat? I attached a screen shot that shows the completed download in a Firefox download window, and a portion of the Comodo site. The file sizes are highlighted.... perhaps I should send this to Comodo tech support too.... anyway, thanks again Mark, and I'm going to install it and check it out in the next few hours.
:-D
