All sites on my server blocked 'URL:mal' - no infections I can find?!

have all been blocked by the network scanner - I've searched through the files and coding and couldn't find anything.  I had been hacked a few weeks ago on a different server with http://bcwebsitedesigner.ca - but updated all scripts and recovered.  If I temporarily disable the scanner, the sites appear completely normal - no redirects - no apparent malware problems appear in the code or the browser I hit them with.  Is it more probable that avast has blocked everything on my server?!

thanks for the quick reply - i did report FP - it seems odd that these other sites all went at the same time...?  Is it possible they have blocked the whole server?
