Hi, Sorry to jump in on this thread but I have avast free on a win7 pc and it sometimes gives me a warning about threats on a web site, and a site ive been to before without problem. When it first happened I got outa there real quick, but after a little while of this happening I tried accessing the same website on another pc on my network (which has the same version of avast) and theres no warning. Hasnt done it for a while now but it was strange. Not bashing an excellent product but just adding my 2 bobs worth.
Please start your own topic (so it doesn't confuse/hijack this one) and the site can be investigated. Avast it probably the hottest defence against what is the most prevalent means of infection and that is sites that have been hacked. There are very few AVs even looking for this, much less capable of detection.
The web shield has been very accurate in its detections, of all those I have investigated the very greatest majority have proven to be good detections as the many topics relating to such detections show. That isn't to say it is 100% as nothing is 100% and is true of all security software.
Without detailed investigation all this is speculation as the web shield scans in real time, so it is entirely possible that a) the site has cleaned out the inserted code of the hacking attack or b) if an incorrect detection the signature updated/corrected. But without information no one can say for certain.
