Hi, why is there an option for "Ask" when a malicious URL is found, when aborting is the only choice?
How do I allow the connection that is actually safe?
An "Allow" option?
For the greatest majority of people an Allow button would be too dangerous, avast have stayed away from a single click option as it can A) be accidentally clicked or B) clicked when a user incorrectly believes a site to be clean.
The avast web shield has a very high degree of accuracy in its detections. Whilst you can add a site the the web shield exclusions, but personally it is best to report it in the forums for investigation.
You need to browse the Viruses and Worms forum to see the amount of alerts that people consider false positives only for it to be proven correct.
Sites are being hacked at a phenomenal rate, so a site which may have been considered legit/safe could well be hacked.
Unfortunately VT isn't so clever or rather the fact that only avast detects anything also isn't unusual and may need further investigation at other analysis sites like
http://sitecheck.sucuri.net/scanner/ or URLVoid
