Avast! performance was pretty poor for my point of view.I am hoping to see better with 2015 version.They improved their reaction times alot over this month so we will see what happens with ahead versions.
http://www.av-comparatives.org/wp-content/uploads/2014/09/avc_factsheet2014_08.pdfThe results are based on 669 live test cases
669?? but there is more than 50,0000 malware coming out everyday.This is like a drop in the bucket!! So we have like millions and billions of samples for like 1 month and they are testing against a few hundreds for 1 month when 669 or even a few thousands for just 1 day test wont be enough.
If you want to go to suspicious sites, just prepare to be infected anyway and make the precautions as backups and not storing anything even moderately sensitive on your machine.
I have mentioned some flaws about these tests earlier on.The usual points about static testing are:
a) the tests are carried long after the real infection took place, so it's kind of useless from today's point of view
b) the tests are carried without any context state information. Such information - if there is file named "document.doc .exe" in email, this is enough to ban the execution
c) the proactive tests are carried only with the signature engines - they don't test the other generic protection engines the products may have
d) the tests don't know anything about the relationship of the samples. If you detect the dropper, you don't have to detect the dropped binary.
