avast! got 9 passes / 19 fails in test history.
it also failed the most recent test under WIN XP!
shall i re-consider it? 
Search the forums for āBulletinā.
s2k, another virus repport bulletin :-
Some avast users are becoming tired to discuss thisā¦ Methodology, independency of the testers, etc. etc.
What can we learn more? What can we see? NAV, McAfee and the others with 100%
Sorry, itās not up to you but Iām getting tiredā¦ Can you search the forum for the word ābulletināā¦
Maybe Vlk or another Moderator should sticky a thread explaining the low Bulletin scores. It would be well worth it.
I respect your opinion but disagree. This will make more noise about nothingā¦ A sticky thread? We have more important thinks to solve, help, read and do. Ok, Iām really upset with virus bulletins 
Iām inclined to agree with Technical, especially since my gut reaction every time we get one of these threads started is āHere we go again ā g-r-o-a-n.ā
Considering the number of threads already on the forums here explaining in considerable detail why Bulletin ā and many other ā test results and comparisons are of little or no real value for anyone looking for serious and objective product info, I donāt see any point in continuing to beat our collective heads against the wall on the subject.
Just my personal opinion, of course ā but hopefully itās at least partially shared by the team and mods.
What about a brief sticky and locked posting linking to some of the more informative threads on this? And lock those too while youāre at it?
Best to all ā and pass the aspirin :

Until people learn a litte bit more about Virus Bulletin and how the tests are done itās real easy to take too much stock in them.
Itās only human nature to want the one with the best score.
As for me, I tried out several different antivirus programs and went with the one that worked best with my set-up and it doesnāt hurt that support(this forum) is second to none.
Gee it seams like this is another post to rehash old news.
Totally distorted and bias news at that. As Technical already mentioned, do a search and youāll find lots of discussion on this subject. It has already been totally discussed.
Enough is Enough.
Thanks
Lots of people donāt know this. We should all try to be a little more understanding. As for always telling other people to do searches to find infoā¦Some people donāt even know how to do that very well.
maybe some of you already tired discuss it.
but itās the first time for me.
the website claims avast passed VB100 test so, naturally, i went to vb100 website to check out, then i foud the result. later i found avast missed a virus sample i haveā¦
however i like avast, it just looks good and works well, i recommended it on other forums just now.
i just need some more confidence with it. users of other AV can say their product got ādesgined for Windowsā logo, got level 2 Check-mark, passed VB100, what can i tell them?..
but i still support avast 
s2k, sorry if we complain a little about your first postā¦
Your posts are wellcome but, you know, sometimes we get tired.
Today is another day, letās start again. Wellcome to forums.
s2k makes a good point when he says ā¦
āi just need some more confidence with it. users of other AV can say their product got ādesgined for Windowsā logo, got level 2 Check-mark, passed VB100, what can i tell themā?..
So we should tell him things that he can tell people about Avast. One being the support forum, which is great for Avast support. Another being that Avast is not bloated and runs smooth. Smoothe easy installation. Frequent updates. ETC!

OK, letās discuss your concerns one-by-one:
i just need some more confidence with it. users of other AV can say their product got "desgined for Windows" logo
The Designed for Windows logo is indeed a nice thing. To get it, a program has to meet certain criteria (user-friendliness, proper uninstaller etc etc.). But please keep in mind that itās not an AV certification. All software types (be it text editors, video grabbers, home furniture design or AV softwares) have the same criteria to meet. That is, no virus testing is done at all.
Furthermore, not all users really care if the program strictly follows the Designed for Windows logo requirements. All those little things like default install location, registry keys etc. etc.
Stability is also an issue ā but in this case, avast! is a superior product. All in all, we somewhat felt that itās probably unnecessary to give MS yet-extra money just to get a colorful GIF that we could stick on the website.
..., got level 2 Check-mark...
Checkmark is generally considered as an easier variant of ICSA. Both of these certifications cost a lot of money so we basically decided to go just with one of them. We picked the harder to achieve. That is ICSA.
...passed VB100, ...
Unlike most people on this forum I personally think that the VB tests in fact DO have a value. What doesnāt really have a real meaning is the VB100 logo. I mean, to get a picture about the the real result of a test, you absolutely should read the magazine. It usually explains what went wrong if a product failed.
Since the VB subscription is quite pricey and 99.9% of people donāt have access to the magazine, we always try to explain in detail what went wrongā¦(I mean, only if avast fails. Otherwise weāre eagerly expecting ovations. :)) Thatās why I suggested searching for older contributions on the forum.
BTW it probably only makes sense to monitor the last few tests (e.g. last 1-2 years) - or you really DO care that much how a product performed in 1998?
Thanks
