Hi, I’m use the avast! 4 Home Edition, I have some questions:
I download a Winzip file, it have 25 virus, I used the Kaspersky for Personal Pro scan it find 20 virus, but I used avast! 4 scan it ,find 26 virus,why?
avast 4 is very good, why no Chinese edition?
I suggest add a function: when some program make itself to start with Windows startup, avast display some information and user can control it(yes or no).
Finally, I can’t speak English ,so if you can’t understand what meaning,don’t laugh.
Hi, your post was fine: I hope you understand my response too, if you don’t just simply ask and I will re-word it:
Avast and other anti-virus programs use different signatures to identify viruses. In general what this means is Kaspersky may be only displaying a certain type of viruses, and not their respective subgroups. This is difficult to explain, but I guess it makes sense in my mind. Basically, Kaspersky and Avast! have different signature files, therefore a virus that Kaspersky detects as 1 complete virus, Avast! may detect in sections.
Does the link leads to test or real viruses? (If it leads to an infected file, please remove the link). Are you using two antivirus with resident scanner enable at once (recommend you disable one of them if you do)?

That’s impossible to say without checking the files (and I can’t download them). If you are asking why avast! found 26 viruses even when there are only 25 files inside… well, maybe some of the files was unpacked (as a sub-archive) into multiple files and there were more viruses detected in there. Or, the main ZIP archive itself was also detected as a virus, don’t know.
The translation to Chinese is in progress. I hope the Chinese language modules (both Traditional and Simplified) will be released in the next program update.
I removed viruses link,and I’m not use two antivirus software at one time, I understand why different antivirus has different result.
The translation to Chinese is in progress. That good news.
Thank everybody.

I never heard of this before. ???
I don't think that Kaspersky and other anti virus developers (norton, avast!) share their signature files with over companies? It's why if you look into the Avast! database and search *.* for known virus the number it finds is not that large. This doesn't mean Avast! doesn't detect a numerous amount of viruses it may just section them differently than other antivirus software?
(Someone may want to verify this, but I’m pretty certain its true).
The answer Igor gave is probably more accurate though.
