@xzz123

Somethings wrong or ... I still doesn't  reproduce this behavior. Interesting......

Waiting for KL response.

[Wesly.Zhang]

@xzz123

If this behavior could be reproduced stably, Try to clear ichecker and iswift database. After do that, check again.

Settings -> Protection -> File-Antivirus -> Advanced settings -> uncheck ichecker and iswift technology-> recheck them.

[Ilya.Zadonsky]

Are there any changes after following the recommendations from the message above?

[xzz123]

@ilya-zadonsky

Negative, sir.

[Wesly.Zhang]

@xzz123

According to the traces, AVP collectly detected "http://bbs.huorong.cn/forum.php?mod=attachment&aid=MzIwNDF8YjZiMmFmN2J8MTUzMDI4MDQzMnwyNzA0N3w0NzcyMA%3D%3D//mv_sophia_docs/mv_sophia_docs.exe" as "Backdoor.Win32.Androm.qbms", But failed to deal with it. Does this issue only happened in "360Chrome/ 360极速浏览器" browsers?

Do you set some ignored message in KL Product settings? Restore all notification message in KL Settings and use IE browser to check this issue again.

[xzz123]

@wesly-zhang

Actually if you can reproduce it, than you can reproduce it in any broswer. Before I already tried Edge broswer.

No additinal notification is ignored.

And most important, I can not see any relations between a scan error and a Clean Object moved to Quaranteen....

[Helios_07]

Its reproducable for me, i get the same report: Clean object (file) moved to quarantine by user.

@xzz123

Yeah~ I see now. Sorry for my mistake. This issue happen on "Detected object" in Detail report. Ya... It seems AVP do not deal with some item and filter it.

When a threat local in the zip,rar,7zip or some compressed package (parent directory ), AVP don't process its log to filter/hide or improve the log event about the processing state of the thread in compressed package to list in Detected Object window. Maybe It is a beta version, So they haven't dealt with it yet.
