i'm also a member of another forum, in that forum, we test virus samples.
i downloaded a pack of 208 viruses, and i ran a scan with baidu AV ( With Cloud Enabled ), and it detected all of 208 samples
BUT, when i tested it with Cloud Disabled, it only detected 10 items (Avira was on and updated)...
...
Well, we only have a very small offline virus-database. And the sync with avira official vdb is not always on time.
So, on the offline instance, we can only use the very small virus-database & Heuristic Engine...
BUT, some of our engines are not released...
