I also want to know how UAV actually works. It does not seem to use VT API to check file(s) if the file is malicious or not?
Of course it cannot use, something like Avira Cloud (Like F-Secure do), because you need to pay for it.
If SAP uses its own cloud, how old are UAV engines databases?
Otherwise i do like SAP a lot. Its powerful and light on resources.
I am involved in a discussion of SecureAPlus (SA+) at Wilders Security Forum, in THIS (https://www.wilderssecurity.com/threads/secureaplus-essentials-pro.441450/) forum thread.
One poster is testing SA+ Pro, & reported two false positives (FPs) in THIS (https://www.wilderssecurity.com/threads/secureaplus-essentials-pro.441450/#post-3044501) post. One of the FPs was detected by Universal AV's Avira engine. The second FP was detected by UAV's AVG engine. However, when those files were uploaded to Virus Total (which includes the Avira & AVG engines) they were reported as clean.
I find it mystifying that UAV's Avira & AVG engines reported FPs whereas those same engines on Virus Total (VT) did not. Perhaps VT uses different engine versions than those used by UAV or....... what??
REQUEST: Please evaluate & comment on this possible discrepency, either here or in the Wilders forum (I believe Hendys is a member of Wilders).
