A few cons with Full Scan (and one pro)
I apparently went over the word limit (actually, the character limit) in drafting this, so I've split it into a few posts.
Idly clicking around with my mouse on my computer (much like a monkey randomly banging on a keyboard hoping to produce a Shakespearean masterpiece), I happened to click on the
System Scan icon within the Dashboard of Bitdefender Internet Security ("BIS"). It turns out that this does a 'full' scan of the system — all files.
The scan starts (practically) immediately following a single left-click of the mouse on the icon. There is no confirmation or prior warning that files may be irretrievably deleted (apparently old versions of the software — circa 2007! — did pop up a warning beforehand). I have a neutral stance on this, depending on the other factors.
As the scan ran, 57 files were automatically & immediately deleted, because BIS detected security threats in them.
Another 13 files were flagged as dangerous at the end of the scan, but had not been deleted because they were contained within archives from which the constituent file could not be disinfected, so that the only options were to delete the entire archive or ignore the purported problem. Ideally BIS should have also offered an option to selectively quarantine those archives. In any case, after reviewing the files, I opted to delete 1 and retain the other 12.
I suspect that 4 of the automatically deleted files (probably 4 copies of the identical file) were deleted as a consequence of false positive detections. Specifically, they were reported to infections of
...\Solution1\ClassLibrary1\obj\Debug\ClassLibrary1.exe with Gen:Variant.Bulz.179246 . Those EXE files seem to have been created circa 2002, and broadly fit with the description of another user: "Bitdefender suddenly detected a code exe file infected which was created a long time ago". I would not be overly critical of the occurrence of false positives occasionally.
I am running Bitdefender Internet Security build 220.127.116.11 on Windows 8.1 (64-bit).
