This product seems to be fairly new i think it came out around october of last year. The weird thing is its free for romanian users and cost for others. There is no english version that i know of (yet). Here is the romanian site for the product. What really seemed interesting to me is there are no options or popups with this product. Here is an interview with Bitdefenders Senior product manager. He definitely has something interesting things to say about the product.
Here is just a small portion of the interview
Usually, antivirus solutions, once installed, alert the user on the fact that the system has not been scanned, mentioning the fact that there are 'issues'. Initially, we didn't even plan on implementing an on-demand scanning system, at this point, the system being available only to help those who write product reviews.
Our Autoscan actually works by scanning once a day all the critical system areas (System32, Program Files) and once a week it sweeps the entire system, regardless of the size of the hard drive. All this happens without any impact on the performance of the machine, tests being made with games and applications.
This background scanning relies on a system that could be perceived as being similar to the ‘idle’ scanning implemented in other solutions.
Normally, idle scanning means that when the application finds CPU resources, it steps in and scans the system. With Bitdefender Antivirus Free Edition we not only took the concept to another level but we reinvented it all together.
Upon installation, a calibration library checks the CPU and hard disk performance in order to align the algorithms fine-tuning the impact in system performance with the overall system performance. Basically this ensures that whenever needed, Autoscan can run in background while heavy-duty tasks (gaming, for instance) are being performed in the foreground, without interfering with their performance.
This might not seem like something out of the ordinary, but we do it with a millisecond precision. For instance, let’s take Photoshop. If we look at the performance graph when it loads, we can see that it doesn’t take up all the system resources instantly, instead the graph oscillates.
In a simple test, if we were to compare how fast Photoshop would start on two identical computers, on one machine, the program runs without any interference, and on the other a scanning thread is launched.
While they would both start in precisely the same time, in the meanwhile, the scanning thread manages to scan somewhere around 2 files, which means that the scan is not fast, but it doesn’t interfere in any way with the regular processes.
Here is a discussion about this product at Wilders security forum.
