I used this antivirus on my old computer, which was almost literally wooden. As long as it was just about browsing the Web, everything was OK, but the very moment the program would start a regular update, my machine would nearly hang up and remained in that state until the update was complete in about three or four minutes. That's why I would not recommend using this software on low-performance computers.
