Which one is better among PC Keeper, Avira Free and F-secure?
Thanks!
One of these solutions deals with PC optimization (PC Keeper) but it has antivirus protection also which in this case should be used for optimization operations. The other two solutions are focused on computer protection only and it all depends on what you want. If you're going into computer protection then I advise to use F-Secure because (based on the latest Independent Test Results) it was able to protect a PC better than Avira and had better protection rate.
