BestCleaner is a rogue security program which is presented as an application that can help you optimize the computer and delete various files that were left over by uninstalled programs and are not needed anymore. You’re offered a free system scan and, once it finishes, you’re informed about different problems with the PC. The program assures you that there’s nothing to worry about, that you’re just one step away from solving them all – you only need to click on the button and BestCleaner will do the rest. But the situation gets more interesting from there, and not in a good kind of way.
You’re told that you need to pay for a license if you want to use this program to its full capability. Paying for software is normal, but when you’re first tricked into thinking that it’s free and then told that it’s actually not, it’s certainly a red flag. To top that off, BestCleaner doesn’t really do what it promises to – it performs some operations, sure, but it doesn’t really improve the performance of the PC, and actually makes it worse. It also constantly needs to be updated, but those are not the updates that can be considered good – additional malware is installed on the computer instead, and your Internet browser gets infested with various kinds of advertisements.
If you see your PC working slower than usual, then it’s certainly time to do some maintenance, but BestCleaner is not the program that you should use for it. The same goes for DiskPower, MaxPerforma, MyPC HealthCheck, Win Tune Pro, and many others like this – they’re only created with a purpose of making money off you. Its developers don’t really care what happens after that – their mission is accomplished. So avoid installing malware like this on the PC, and only pick Custom installation when installing new software – it can be put on the computer automatically if you go for the Express one.
