There’s a lot of software floating around on the Internet. Some of them are free, some of them are not, but all of them offer to do something for your computer. Most of the time, you can trust these pieces of software. However, some of them would probably be doing more harm to your computer than good.
For example, there are several programs out there that supposedly help defrag or optimize your computer. They even have official-sounding names – but make no mistake these malware programs are out to damage your system. A good example would be the app calling itself “Win Defrag”.
What this piece of rogue software does is to pretend that it scans your system. It will then “alert” you into thing that your PC has problems. These popups will continue until you have bought the “full” version of the product: The main problem is that these problems are all fake. The program is trying to scare you into buying it. That’s not all. Win Defrag will shut down legitimate scanning programs – opening yourself up to further problems. Also, these “alerts” will stop your PC from being able to do anything. This is why it is recommended to remove this scareware as quickly as possible. To know how to do so, read on.
