Getting your computer to peak condition is one of the best ways to assure continued good performance from it. One of the many cheap ways to do this is to use optimization software. They help remove apps that you don’t need and monitor your hard drive so that it’s in tip-top shape. You can pick up programs that can do this for free on the Internet.
However, you’ll need to be careful. Hackers and cybercriminals have also figured out this trend and have unleashed malware programs that masquerade as legitimate pieces of software.
A good example of this is the rogue app calling itself “Disk Optimizer”. This particular piece of malware sneaks into your system via Trojans or infected websites. The main thing that Disk Optimizer does is scare inexperienced users – which is why it is called scareware. The main thing that Disk Optimizer does is that it says it has detected problems, usually during a “scan” of your computer – with your computer that may lead to data loss or a system crash.
This is a complete fabrication and just a way to frighten you into buying its supposed “full version” – usually for an exorbitantly high price. You need to remove this program immediately once you detect it. To find out how to do it, read on.

Symptoms Of Infection
- Your computer is acting slow. Disk Optimizer slows down your system significantly. This includes starting up, shutting down, playing games, and surfing the web.

- Searches are redirected or your homepage and desktop are settings are changed. This is a symptom of a very serious Disk Optimizer infection.

Some Disk Optimizer infections contain spyware and keyloggers which can be used to record sensitive data like passwords, credit card, bank account, and social security numbers. The longer you allow the infection to fester, the greater the chance of identity fraud.
