One System Care is a new fake system optimization tool. This is the malware program pursuing the aim of tricking users into thinking that their PC is full of system errors and bugs. The program penetrates to PCs without permission and then runs the scan with every system startup. It also modifies your system registry in order to be launched automatically each time you turn your PC on. This means that once Windows OS is loaded successfully One System Care would come up in front of you, without you clicking any of its icons or shortcuts at the desktop. The application continues implementing its malicious plot. It initiates the fictitious scan of your computer which is then followed by the horrible report regarding various sorts of hard drive and system problems supposedly identified by One System Care during such scan.
