ARO 2013 for speeding your PC, just as the job done by CCleaner which cleans your registry, junk files, and temporary files and thus speeds up the performance of your PC. It will scan your PC looking for junk files, broken or missing registry keys and security vulnerabilities. The scan will take you through everything from browser temp folders, the recycle bin, to old error logs, shortcuts, cached files, and temp system icons. The registry cleaner runs with focus on search and destroy. The system scanner is a nice feature, but for some protection. You will get 50 fixed on the trail version. It has enhanced cookie detection mechanism. ARO gives the ability to clean up persistent cookies that would normally stay in a browsers subfolder until they are manually deleted or the persistent cookie file was set to expire. The improved baseline security scan is designed to detect the existence and up-to-date status of antivirus, antispyware, and personal firewall software.
