Hello chako, Please tell me what model of the Inspiron that you purchased. The program that you ran, is picking up several normal everyday items that we see on  everyone`s pc`s. DO NOT worry about this. Anytime we download or install software you will see registry irregularities, usually more from uninstalling programs. Some of these will be cookies from websites you have visited and temporary internet files. The security vulnerabilities may come from needing Microsoft updates. The first thing I want you to do, go to the start button, all programs and Microsoft updates. Get any of the Microsoft updates that your pc needs. Make sure you have an antivirus program on your pc and it is updated and running. The one unnecessary start up item, is something that comes on with your pc and may not be necessary to the start up. After you have done this, come back and we will discuss your next steps.
Hi anyone, I just purchased Dell Inspiron Window 7 from Best Buy on Aug. 3, 2012.    I paid extra $100 to set up to use.   Now, PC Power Speed says 402 errors in my PC and Microsoft Tech Support verified them on Aug. 5.   Dell Tech Support told me that many softwears are conflicted each other on Aug. 6. Dell Consumer Service Store diagnosised 1 unnecessary starting item, 145 registry irregularities, 13 repairable security vulnerbilities, Internet setting may not be optimized for best performance, 149.31MB of system file clutter in 344 files, 24.02MB of Internet clutter in 563 files. Do I have serious problems?   Where do these problems come from?   What should I do about these?    Need anyone's advise. Chako
