PC Maintenance and Security
I choose four tutorials within the PC Maintenance and Security workshop.
a. Uninstalling unwanted applications
a. Uninstalling unwanted applications
I learn from this tutorial that I could go to the control panel and click the remove button to get rid of the duplicated software I don’t want to use. The information surprised me is it could be so easy to deal with the downloaded trash from Internet. Since I used to try to delete some software, but it always show the disc is writing protection so I couldn’t delete that software. But now I know how to do this easily and quickly.
b. Explain cookies
I learned that cookies are very small information can be stored into hard ware. And there are three kinds of cookies, they are “persistent cookies , session cookies, tracking cookies” Although most of cookies are harmless, but the tracking cookies can uncover your information to some advertisement company, and unless you delete the cookies from your computer otherwise the advertisement company will get your personal information.
c. Using pop-up blockers
c. Using pop-up blockers
I learned that in both windows and firefox I could control the pop-ups, since I often feel busy when I open some pages but some pup-ups also jump out. Now I know I could go to my windows tools , and click them and chose pop-up blocker. For some websites I don’t want to see , I could also add the sites to block. And there is also filter level, the best is to choose medium level, then some pop-ups will not jump out again after that. But if I choose high level filter, then most of websites maybe blocked , or lose functions.
d. check PC maintenance checklist
I learned that the PC maintenance checklist is composed by several parts, including check for Microsoft updates (manually too), update your security software, run disk degragmenter, update your most-often-used software (patches at least), run your clean-up utility clean all the junk in your computer you don’t need, and design back up sytem to protect from losing any documents, pictures and videos. The thing surprised me is that I don’t know the PC maintenance checklist is so long. I just think it will be very easy to maintenance, since those people help me to main my computer will only use a few hours without touching the computer, they just click on some buttons during the process then leave the computer alone there. But now I understand there are so many processes for me to maintenance my PC security.
