I use a firewall too.
People will visit sex sites & warez sites & sites with stolen music,etc.
Lots of seemingly safe sites will add tracking cookies & other crap to a computer.
I read lots of posts about being infected with popups & spyware & viruses & things not working right.
That used to happen to me until,after years of learning to avoid such things,my computer runs good with only minor glitches.
Which are easily fixed by me after using Error Reporting or using Google.
I recently added 256 MBs of RAM.
No problems after doing it because the clerk was a knowledgeable person who opened up a computer on the shelf like mine & pointed to the slot & said put it there.
I did & it worked fine.
Some people delete programs without using the uninstall program & lose shared dll files.
It's a good idea to ask a few questions before doing anything to your computer at all if you have never done it before.
Lots of people are new to computers.
They do stupid things.
(I used to do stupid things.)
I learned to ask questions & use Google.
I guess I'm just saying to safeguard your computer with a firewall & antivirus & antispyware & antiadware & look before you leap into a situation that will mess up your computer.
Don't be afraid to ask for help either by using a forum or doing it yourself by using a search engine.
That's all.
Ranting & venting is over for now.
I feel better now.
I hope this all helps someone to maintain a smoothly running computer.
Don't get frustrated.
Learn from mistakes.
