Is your computer running slowly? Are programs starting unexpectedly? Is the activity light on your broadband or external modem constantly lit? Does it sound like your computer's hard disk is continually working?

How do I know my computer get malicious software, spying or virus.
Get an Apple computer, I have been using Apple for 18+ years and have not had a virus.
Good for you, Phil. Although the iOS 7 release had a lot of security holes. Pretty buggy. A guy picked up my phone and demonstrated with a few presses he bypassed the security. Nothing is perfect.
Yeah, no one ever targets a Mac or iPad...whatever.
I love how they tell you to download tools AFTER you have a virus...as if that works. I agree on the Mac. My Mac wouldn't allow the infected link to be clicked on, while my Windows 7 PC had no problem activating then downloading it
Phil, if you have an Apple computer, why are you at this website (other than just starting trouble)? By the way - Apple may not have had as much trouble with malware, but Apple computers are NOT immune to malware infections. Everyone needs to practice safe computing.
Apples get viruses too. Good for you for never having one. You must feel proud.
Received a call today from someone claiming to be from windows operating systems saying my computer is downloading lots of bad programs and they wanted to help fix it! Of course I knew it was a fraudulent call and hung up, but it is distressing there are people preying on others and that the call was timed for for patch Tuesday.
@ Phil, You're delusional. I have had Windows systems and Apple systems for much longer than that, and have never had a virus. It is the "stupid" behind the keyboards...
Also, you may have had one, but never knew it...
Good day sir...
@Phil so why are you on the MS site :)
I've been hearing and seeing a lot of very positive comments about Apple computers. They seem to remain virus free.
I've had a PC for 23 years and never had a virus
yes, Phil, but all of your data on your Apple is readable by all scriptkiddie "hackers"
Normal symptoms of a virus are pop-ups, web browser's homepage changing, search bars added, etc
You'll never get as much sand kicked in your face if you choose to play in the sand box that contains 7.2% of the kids in the playground, rather than the one that contains 91.3%. You also won't have as wide a selection of toys to play with, and those that are available will cost more. The cost to play in the small sand box is more, but some parents see the sand as being cleaner, and worth the premium to protect their child from nasty things lurking there. However, their children don't develop as well the skills of discretion, judgment and differentiation, which are skills they could apply to other areas of their life as well as to using a computer prudently.
I've been using Windows since it was first released and I've had one virus in, what ... 25 years.
