Does it hurt to leave a pc on 24/7 and will you get more viruses that way?

I usually shut everything down at night and reboot in the a.m. as I thought by shuting down I would be less apt to pick up viruses or not as apt to be hacked.

    That is a very good question.

    Yes you are prone to pick up more viruses if the computer is turned on 24/7 only if it is connected to the internet.

    It is easier and more efficent to leave a computer on 24/7 because rebooting it each time can make you wait for up to 20 minutes before you can start work on it. This depends on how many programmes are in the start up directory.

    Good Luck

    Actually, if you have it on a UPS, so you don't suffer from brownouts, OK to leave on.

    But, ONLY IF it is behind a hardware firewall, ( FREE uses an old computer, headless!) or a Linksys firewall/router!

    OR, it runs MAC / *BSD, or GNU/Linux!!

    then, it is best to leave it on, as the PSU suffers huge spikes in

    voltage and current when turned OFF/ON.

    Just like the incandescent light bulb, the computer PSU usually fails upon powering up!

    Actually, ALL the "114,000 felon Microsoft Virus Definitions" come from Microsoft systems run by spammers and script kiddies, and other anti-social psychopaths.

    The one clue here is to run AVG, use CrapCleaner, and run anti-malware programs, (all of which slow down the already sluggish Microsoft on the computer), as all these other 811 OSes run upto 50X faster! Search for the free, trial versions, on (yeah, google, Microsoft, MSN, Hotmail, Yahoo all run GNU/Linux and/or *BSD!).

    If you have no firewall or a crap one like norton and your computer is open to certain ports like the internet (http) and email (pop3) it is possible for you to receive a virus.
