 apart from that we really don't use different firewalls so there are no barriers and please don't ask about any virus on linux... Linux users hardly care about virus  | |

Rep Power: 10 | Windows reserves 20% of bandwidth for something called Quality Of Service(qos)... Which affects browsing speed(not downloading)... This option can be disabled or decreased to 0... And yeah very less chance of virus threat for Linux... |

| Fedora Part of bandwidth is reserved by windows for "quality maintenance " of the connection ...but it can be easily changed not to do so in order to get full speed..... I am a Fedora core Power user and yes ..unfortunately nowadays even Linux is effected by viruses .... One even disabled my transcend flash drive  Security Tips for Firewall Fedora has a built in firewall ...its more powerful than Window's default firewall Access it by opening the terminal type in: system-config-firewall You will find the firewall setting also somewhere in the Gnome or KDE menu Security tips for Anti-virus Use (free) clam antivirus [the most popular for Fedora ] To install clamav: 1. open a terminal 2. su - to become root 3. yum install clamav 4. answer with y, if yum asks Clamav Anti-virus for Fedora Unless you r stubborn and run as root ...the chances of viruses attacking fedora are remote . But it may attack ur friend's windows sys thru ur mails or portable devices ...as most windows virus dont run in Linux distributions ... Anyway there are few that do some damage [like it did to me] .... |

Rep Power: 2 | I'd like to add a point to what shadowcon already mentioned. Not only fedora, all the distributions come with their own default firewall to protect every user. And all those default firewalls are mostly activated by default without the end user's permission (don't you think it's a pain to install and activate a firewall, once the OS has been installed). As far as virus is concerned, there is a possibility of various kind of attacks under linux too. I always advice to turn ON updates, if it's not enabled by default. And never run ANY application as a root, unless it's required. |

Yes, Fedora has its share of problems too (like any other OS) but you are far less vulnerable than Windows. Turn off services that you do not need (web server/ mail server / ssh) Disable ssh for root. create an unprivileged account and add it to the sudoer's file and run sudo commands whenevr you need root prvileges to do something (a la Ubuntu style) (SOrry, i;m just rattling off things top off my head, i'm typing this at work... ) | |

Rep Power: 2 | There is a virus scanner for linux though called clamav short for Clam antiVirus. It is not a realtime guard like Windows antivirus programs meaning you will have to manually run it from the commandline to scan a file or directory. Useful if you're worried about any infected pen drives and want to check them for viruses in Linux where Windows viruses can't run. Edit: Oops..ShAdOwCoN already mentioned clamav in a previous post, seems I missed that.  |

Rep Power: 0 | solution to reduce 20% reserved bandwidth to zero allocated to windows 1. Make sure you're logged on as actually "Administrator". Do not log on with any account that just has administrator privileges. 2. Start > Run > type gpedit.msc 3. Expand the Local Computer Policy branch. 4. Expand the Administrative Templates branch. 5. Expand the Network branch. 6. Highlight the "QoS Packet Scheduler" in left window. 7. In right window double click the "limit reservable bandwidth" setting. 8. On setting tab check the ENABLED item. 9. Where it says "Bandwidth limit %" change it to read 0 (ZERO). 10. Close gpedit.msc. Effect is immediate on some systems, some need to re-boot. |
