How will Fedora or Linux increase browsing or downloading speed? That is not possible.

download speed is not increased like that but yes in windows a part of bandwidth is reserved for windows update and stuff where linux don't keep any reserved bandwidth apart from that linux users are smart enough to by pass proxies
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

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...

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] ....

I tought that Linux was Virus free,because all executables are files in Linux and need our permission ro run them...

guru dont worry about virus and you can use your ubuntu without any issues

Thanks vibes i can browse now without any issues,happily in Linux.

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.

I havent experienced any difference in browsing speed in Fedora (i have a dual boot FC8/win xp sp2)
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... )

There are Linux viruses too ...but they r rare ....

The Major prob like i highlighted is that Windows viruses will hibernate in Linux .... i know not how ...and will effect ur Friend's windows comp [not urs] thru ur mails and Portable Pen drives/hard drives

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. :surrender:

hold on ... tell me how to use full bandwidth in windows.. how to set quality bandwith set to zero???

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.
