here are some things to know if you have a virus..
First, you may think you have a virus, but how do you really tell? Viruses often cause erratic behavior, smiley faces may pop up, your screen may disappear, or your computer may crash. The trigger that activates the virus can be almost anything. For instance, the virus can be activated the minute it is installed. Or it may start its dirty work the next time you start your computer. In many cases, a virus can reside inside your computer in an inactive state, waiting for a certain event (like a certain date) to happen.
From the moment the virus infiltrated your computer to the time that it made itself known to you, you could have innocently spread the virus to others. A very disconcerting sign that you have a virus is when friends call or e-mail to let you know you have sent them a virus-infested e-mail. It can also be transfered via IM's and Peer to Peer's like limewire, Bearshare and Kazaa... SO beware!!!
Now... If you notice any of this CRAPS (lol) in your system.. The first thing you gotta do is STAY CALM.. lol... because people tend to panic when they notice something like viruses... Thats what I did sometime in the best and I deleted some of my system32 thinking the virus is there... and KABOOM!!! I cant start my pc anymore...LOL!!!!
What you gota do is, download an antivirus... My personal reccomendation is AVG (http://free.grisoft.com/freeweb.php/doc/2) Because unlike Norton and PCcillin or Mcaffee.. It's not resource hungry.. It's simple.. lol...
another recommendation is zonealarm.. but... It cost like 50$ for the fulll version... but you can email me for a serial (LOL!!).. anyways...
other programs are:
Anti Vir www.free-av.com
Panda anti virus www.pandasoftware.com
Avast! www.avast.com/eng/avast_4_home.html
My etrust antivirus.cai.com
clam win anti virus www.clamwin.com
and Last but not the least.. KAPERSKY... ( I dont actaully know if it's free or something.. But because it's not that popular, There's less hacks for that program...)
But.. if you dont want any programs.... Try just to scan first...
housecall.antivirus.com
or jsut use free mcaffee virus scan...
but.. remember,, better be safe than sorry!!LOL!!
anyways...
They say only use one anti virus program... I say not... Because... base on my experience... There was this virus that got scanned by Avast but not by AVG.. Well thats just my opinion...
Now... sometimes... your anti virus says they have scanned something.. But cant delete it... what your gonna do is, google the virus name.. then there should be some step by step instructions in some forum... Try that... lol...
anyways... last but not the least but the most annoying and irritating and pissing (lol)
If you still cant delete it.. the last way is to reformat your PC... that sucks I know.. but... It'll surely kill the viruses.. and your files.. LOL!!
And ya... before I forget...
Sometimes... viruses seem to restrict you from accessing the net.. sometimes... it kills your connection or something... now great.. you cant download softwares.. what you gotta do is go to a clean PC.. then download the latest installer from there... now... burn it to a cd or something... then load it to your pc... it shall work... lol
now good luck with you!!!!

One cell can be infected by two virus particles.
Avian flu H5N1 is not able to pass between humans because it lacks the required surface proteins. However it can infect other mammals, and if it infects the same cell as a mammalian flu particle, a process known as Genetic Shift MAY take place, in which the viruses swap genetic information.
A single virus can only infect one cell. Once it infects a cell, it is dismantled to get to the DNA/RNA and many more are made in its place.
One virus can infect many animals, such as Avian flu's being able to infect birds and some mammal such as pigs.
Hope this answers your questions. Feel free to e-mail me for more info.

in theory....yes if they could both penetrate the cell membrane before one lyses the host. don't know exactly what would happen but sure.
