a network configured in a bus topology.the biggest problem is theres a physical problem at one computer the rest of the network can no longer communicate.what would you suggest to your client to remedy this problem?

Sounds like one network card is trying to take over the whole bus!..... Other cards will wait a random amount of time after a collision of data and try again, only to encounter another collision!
If you know which machine is causing the problem, then issolate it to confirm this.... otherwise it's a process of elimination!
It is probable that the network card has gone faulty!.... Try unseating the suspect card from the machine and gently flex the board slightly before reseating it!..... This sometimes works, but otherwise replace the card!
Have you checked all connectors and cables?..... T-pieces can often be a cause of problems!..... Check systematically along your bus using cable known to be working, etc...
The only other cause that comes to mind, is maybe there are too many computers on the bus all trying to send high volumes of data..... Collisions will occur almost continuosly and hence the Network will grind to a halt!

I'd suggest changing the network topology from a bus to a star topology. Have the client invest in a decent switch to increase the number of collision domains. That way, if one computer. goes down, the others won't be affected.

Sara is right in saying that it looks like your computer notifying you but isn't your computer. Windows doesn't notify of viruses because there is no anti-virus built into it. Almost always, a notification that pops up and doesn't come from your installed anti-virus program is an attempt to gain access to your computer - best thing to do is shut them down using your computer controls and NOT the controls on the window because they can be reprogrammed to install viruses; yes, this includes the X in the top right of the window. Either: Hold the Alt key down and then press F4... OR Right-click on the window's icon in your taskbar and choose Close. For goodness' sake, don't follow Greg's advice to the letter!! Note that some of his lines end in ... He mustn't have known that when a "word" is too long, Yahoo shortens it and puts ... instead of the rest of the "word." You can follow the advice for ones that don't end like that, though. I'm of the same opinion as Golfer - it does sound like this thing has been there from the beginning - was this a new or second-hand computer? Makes me wonder if someone was playing around at the shop and didn't know that they shouldn't allow that thing to install. Either that or the program you mention has a very similar name to a well-known, (or perhaps I should say "infamous") virus program. I suggest using Malwarebytes and Kapersky as has already been suggested and there are some links in my profile that could be helpful too; one of them is to a virus cleaning guide at Major Geeks - not quite sure if I remember seeing someone had given you a link to the Bleeping Computer one and they are both good. Sign up to one of the forums linked from my profile if you still need help after cleaning your computer with one of those guides - the people who help at those forums are good. If you post at Major Geeks, I know the rule is post, then wait - don't post to ask if someone has seen it yet because it's in a list and they'll get to you in order of oldest post so adding a new post drops you back to the bottom of the list.

Or linear topology. Lets say that you have 10 PC's on a long single line. the middle PC fails. all PC's on the left of the failed PC cannot communicate with any PC on the right of the PC and vice versa. BUT PCs on the right can communicate with each other. This topology is called 10 Base T on BNC.
Forget drivers etc . The break in the cable stops all.
Simple terms, a road gets blocked due to a crash.
Cars on each side can talk to each other but not across the accident. The road is the linear line.

change to a star network or a fully meshed network

If your computer is not working properly while you are working on it, it could be a problem with device drivers, hardware or software.
