If your ram is less than the recommended amount, you won't be able to install with the graphical installer,
but you might be able to use the Alternative cd, where you can use a text based installer - that uses less memory.
If your machine does have plenty of ram, you might want to try running Memcheck (which is also an option from the live cd, see below)
to just make sure your ram isn't failing.

- if your pc doesn't meet the Ubuntu prerequisites, you can try:

xubuntu http://www.xubuntu.org/get
lubuntu http://lubuntu.net/blog/lubuntu-1004-now-available-download

No. Ubuntu is not the source of your problem.

Apparently this virus infects routers, which would explain why your newly installed system can be affected. In that case you need to restore the DNS settings of your router (you may need to reset it to factory settings, depending on how configurable it is). You'll have to consult your router's manual for instructions on that.

with my cisco system router which is a linksys all you have to do is unplug the internet then shut off the power for a minute then power up wait for the light to stop blinking then connect the internet back up let it reset and it is good to go . may work or yours !
