Help need: Whats going on

Recently i had the trojan flush.a on my comp for many months and my av
(avast did not pick it up) but after have alot of probs with website links
getting re-directed to a single blank page with same ip in the address bar i
tried an online scanner ( symantec) and it returned with this trojan.

i removed it as per instructions, but there were 2 steps which i did not do
because they didn't apply to my comp.

Since ive got rid of it, ive been having major problems with my internet
connection, i seem to be just losing my connection at random times of the
day and when im surfing the net, and click on my next favourite or type in
an address my connection becomes un-responsive and reloading my browser
gives me the "page can not be found error message" www.xtra.co.nz

the only method ive found is to completely reboot my router / turn it off
and on again and re-set my comp and go through the process of trying to
connect back on.

I have a feeling its something to do with the dns settings, on my comp or
router left behind because of the trojan in which symantec says it alters
the comp's dns settings, in the registry. as per instructions by symantec
ive deleted the registry keys located.

Even now after only 2hrs of connectivitly its just droped off, but yet i can
still log into msn messenger and check my emails, (this does not always
happen tho, i when i start my comp in the morning nothing will work) but
when i use I.E or Firefox i get the page can not be found error, please
check dns settings.

My router has been set to auto discover dns settings.
Im at a loss as whats going on, i no the only way to sort it out completly
is to reformat everything and restart, but i really don't want to do it
again.

Any suggestions on what could be causing my connection to just drop off and
how to fix it?

Cheers in advance

Hi,

My personal view is to just restore a clean backup (if you have one),
or re-install from scratch.

I tend to think that once a PC is 'dirty' it is always going to be
suspect and / or potentially unstable.

If you have something like Ghost, then it only takes 10 mins to do a
full restore anyway so why not? If you don't have a backup of the
system (data is fine, but you need to restore the system itself), then
re-install from a clean format, and then create a backup immediately
and then at least monthly if not weekly.

There are plenty of free backup solutions out there if you don't have
Ghost or something similar already. Others here will probably offer
opinions on the best open source / freeware options if you want them
(or even if you don't want them!)

HTH,

Alan.

You could look into resetting your XP TCP/IP Stack.

Turn off the Services you don't need like caching DNS queries.
