hi,
I have Norton internet security in my PC but i still receiving message from
th PC that i have virus.What can be the problem or how can i do to remove
them.
On-line scanners are the most unsafe and next to useless. Because by the
time you've started your infected Windows and connected to the
Internet via this infected code base, and start to look for scanning sites
through infected DNS, you are almost certain to have the malware
perfectly positioned to overrule your attempts to clean it.
What happens if active malware is found? Don't expect that the on-line
scanner will do anything about it. Most of them are just just marketing
tools for selling you their products. Quite often, malware removal is far
from easy. Sometimes a resident AV can deal with it in Safe Mode.
David's Multi-AV is safer, because you don't have to be online to use it,
and it can be used in Safe Mode.

It's safer still if you can avoid running any code from the infected system
at all, and that can be done by working from Bart CDR boot.
But that means having a clean system to build the Bart disk, and more to
the point, a fair bit of effort and technical fiddling.
