Styl Skinner: if you don't download illegal software its hard to
imagine you have a 'worm' or virus, it also can come trough mail, but if yo scan
your system, your virus scanner should come up with something, if it dasn't,
just read post #5 |
See my post above about the worm that I had that took out Norton. Worms
are a lot trickier than they used to be. They typically install
backdoors.
You can get viruses (especially worms) from more sources than email and
files. They propagate through shared drives, some through remote desktop
when you connect local drives, and some can even get to you from infected
websites if you don't have proper security. Read up on that type of
information on the support pages of virus protection software.
If you are curious about where pings and port probes come from, check out
BlackIce. It will also allow you to ban IP addresses when they become
bothersome. It also tells you the severity of that action that is
happening. Some behavior that looks like a hack is actually normal
behavior.
Paxx is correct, however. Hackers want to place warez on your machine
and use you as a file server. They typically go after anonymous FTPs on
company servers, however (more space and bandwidth).
