Default List of common things viruses screw with

What are some of the most common things that viruses attack? What functionality do you check on when making sure that a machine is fixed?

- broken file associations
- start button, start menu, task bar gone
- add/remove programs will not populate

I had one today redirect internet traffic with a proxy setting in IE that shot it back through local host. made internet not work once virus was removed. Easy fix though.

Internet settings, connections, disable proxy and re-enable automatic settings. All it did was set a proxy that directed traffic to 127.0.0.1:5555

This is another reason why I like to infect VM's so I can play with strange post infection problems and get the computer running correctly again.

Sometimes I will infect a VM fix it infect it with something else. After doing this a few ties other problems will show up that would not normally. I don't always start with a clean snapshot.
