Sites that usually save my password now make me enter it?

[Brad]

Websites such as facebook and skype now require me to enter my password but not my username.Could this be the sign of a virus?
Additional:I typed in cmd>netstat -ano and in the state column I see Established alot.I was told by someone that if I see established in the state column I am being viewed by someone...Is this true?

No, not a virus. It might be autosaved, if you don't like it, just set your browser to delete cookies.

your browser has lost its list of passwords, try pressing the tab key with the cursor on your user name

If your using firefox.....it tends to delete history after a period of time...also when the browser updates itself, it could reset everything.

nope not a virus, if you are not using a password manager like lastpass but are just relying on the browser putting the check in the remember me on a site what should happen every 30-60 days is exactly this the cookie that stores the password expires and you have to re-enter the password, if you want a secure way to store passwords then please do try out lastpass. its more secure.
