Cannot Get Into My Email Accounts

For the past 2 days i've been unsuccessful in logging into my email accounts and MSN messenger. I'll have to check the new anti-virus to make sure that it is not blocking the use of messenger and email account. The other staff members are having the same problem too so i'm not worried that my accounts were hacked.lol

So all my peeps who are trying to contact me try linking up with me through yahoo messenger because somehow I can get into that messenger but I cannot get into the email. Go figure.lol
