Avast Internet Security saying Key File Expired??

I have Avast Internet Security and I turn on my laptop this morning and it says it has expried. I tired inserting my key file again and its saying its invalid which is BS. Its good till 2/20/2011. My other laptop and Desktop is using same key file because its good for 3 pc’s been working fine since I bought it back in Feburary I get up this morning and this happens. I even tried emailing the key file from my desktop to my Laptop and it still says its invalid. Why are my other 2 pc’s working fine with the same file and just my laptop is messed up?

I guess this was my problem.

I dont know what this is or how I got it but it removed it and I had to restart my Laptop and now its fine. Do I need to take further action or is it good to go now?

If you scan again, does MBAM come up clean ?

Is the license problem with avast! gone ?
if not is your system time / day / month / year correct ? if not adjust and reboot

have you tried avast! repair ?
For a repair of avast. Windows, Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button from the pop-up window, scroll down to Repair, click next and follow.

Yes I rebooted my laptop after the infection was removed malwarebytes prompted me to so I did. When my laptop started back up everything was working as normal. I also did full system scan with Malwarebytes and SuperAntiSpyware and both say its clean. I been getting a windows pop up screen on boot-up for the last 2 days that says outlook express can compress files to save disc space and I just exit out of it. I dont know why i get this I don’t even have outlook express on my laptop as far as I know. I use incredimail for my email. I dont have Microsoft office of any kind I use openoffice on it. What could cause this pop-up?
I also did full system scan with AIS and says no infection found so I guess its all clean.

Outlook Express follows with XP so the popup is normal, just click OK next time

Please Don’t Use Incredimail http://www.spambutcher.com/press8/627181/

So should I use outlook express or you recommend something else? Thanks for your help.

Outlook Express is fine or upgrade ( it is free ) to the newer Windows live mail

Thanks for you information. I have my outlook up and running now and I deleted my incredimail.
