It could be a coincidence but it sound like that was a fake update and you may have an infection, if so, then a nasty one.
If you made a Windows 7 Repair Disk when the machine was new, you can boot to this and do a System Restore from outside of Windows to a date at least a week back, then restart it in Safe Mode with networking and scan with Malwarebytes, then manually update Avast and scan with that also. If you did not make the Repair Disk, you can make it from another Windows 7 machine as long as both machines are 32bit OR 64bit and use that. The Repair Disk can also be used to try a Start Up Repair.
If that does not work, you can try a rescue disk like Kaspersky.

Unfortunately no antivirus program can protect against 100% of possible infections 100% of the time. I have had a few The nastiest ones are the ones that start out slowly and some member of the family clicks an OK on something that appears normal and it starts to go downhill from there which is why I say to go back at least a week on the restore.

my 2¢ worth, possible you've got some other sort of nasty (worm/trojan, etc.?). Be aware that a virus and a Trojan are similar, but not the same. Many times, an AV detects one it can't clean, other times, it gets missed entirely. You may be blocked from downloading a cleaner and have to use another macine and make a bootable disk...
If you need to clean one, Malware Bytes (http://majorgeeks.com/download.php?det=5756 ) seems to be the preferred remover, but I've run into a few it couldn't handle. Superantispyware seems able to handle all comers. (Info only. I’m not paid for recommendation. WARNING! FYI, a full scan on mine takes over an hour.) can do the job and you can get it free @:
http://www.superantispyware.com/
among other places.
If it turns out that you need to use it, be sure to update any cleaner prior to running. They just released a new update recently and it changes all the time. Things are in a constant state of flux.
Disable 'restore' after cleaning and run it again (to remove any nasties living there, restart after cleaning) so the nasty doesn't get put back should you later ‘restore’.
The restore thing is critical. May not be your deal at all, but won't hurt anything to try.
