This evening avast! has updated itself and now it doesn't work well.
Double-clicking on avast!Antivirus icon the splash screen freezes and this message pops up:
Unknown error.
Program cannot set property into main Storage.
To get rid of it I must use the Task Manager.
Then I see the window of avast! and I think it could scan the system (I tried it only a few minutes) but its reactions are very slow: e.g. to exit I have to wait about 20 seconds after my click on exit.
Having read in another thread to check the sys drivers in windows\system32\drivers, I did it and, being the time stamps of the creation date different, I overwrote them with those of the avast4\setup\inf directory. But the problem is still there.
What can I do? Please help and forgive my English.
Thank you.
Windows XP Home SP1.
