Can anyone help me please, thanks…

Do you use any other antivirus software? or did you use any other before you used avast?
Do you use any security software? (antispyware,firewall,…)

which is your operating system?

yours

I won’t worry that much… or anything about that… just verbose of the logs.
C:\WINDOWS\TEMP_avast4_\ is the folder of avast temporary files.

Then the question is why is it error? whats the cause? i didn’t use any antivirus before avast because the os i use winxp pro sp2 is just fresh install a couple of days ago. Aside from avast, i have spybot s&d. Teatimer and resident IE helper is active. But as you said i don’t worry for that, so it means no problem?

It means no problem at all.
Error trying to handle a file and temporary avast files.
Files that can’t be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.
Also, the packaging of the file could have some error, or use a non-standard pattern…
