This is from your log: [quote]Windows version: Windows Vista (TM) Business, Build=6000, SP=""[/quote]So, first of all i suggest you to install [url=http://technet.microsoft.com/en-us/windows/dd262148.aspx]SP2[/url] as soon as possible. Besides, you should uninstall Avast! antivirus before install Kaspersky antivirus. As for your log-file, according to it your system looks clean.
