c:\program files\DivX\divx player\pS2Xx.ddc (Backdoor.Bot) -> Quarantined and deleted successfully.

I have run a full scan twice since and been clear both times.

My pc appears to be running normally,no freezing or problems with start up etc.

My question is; is it safe to leave the file in quarantine or should i delete it.

Apologies if this is a very basic question but i dont want to be complacent even though i seem to be clear

Thanks

It is safe from infecting you in the Quarantine folder. Typically it's best to leave items for a couple days that include reboots to ensure any such file is not a false positive or some other issue. If nothing wrong is noticed on your PC after a couple of days then you can empty the Quarantine folder.

Windows Service Pack 3 has been available for a year and contains several Critical Security updates plus performance improvements you need to start Internet Explorer then go to Tools then Windows Update and download all of the available updates.

Also you should enable Automatic Updates or at least be notified that Updates are available.

Go to Control Panel then Automatic Updates then select Automatic (recommended) or at least Notify me but don't automatically download or install them.

Go to Secunia Online Software Inspector then run it to see what other applications are vulnerable:
