Avira Pc Cleaner_portable and USB Version

Avira PC Cleaner – a second opinion scanner (Update – English version available)
The PC Cleaner is a scanner which can be used in parallel with other anti-malware products.
It is created for users of other security products who think that they might
have a malware infection which their security solution doesn’t detect.
It works on any PC, note- or netbook with operating system Windows XP SP3 and above. It doesn’t require installation or registration and it doesn’t install any drivers.
The best experience is if you  first deactivate the installed security product temporarily. This way the files will not be scanned twice.
You should reactivate the security product after all is done.

We recommend that you regularly perform a scan with the PC Cleaner, no matter which security solution you have (unless you are already an Avira user).
WARNING:
This product does not replace an installed security product.
Since it doesn’t install drivers, services and other technologies which integrate deeply with the operating system, it can’t provide the same amount of protection
as an installed security product.
The current version is in German only, there are plans to release an English version soon.
We released both the German as well as the English version.

How it works
The product copies its files in a temporary directory and starts by downloading the latest version. This happens only on the first execution, later on, only the differences will be updated (a few kilobytes up to a few megabytes).
It will copy on the desktop two icons:
Avira PC Cleaner – to start the product
Remove Avira PC Cleaner – to remove the PC Cleaner from the disk.
remove;
