Hi,
Yes you can. Ad-Aware Plus itself is an "on demand" scanner, so it will not interfere with any "real time" agents.
You may get some interference if ad-aware scans in the other virus scanner's quarantine folder or if both scanners run at the same time.
But in short you should be able to

and if you have any problems you can always contact the
Support Center and they will be able to help you.

EDIT: If you wanted to check that you are able to use it, then why not download the
trial version and see if you run into any problems
