How to temporarily uninstall Avast! Free.

Several months ago I uninstalled my old version of Avira 9 and of Threatfire, and installed Avast! Free Antivirus v7-0-1474 instead. Ever since SpywareBlaster will not come up unless I bring it up in safe mode (Windows XP, SP3). I have been unable to diagnose the problem, and I know Avast! and SpywareBlaster are supposed to play well together. I want to uninstall Avast! to see if that changes things, and then to reinstall it. (I’ll upgrade to version 8 later). Can I uninstall safely and still have all my settings and my Avast! account when I reinstall? What problems am I likely to run into?

Since V. 7 you can save your settings. Look in the settings-menue.

Then uninstall avast! with the uninstall-tool, reinstall avast! and after that just take your saved settings in the reinstalled version.

Perhaps you have to register new. But this is just one click in the Free-Version. No problem!
