Problems with Avast

I use Avast Antivirus and most of the time it works ok, now and again it decides it wont work, I get the memory test and then nothing, I uninstall and reinstall and then it works, until tonight when it still wont work, does anyone have the same problem.

I am using Mozilla Firefox as my browser and Vista Business

Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?

As what you mention is often associated with conflict, either with another AV or remnants of the previous AV.

I downloaded Avast as soon as I bought this computer, McFee was installed but I got rid of it by using Add and Remove Programmes

I think you need to take another step to ensure it is all gone.

You didn’t say which McAfee version, so here are the various tools:

2007 version - http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

Also see - How do I uninstall SecurityCenter? http://ts.mcafeehelp.com/faq3.asp?docid=71525

Thank you for your help, I have used the removal tool, hopefully my problem will have been resolved

You’re welcome, hopefully it will resolve it.
