I am using Windows 7 Ultimate, and it came with Microsoft Security Essentials. Will it conflict with other antivirus software like Avast or Avira? Thx

Security Essentials is not part of Windows 7.
And yes, it will conflict with other programs.

If you use more than one 'live' anti-virus or anti-spyware program at the same time, your computer may experience decreased performance, become unstable, or restart unexpectedly.

Hoping not to confuse you -- you can have two AV programs installed, but one of them must have real-time on-access scanning disabled at all times and used only for 'on demand' manual scans.

(It's the real-time scanning by two different AV engines at the same time that causes the problem)

Generally speaking though, it's much simpler to have only one AV installed since having real-time scanning disabled on one of them will usually cause it to nag at you, constantly.

Further to this post has anyone tried this as I want to install the Microsoft Essentials Anti Virus as there is a conflict that comes up with my MYOB program that I can't turn off the message from Outlook that says A progam is trying to send an e-mail on your behalf, etc. and having to click Allow for every invoice that I am sending. Which is time consuming and I cannot tell how to turn this message off as the options in the Trust Center are greyed out. I've been advised the only way to stop this is to download the Microsoft AV??
Please help anybody??
