If you think about it logically, then of course they can conflict as they will all be attempting to scan the same files simultaneously. What apps are you running?

F-Secure, Spybot S&D & Trend Micro. Never a conflict upto this moment

Edit: ("upto this moment" elaborated) no one knows what happens next !

And to be precise, I have Superantispyware too but real time cannot be turned on in free home version for this software. Also, have Hijackthis installed

According to Trend you should have uninstalled the other 2 pieces of software before installing it

Assuming its one of
Trend Micro Internet Security - 2008,
Trend Micro Internet Security Pro - 2008,
Trend Micro AntiVirus plus AntiSpyware - 2008

You need to remove any of the following programs that may be installed in your computer. Having these products installed together with Trend Micro products could result to loss of Internet connection or slow computer performance.

Yeah...please note though, Never a conflict that you know of!

I would still say it's wise to take a professionals oppinion though than just risk it for no real reason, one good quality antivirus like Avast! (which is free) is more than enough to keep you safe!

I only have the antivirus with antispyware installed on my computer. They (departmental store) were providing me the Internet Security with a fair discount but I never bought it though it was on a discount.

Which Trend Micro product and which F-Secure product? Do you actually have real-time protection enabled for all of them for the same things? Check with any manufacturer and they will tell you that there can be conflicts if you run multiple real-time scanners of the same type (running an AV package and an anti-spyware app does not count!)
