Trend Micro Antivirus – How to Re-enable Base Filter Engine

You just got this message "Your Personal Firewall has shut down". After restarting windows and "Trendmicro Internet Security" software a same message persists. How do you restart a "base filter engine"?

You have rebooted, restored back one month, turned Trend micro on and off. Can you please verify and set specific Trend Micro services to automatic. Are you using Trend products for both firewall and anti-virus?

Click on your Windows "Start" button. Click "Run" and then type in a run box "SERVICES.MSC". When a services window appears, look for "Trend Micro Proxy Service", "Unauthorized Change Prevention Service" and "Personal Firewall".

Double click on a startup type: select “AUTOMATIC”, click "apply" then OK. Set only those services that you see to Automatic, and also try to start them. You can try to manually start them and see if they do or if they error out.

In services you should be able to start those services that you set to automatic. Start them up and then try to update Trend. If you still get errors you can reboot your computer and see if that resolves them.

If not, what version of Trend are you using ie. 2008, 2009, 2010, etc.? You can set "unauthorized change prevention service" to automatic too. Do you get those errors when you just try to enter Trend Micro?

I recommend rebooting your computer now that those services are set to automatic and also running a repair on Trend software if possible via Add/Remove programs in control panel when you have time.
