Anti Virus not working, might be virus and cannot run scans

I am having trouble with NIS2006. The live update seems to be messed up and not working correctly. I cannot get the free scan going online with TrendMicro as well? Is there a way to scan and see what is going on virus wise another way?

A lot of malware will block Security applications (and access to websites).
Start with these two.

Load Superantispyware and click the "check for updates" button.
Re-boot into "Safe Mode" (tap the F8 key during boot cycle and select 'Safe Mode'

* Start Superantispyware.
Click the "scan your computer" button.
Check "Perform Complete Scan" and then next.
Superantispyware will now scan your computer and when its finished it will list all the infections it has found.
Make sure that they all have a check next to them and press next.
Click finish and you will be taken back to the main interface.
Click "Preferences" and then click the "statistics/logs" tab. Click the dated log and press view log and a text file will appear.

Also check your HOSTS file to see if it has been modified by malware.

You can use a HOSTS file to block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and even most hijackers. This is accomplished by blocking the connection(s)) that supplies these little gems.

Windows XP = C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Windows 2K = C:\WINNT\SYSTEM32\DRIVERS\ETC
Win 98/ME = C:\WINDOWS
