As the use of Microsoft's new beta antispyware increases, many users are reporting this error. Here are some hints for working around this error.

So you are receiving the classic 101 error too? It's an odd error that is caused by several things... usually it because of a permission issue. An update or a reinstallation will usually work.

Here's how to Update:

1. Logged in with admin privileges, open your Control Panel
2. Select Add/Remove Programs
3. Select Microsoft AntiSpyware
4. Click Change
5. The Maintenance Wizard will open. Select Next
6. Click Update Microsoft AntiSpyware
7. Select Install and the product will install
8. Click Finish

If that doesn't work, you can uninstall it completely from the control panel and reinstall:

You can try killing the program and restarting it:

1. Hit CTRL-ALT-DEL -> open task manager
2. Select gcasDTServ.exe
3. Select End Process
4. Restart the antivirus program

The newsgroups have also been suggesting making sure your DCOM service is started:

1. Click Start
2. Click Run
3. In the textbox enter C:\WINDOWS\system32\svchost -k DcomLaunch
4. Click OK
