Hi,

I was removing from my PC the installed Avira Free Anti-virus software via the Control Panel when this error message popped up.  

I was wondering why it did when no other software or installation was running.

Please help me since I needed to install a different brand of antivirus software.  

Thanks a lot.

I am trying to uninstall the Trend Micro on my computer because my license has expired and I am not renewing my subscription at the moment.

Through the Control Panel, I uninstalled the program and my PC prompted me to restart it which I did 3 times. However, I saw that it was not uninstalled successfully. I tried to uninstall the program through the Programs menu on Start but then again, I was unsuccessful. I know this is not a problem with the application because I was able to uninstall the same program on another computer without any issues.

I have an anti-virus on but I only noticed this virus when I made a decision to scan my computer externally using a network. What can I do to get rid of Conficker.C virus without the need to re-format my system? When formatting is the final option, if I transfer the file from the infected disk to another hard disk, will the clean disk be infected as well?
