How to remove winsysapp.exe, commgr.exe and winalerter.exe

I am unable to delete winaleart.exe from Program files->Window alert and commgr.exe from Program files->Windows common files as command prompt shows file does not exist but while scanning it shows infected files. I have stopped these processes in task manager and have unmarked them from start up list.Using command prompt I have stopped, and deleted C: Recycler from c drive. I want to get rid of this two files. Please let me know how I can delete these two files from my computer. Thank you in advance for your valuable suggestions.

In such situations when your system is infected with such malware do not delete threat manually and try to delete them using Anti-malware or with the help of support team.

I have downloaded and Installed Microsoft security essential on my system and did full system scan. Now I do not have nay problem. But to have only Microsoft security essential on system is enough or I need to install any other Anti-virus?

Microsoft security essential is a Microsoft anti-malware program and the special thing about Microsoft security essential is that it does not require too much system resource. Remove any other anti-malware products that were already installed on your system. After removing the other anti-malware reboot your system and see to it that windows Firewall is ON. Using control panel you can check the status of your windows Firewall. You do not need any other anti-malware program with Microsoft security essential.

When you install Microsoft security essential then you are having Anti-malware and Anti-spyware both and your system is protected against this threats.
