Yesterday when I scan my system with Prevex 3.0 it shows infected files 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.
