Hi, janardhan. Welcome to 2-Spyware.com forums!
Are you really sure that the
install.exe file drops parasites on your computer? This file can be used by thousands of different programs including legitimate ones and malicious parasites, so you cannot delete every its instance.
Which symptoms do you have? How does your system behave? Please provide me with more details regarding your problem. It would be even better if you would
download the HijackThis program, scan your system and post a fresh log here.
