My sister was conned by Trojan.win32.agent.azsy that pop up to tell her that her PC is having multiple security issues that need to be handled by Personal Antivirus. So she got it installed to the PC thinking that this would help in cleanning up the threats. It also encourages her to purchase and installed licensed version of Personal Antivirus, which is a rogue anti-spyware. Infected computer exposed to outer threats by opening up illicit connections that facilitate remote access to the compromised computer and may enable further manipulation from the outside.
After the installation of Personal Antivirus, there was a continuous alert pop up saying that the PC was infected by 'Trojan.win32.agent.azsy'. So I googled 'Trojan.win32.agent.azsy' and tried to get it of threats.
Solution :
1) Download 'Spyware Doctor' from http://www.pctools.com/spyware-doctor/download/
2) Run the downloaded Software.
3) When the scan finishes, it would show all the the infected files, cookies and also entry in registry.
4) To clean it up you need to purchase the software online.
5) Opting not to purchase it, I clean it up manually.
