Answer 3

I would suggest that you get Avast. It is free for personal use.

Yesterday, my free anti-virus caught a trojan virus.

To ensure that the virus caught is not a false positive, I upload it to virus total web site to check.

To my surprise, all the big names in Anti-virus industry cannot detect the trojan. The one that detect the trojan are mainly the free version.

Avast boot scan in Windows safe mode is the most effective way to get rid of stubborn trojans and viruses that keep coming back to haunt you.

These trojan and viruses hide themselves in system restore folder and many anti-virus programs cannot get rid of them. So whenever, you restart your PC,

the viruses are restore back by WIndows.

Avast boot scan help to get rid of them in the system restore folders and ensure your system are clean.
