Some people recommend to download a free anti-spyware aswell. Is that possible wont the two conflict?
If yes which is the best antispyware which will work alongside avast?

Hello,

in my home desktop, i use Avast as the active antivirus program. I keep two famous antispyware programs installed and occasionally updated -- malwarebytes and spybot search and destroy.

If at times avast detects any virus, usually avast is good enough to delete the virus. But sometimes i also check with Spybot and Malwarebytes. I have not experienced any conflict with having these three programs installed.

You see, Avast is more of the antivirus type that always runs in the background while the computer is on. Antispyware like Malwarebytes and SpyBot Search and Destroy are more of the on-demand programs that run only when you manually start them yourself.

I would suggest you to install Malwarebytes.

It removes all type of viruses and prevents spyware and malware. I have been using this sofatware since 4 years and it works fine.
