Restart your pc and run setup again. If it fails download it again. Avast is better than avira because of real time shields and Webrep. Detection rate has been improved.

Have you tried to use net protector? It is really a good anti virus and easy to use.

The problem is not your recent anti-virus but some of your system files may be missing. First try reinstall operating system and necessary drivers. Then find some free anti-virus link AVG or Avast from reputed download sites.

I want to share to you, try Kaspersky its a very reliable antivirus sure keeps your system safe

HEY , i am using ESET NOD 32 Antivirus . The best thing about it is that it is free and it has caused no problem till now .My advise is that you shall go for it .

Try AVG, it is simple and free. It works well

Go for the Avira without any hesitation as I'm using it since three to four years.

Malwarebytes Anti-Malware Free is a great product.

For me, Avira would be best! It works just fine!

I always go for a lightweight and reliable one - ESET NOD32.
