Which Antivirus For My 64 Bit Windows 7 Ultimate ??
As i Had Quick Heal Total Security 2010 64 bit .
But After Trying to Install The Quick heal It shows error and Does not Install completely.
Is There Virus Which Is Disallowing The Antivirus to Install.
Any solution To this Problem required As early as possible .
Or else Please suggest any other 64bit antivirus which may be installed with ease .

The problem is that there just aren't that many dedicated 64bit antivirus programs (yet). However, Windows 7 has excellent backward compatibility with most modern 32bit programs.. I would suggest Microsoft Security Essentials as a free solution.. Try it, you'll like it!

Microsoft Security Essentials

Another strong vote for the best anti-virus which is also free:
Microsoft Security Essentials Virus, Spyware & Malware Protection

Agreed with both suggestions above and MSE runs as a 64-bit process natively so that's a plus.

 

[neeraj]

agree with everyone...
MSE is light..free..and a plus point darician said that it runs as a 64bit process...

try MSE u'll not regret it..!
