Anti-Virus software for Windows 7 - recommendations?

Can anyone recommend Anti-Virus software for Windows 7? I have used McAfee for a long time and was happy with it. But they are now quoting a very high price for renewal and I want to switch to something else.

I am not insisting on a free version of the anti-virus, but have no issues if the best one is free to use. But I am happy to pay a small subscription fee if the software is worth it.

Thanks in advance!

I've been using Avast free edition for years.

Avast works for me, bit "naggy" but seems efficient enough - and its free

MalwareBytes sometimes spots things Avast misses (like PUPs mostly) so I run that once a month too. Also free

Another thumbs up for Avast free.

Best antivirus - don't visit porn sites xd (or open any questionable sources)

Eset's NOD32 is pretty good.

Thanks for the advice.

Has anyone used Kaspersky? It is not free but reasonably priced. And the fact that Barclays gives this free to its customers would suggest it is perhaps better than the free ones?

Have used Kaspersky for some years. Used to have the ISS purchased via my bank but now use antivirus only, bought quite cheaply on eBay. I find it unobtrusive, easy to use and doesn't slow the computer down. Would recommend, especially as it usually scores well in tests.

I have noticed some sellers on eBay seling a one year subscription to McAfee for less than a tenner.

Any thoughts or good/bad experiences with any of these?

I use Avast free but I would also recommend Kaspersky as when I did use it I found it slightly better than avast and a good price too.

Another thumbs up for Avast free.

I use avast on my iMac:thumbsup:

Kaspersky Antivirus 3 PC, one year license can be bought via eBay for circa £12.
