I name like Free antivirus product from SmartPC.
Edit: When I try to purchase it it display like this.
Free for a year?
I too am confused it is permanent free or free for 1 year.
The site has a comparison table which mentions free AV too. I have installed free version but I am able to enable/disable paid features which are shown for paid AV in the comparison table.
I have installed free version. It looks exactly like Bitdefender. Tested few malware not much but the detection seems the same as Bitdefender. This is 1 licenced product which seems to detect the same as original product. Testing with few more malware will show if the detection are same.
The email I received mentioned requirement 256MB RAM & during install it mentioned 1000MB physical memory required, install anyway with Yes/No tabs. I have 512MB RAM & its running light here on XP SP3 32 Bits.
Attached is the screenshot of the main GUI & Comparison Table.
