Panda Security has a reputation for being a very good anti-virus. If you are suspicious of the email, then go to their web site here
and read about their products.
Choosing an anti-virus is a matter of personal preference, your technical ability and experience, features offered, the amount of resources utilized, how it may affect system performance and what will work best for your system. A particular anti-virus that works well for one person may not work as well for another. You may need to experiment and find the one most suitable for your use. There is no universal "one size fits all" solution
that works for everyone. Another factor to consider is whether you want to use a paid for
product or free alternative
My personal choice is NOD32 Anti-Virus
if choosing a paid for program or avast! Free Antivirus
if choosing a free alternative.No single product is 100% foolproof
and can prevent, detect and remove all threats at any given time. The security community is in a constant state of change as new infections appear. Each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a multi-layered defense using several anti-spyware products (including an effective firewall) to supplement your anti-virus combined
with common sense
and safe surfing habits
provides the most complete protection.
