I own Yahoo Internet Security and I wonder if i.e. satisfactory protection. Is it possible to put CA Internet Security on while running Yahoo Internet Security. Or is it possible to run Panda internet secuity while running Yahoo Internet Security.
Answers:
The use of 2 or more anti-virus programs at matching time can do foremost conflicts. The 2 scan engines will be at odds respectively other to scan every profile that you read, write or execute which can mete out a trunk computer slowdown. For alike source, using 2 A-Vs can produce you to enjoy smaller quantity protection from the different malware, not more.
(Using an anti-spyware beside an anti-virus is well-mannered, however and is recommended)
Internet Security Suites such as you are refering to will mostly include an anti-virus, an anti-spyware and a firewall.
IIRC, the Yahoo suite is in actual fact re-branded CA apps.
Good luck.
As long as you do not hold more than one anti-virus installed on YOUR appliance you will be fine.
