Well to be honest, i don't trust any paid antivirus neither a free one.
If you want to be safe here is how to proceed and why :
- Get a free antivirus like AVG (works fine for live web protection)
- Get malwarebyte anti malware (free edition)
- Get Housecall from Trend
- Get RUbotted (for rootkit)
- Get SuperAntiSpyware (good to remove tracking cookies)
(All Freeware or available in free edition)
Why do i use all this ?
For the simple reason that the virus attacks and the antivirus defend.
What does it mean ?
It means that the antivirus is late by definition, as once your antivirus is updating to refresh its database to add new viruses, you have to know that these aren't fresh virus from the day before, but some that they have identified and solved the day before, but the virus could be out there for months and you may have caught it since the beginning.
SO basically, it is recommanded to scan your computer regurarly (i do it once a week) with several tools which belongs to different antivirus companies.
Most of all, people think they are protected once they paid for an antivirus which doesn't trigger any alarm - Well, here i would be worried : it is not because your antivirus says nothing that you are clean
So basically, investing in an antivirus is not necessary, but being careful when you use your computer with some free efficient tools will help you to remain the cleaner you can.
