It must be better to use a "trial version" of any "Anti-virus" software before you could buy it. Every leading Anti-virus softwares gives you the trial version of the software, which you can use upto 60 days or less. The trial version gives you the most features which are in the premier version but, still you may not get the "Advanced features" on it. You want to make sure whether this trial version is running smoothly on the background of your pc and detecting threads/viruses from external files and devices.
Here are the best Antivirus Softwares:
- Avast Antivirus
- Kaspersky Antivirus
- Avira Antivirus
Even though there are other Antivirus available, I am just suggested you the best. I would simply recommend you to go for Avast Antivirus which is cheaper and works better in background. I have already tried these "Anti-virus softwares" before, and also more like Escan, Mcfree, AVG, Cis Premium. Now, I am stick with "Avast".
"Avast" is a free antivirus software and you can get the paid version too, which will have great extend in protection. It has a simple UI which features Quick Scan, Boot-time scan, Browser Clenup, Mobile Protection, Software updater, Secure line, Rescue Disk, Access Anywhere, Sandbox, Mail shield, Web shield and much more. These features will give your computer the best protection in offline and online. You can also simply update "Avast Antivirus" and get secure from latest threads. If you're having trouble with your "Avast Antivirus" you can simply contact the technical support centre of Avast. You can download the trial version from the below link and it has 1 year validity! And after that or after you have satisfied by the performance of Avast Free Antivirus you can upgrade to the premier version.

Other Antivirus Softwares are also good and efiicient, but please use the trial version before buying the premier version. Keep your computer safe from hackers, virus, spammers, etc.
