The rule number one of business also applies for computers: protect your investment.

Assuming you have spent a great deal of money on a computer and its software components, what's left now is to make sure nothing bad happens to them.

In order to protect your computer system from malicious activity, such as viruses, worms, Trojan, and spyware, you need a strong antivirus software.

While a few names have taken over this market (e.g. Norton, BitDefender, Avira, AVG), others may fly unnoticed, although just as valuable. Such an example is Quick Heal Antivirus.

In addition to blocking these already mentioned dangers, Quick Heal Antivirus also has a special technology called "DNAScan" that detects new and never-seen-before viruses.

The user interface is simple, and there's nothing that can be misunderstood here.

You have the option of scanning files and folders, emails, external drives and devices, all while maintaining an enabled firewall.

Scanning options include full system scan, custom scan, memory scan, and boot time scan.

In Custom Scan, you simply add the items you wish to be looked at, and Quick Heal will take care of the rest.

In addition, certain files and folder can be excluded, and of course there's also the option of scheduling a scan if you are forgetful or not around the computer.

Any suspicious threats will be send to quarantine or backed up.

Quick Heal Antivirus doesn't use too much CPU, and it's scanning time is the same as any other antivirus software's. We haven't found any errors to be worth mentioning.

You just have to use the trial for yourself, and if you are convinced, you can purchase this product for only $25.
