Hi Steve,

Quick Heal provides IT internet security solutions to protect your PC, Mac, Mobile, Tablet, Server and others.
Installing an antivirus program and keeping it up-to-date can help defend your computer against viruses. Antivirus programs scan for viruses trying to get into your email, operating system, or files.

If you are not satisfied with Quick Heal, then here are some of the alternatives you can use instead of Quick Heal:

1.Bitdefender Internet Security
The Bitdefender suite comes with Bitdefender Antivirus Plus - also available separately which works great. Ransomware protection can be quite handy as any unknown program looking to lock down your personal files for money will be halted.
Bitdefender does offer a free version of its antivirus tool so if the 30-day Internet Security trial doesn't have you convinced, go for that.

2. Kaspersky Internet Security
Unlike others, the Kaspersky firewall doesn't bother users and intelligently knows which programs to allow or block. It also won't throw pop-ups onto your screen whenever a new application has a request, and will decide on a level of access after studying things such as digital signatures.
It not only blacklists known scam sites but it can try to figure out newer ones using its heuristic analysis component. The software will even offer to scan through your installed applications and look for potential vulnerabilities.

3. Symantec Norton Security
Provides real-time protection against existing and emerging viruses and malware.Delivers comprehensive protection you can’t get from free antivirus software or your computer’s operating system.

It backs up your photos, financial files and other important documents of your choice on your Windows PC.

But please keep in mind that an antivirus helps you in keeping your computer secure and not deals with the performance issues.

So, if you figure out that you have some performance issues, you can go the below link and explore various products from Reviversoft:

One such product is Security Reviver which will scan your PC and identify security threats and vulnerabilities. Security Reviver can quickly and safely remove these threats and prevent them from reoccurring.

I hope this helps in making a decision for using the best antivirus for your PC.
