Below are five of the best professional antivirus programs that will do well protecting your computer from viruses.
My favorite is for sure Malwarebytes Premium, but these are in no particular order:
Malwarebytes is the most often used on-demand virus scanner on the market - even the free version. However, this premium edition gives you real-time virus protection, scheduled scanning, and everything you'd expect in an antivirus program.
There are three scanning modes to scan custom areas of the computer, the entire system, or things like the memory to find currently running malware.
Main Features: Real-time protection, blocks phishing attempts, scheduled scans, heuristic scanning, update scheduler, compatible with other antivirus software, finds rootkits
Compatible OS: Windows 10, 8, 7, Vista, XP
Malwarebytes is one of the cheapest antivirus programs I could find and it even works on 3 computers.
There's a 14 day trial available so you can test Malwarebytes Premium without spending a dime.
Buy Malwarebytes Premium ($39.99 - 1 year, 1 PC)
If you pay for Malwarebytes Premium for two years instead, the price is $59.99 for those two years, which is essentially $30 /year instead of $40.
You can also buy this program for 2-10 computers for $10 extra for each computer (e.g., six computers would cost $89.99).
