I just switched from K7 Total Security (k7TS) to Panda Essentials. Reasons: 1- K7TS has a built-in Firewall (FW) component. Its FW is is only so-so and has a somewhat complicated rule-making/editing process. I would like to put in a better FW BUT K7TS's FW cannot be disabled. I asked K7TS's support for a fix or work-around. They quickly responded with a courteous pronouncement that their FW can't be disabled so -- live with it. 2- Thus, I decided to dump K7TS so as to get better FW protection. That meant I needed to find either: (A) 2 apps: a good stand-alone FW AND a good stand-alone antivirus, OR (B) 1 app: a good antivirus with a good FW built into it. 3- On another security forum I read some comments by a skilled FW sly guy. His posts indicated that Panda Essentials (PE) has an excellent, highly configurable FW. So I purchased a 1-month subscription to PE. (Yes, the Panda website offers MONTHLY subscriptions as well as annual subscriptions.) 4- Bingo! I found that PE's FW is grrreat!! Very configurable. No discernible impact on computer's speed & responsiveness. Extremely user-friendly process for folks who want to develop spacial FW rules. Minimal pop-up alerts PLUS those alerts give users the info needed to easily make sound decisions. 5- Bottom line: I bought a 1-year subscription to PE for $19.99 at Newegg. Installed it. Set it up. It's running as I write this -- smooth as a baby's cheeks. 6- BTW, I am running WiseVector (WV) alongside of PE. WV is an antivirus. It is nicely designed to run alongside other antivirus apps, if user desires. There is no conflict. WV is also VERY light so the PE/WV combo keeps my aging laptop very agile & speedy. 7- Reasons why I run WV together with PE: (A) @cruelsister thinks highly of WV & many folks (me included) think VERY highly of her security expertise. (B) WV has a built-in (but optional) process called "WMI FW" -- WMI stands for Windows Management Instrumentation (WMI). WV's WMI FW is a useful FW adjunct for reasons given in THIS article. (C) WV has a VERY unintrusive HIPS (Host-based Intrusion Prevention System). PE does not -- nor do most other top tier antiviruses. (D) WV has very advanced machine learning/AI to augment PE's capabilities for dealing with malware for which signatures don't yet exist. 8- Analogy: At night, I secure all my doors & windows. Even so, I also activate the burglar alarm. By the same token, PE secures my computer's doors & windows. WV is the burglar alarm. PE/WV is light so........ why not?
