These Are The 5 Worst Antivirus Software Of 2024 That Make Your Computer Slow, And These Are 5 Fast Software

These Are The 5 Worst Antivirus Software Of 2024 That Make Your Computer Slow, And These Are 5 Fast Software

Last week we talked to you about the safest antivirus software that we can install on our computer right now . This helps us to have the best level of security and protection from all types of computer threats. However, not everything is about security. If we want our computer to work properly, in addition to being well protected, it is essential that the antivirus does not make our computer run slowly. Therefore, today we will explain to you what are the fastest and slowest antivirus software for 2024.

These security programs are characterized by continuous analysis of the system and all the activities that take place in it. For example, the antivirus program is responsible for scanning all the files that are copied, when we compress and decompress files, when we install or run programs, download files from the Internet, and even browse the web.

Each of the tasks we have just seen consumes the resources in the system. And these resources can eventually negatively affect the computer. Therefore, depending on the type of computer we have (new, old, high-end, medium, low-end, etc.), it is very important to know how to correctly choose the least suitable antivirus for it.

So, today we will see which antivirus software is the fastest, and which one makes your computer slower.

- Fastest antivirus software

For the tests, AV-Comparatives used an Intel Core i7 PC with 8GB of RAM and an SSD, running Windows 10 64-bit. Nothing out of this world. After setting up each PC and each antivirus, performance was measured using various tools to see how much each security program affected performance.

So, for example, we found that the fastest antivirus we can install right now is McAfee. This security software, owned by Intel, has the least impact on the computer. If you look at the AV-Comparatives breakdown, it gets a perfect score in all tests, except for launching applications for the first time, where its score drops to 2 out of 3. Subsequent launches of programs do not affect the performance of the device.

Secondly, we find ESET. This security software is very veteran in the industry, and it has also managed to show impressive performance. In this case, it does not slow down the computer when you first launch the programs, but the overall performance of the computer is slightly lower than that of McAfee.

We give the third and fourth places to Avast and AVG respectively. In this case, the results are the same as those we can find for ESET, that is, it does not slow down the computer at any point, although it is true that the overall performance of the computer is lower than ESET.

And the fifth place we give to Norton. This program again repeats the results of the previous programs, getting 3 out of 3 in all tests, but with an overall system performance somewhat lower than that of previous security programs.

Kaspersky is another antivirus that promises good performance. However, considering the problems the company has, we prefer not to consider it.

- Slowest Antivirus Software of 2024

After knowing which antivirus programs run the fastest and smoothest on your computer, we will also see which ones are the slowest. At this point, we find ourselves with the worst of all, Total Defense. This security software makes even high-end computers run like an old, low-end computer. It slows down your computer when copying files, compressing and decompressing them, installing programs... a burden that should be avoided.

In second place is F-Secure. The performance issues of this antivirus are similar to the previous one, plus it also slows down the computer when we run any program on the computer. Third place goes to Bitdefender, another security program, although it doesn’t get very bad results overall, the performance when running programs, whether for the first time or consecutive times, the CPU becomes a bottleneck.

Surprisingly, Microsoft Defender is in fourth place from the bottom. The security software that comes installed by default on Windows 10 and Windows 11 also makes your computer run slowly. This has been one of its problems since the beginning, and it continues to bear this burden to this day. Its biggest problem is when compressing and decompressing files, although we can also encounter problems when installing programs.

Finally, we find G-Data, another well-known antivirus that shows problems, especially when compressing and decompressing all types of files.
