The lightest paid antivirus program we tested is Bitdefender Total Security, which slowed our test laptop between 7.7 and 17 percent during active scans.

Bitdefender is also one of our picks for best antivirus overall.

Which Antivirus Use The Least System Resources? Free Antivirus Program

The lightest free antivirus program was AVG Free Antivirus, whose system impact ranged from 5 to 11 percent.

We used our home-grown OpenOffice benchmark test, which measures how long it takes the CPU to match 20,000 names with 20,000 addresses on a spreadsheet.

We measured system speed before any third-party antivirus program was installed; after an antivirus program was installed, but not during any active scans; during a full scan; and during a quick scan.

Each test was run three times for each program, and the results averaged.

The numbers recorded were the completion times of the name-and-address matching tasks.

Slowdowns were calculated using the pre-installation completion times as baselines and calculating the percentages by which each task increased the amount of time needed to complete the matching task.

Baselines were taken separately for each programs set of tests.

The results Neither Bitdefender nor AVG were the fastest in all three categories that we measured: passive system impact, full-scan system impact and quick-scan system impact.

But both were in either first or second place for all three, while most other programs were less consistent in their rankings.

For example, Trend Micro Maximum Security beat Bitdefender, 3.4 percent to 8 percent, for smallest passive system impact, measured while the antivirus software was running but not actively scanning.

However,Trend Micros full scan hit our test laptop like a ton of bricks, slowing it down by 68 percent.

Youd probably notice that slowdown even if you were just checking email.

Likewise, Panda Free Antivirus (7.4 percent) had less of a quick-scan slowdown than AVG (10.3 percent).

But Pandas full-scan slowdown was in the middle at 23 percent, while AVGs was less than half that at 11 percent.

There was a runner-up among paid antivirus programs.

Kaspersky Total Security came in third place in all three test categories, even as Bitdefender fought other programs for first.

There were a couple of free programs that did well, but for which we couldnt run all the tests.

Microsoft Windows Defender had the second smallest full-scan impact, and the third smallest quick-scan impact.

But its built into Windows 10 and automatically runs if no third-party antivirus program is present, so we couldnt really measure its background impact.

We can safely assume it is less than most other programs impact, though.

Bitdefender Antivirus Free Edition was second for both passive impact and full-scan impact, but it doesnt have a quick scan.

Most antivirus brands offer three or four different paid Windows programs, all sharing the same basic protections but adding a few more extra features with each increase in price.
