Yes, it does gather data from your usage history. But after installing the program, you can opt out of data collection under the privacy settings. Software security experts recommend cleaning up and defragmenting your hard disk and uninstalling any unnecessary software before installing an antivirus program.
Be patient and allow the antivirus software to do its job, even if it does create lag in normal computer operations. We created our AVG AntiVirus review by studying its software, reading others' reviews of the program, and downloading and trying the program for ourselves. Please read our methodology to learn more about how we review products.

One of the oldest antivirus companies, Avast has been protecting people since and is trusted by more than million users around the globe. Essential protection: Avast Free Antivirus consistently ranks extremely high for its core virus protection engine and malware removal tools. Avast continues to support Windows 7, even though Microsoft has stopped updating that operating system. Features: Offering an easy-to-use interface, a secure web browser, a network security scanner, and more, Avast has a wide range of useful bonus features.
Lifewire praises its Do Not Disturb Mode, which blocks pop-ups while you watch movies or play games. Need a second opinion? One of the pioneers of free antivirus software for Windows, AVG has consistently won awards from AV-Comparatives over the past decade — including Top-Rated Product in their most recent test.
It's unlikely anything is getting through this. Avira has been creating antivirus applications for a long time, with the first one dating back to Bitdefender protects millions devices around the world and is consistently recognized by independent test labs like The Independent IT-Security Institute.
Russian cybersecurity firm Kaspersky has faced allegations of inappropriate connections to the Kremlin , prompting the US , the UK , and the Netherlands to ban the use of Kaspersky products across government agencies. Nevertheless, the allegations remain inconclusive, and Kaspersky is consistently a top-rated antivirus product. If this app is already on your PC, you might be wondering why you should even bother with a free third-party antivirus solution.
Its malware detection capabilities have improved, and it performed well in hands-on testing. Still, PCMag gives it a rather lukewarm review:. Many free third-party apps are more effective at keeping you safe. The company will continue to support the antivirus software for the time being, but their overall support for Windows 7 has ended, and they recommend you upgrade to Windows Essential protection: PCMag reports that Sophos achieved excellent scores in their hands-on tests and excellent protection against malicious websites.
But unlike the other major players on this list, Sophos has few independent lab test results to prove its efficacy. Sophos also received a poor phishing protection score from PCMag.
It's extremely short on features, though, and we'd like to see more coverage from the testing labs, too. So here are few more antivirus products to consider:. Essential protection: Adaware Antivirus Free has received mixed scores in past independent tests, and PCMag cautions that Adaware has no recent test scores to show.
And for an antivirus, protection should always be the 1 concern. Check Point ZoneAlarm is a free antivirus-firewall combo that licenses its antivirus engine from security giant Kaspersky. Essential protection: Pairing strong antivirus prevention with a firewall can be good enough for basic computing. Features: Unfortunately, this free cybersecurity solution is missing many features you would expect to see, such as web-based security, protection against malicious websites, and personal data protection.
Essential protection: Qihoo formerly used the same core antivirus as Bitdefender and Avira, but it no longer does. Sadly, its malware protection has suffered for it. Features: Qihoo comes with an impressive suite of bonus features, including cleanup and tuneup utilities, an adblocker , and more. Yet that's about it. To check AVG AntiVirus Free's impact on system performance, we used our custom benchmark test, which measures how long a CPU takes to match 20, names and addresses in an Excel spreadsheet.
Before we installed AntiVirus Free, the computer finished the benchmark task in That completion time rose to 14 seconds after AVG was installed but before a scan was run. That equals a passive performance loss of 5.
This makes AVG one of the slowest scanners among free antivirus products. Worse yet, that scan time doesn't decrease as the program gets to know your system over time. CPU performance slowed by 7. That's the second-smallest full-scan impact of all five free programs we examined, after Kaspersky Security Cloud Free's 5.
AVG's Computer Scan is similar to a quick scan. It took 1 minute and 36 seconds to finish, making it one of the fastest in the free-antivirus group. It took our benchmark test That's a lot more than Kaspersky Security Cloud Free's 1. AVG AntiVirus Free's interface is dark with bright-green elements that stand out well from the black background. When everything's OK, there's a white check mark at the top of the main interface window. Also prominent is a Scan Computer button that you can customize and schedule.
Performance Scan checks for junk files and potential problems, but you need to pay for and install a separate program, AVG TuneUp, to actually fix anything. The grayed-out Hacker Attacks and Privacy and Payments features are for paying customers only. The Help section links directly to tech support. The Settings section offers an excellent assortment of customization options, including a scan-sensitivity slider and toggle switches for the Behavior Shield, File Shield, Web Shield and Email Shield.
The Do Not Disturb mode reduces interruptions during gameplay or movie watching, and the System Tray icon can turn protection on or off and start a scan. The whole process took us a little more than 7 minutes. Be sure to uncheck the box that installs the Google Toolbar in your default browser.
