![]() It did a very Fast "quick scan" and found nothing. Sophos is supposed to be less obnoxious than Avast but it apparently uses tons of CPU unless you have something like App Tamer ( ) to keep it under control.ĬlamXav is among a group of 'occasionally' tested apps which test in the 60%-90% detection rate.įYI yesterday I downloaded Avira. Avast too, but I've read elsewhere that if it convinces you to install WebShield it downloads VPN software it then tries to charge you to use, and that it loads several startup files and has lots of background processes running. (Free apps listed are Sophos, Avast, BitDefender and Avira.) All of these are rated as having an overall 90% or higher detectionįrom this test, Avira looks like a good free option. Other highly-rated apps are from Avast, ESET, Sophos, F-Secure, Kaspersky, G Data, Dr. Right now the very best results of regularly tested apps come from VirusBarrier (which I believe is the same thing as the $40/year "Internet Security X8"). Someone on macupdate recommended securityspread's ratings of Mac AV (free and commercial) whose results ( ) are updated every three months ( ) so you can compare AV products over time. ![]() They liked it, said it caught 94% of selected samples, but only 53% of pre-installed malware (which they nevertheless called "one of the better solutions"): Only 51 percent of the antivirus scanners detected the malware samples found in the past year on the first day of the study.Ī year ago Macworld UK reviewed ESET. The malware that Lastline Labs dubbed "least likely to be detected" indeed went undetected by the majority of antivirus scanners for months, or was never detected at all. After two months, one third of the antivirus scanners still failed to detect many of the malware samples. According to the study's results ( ), most of the newly detected malware went undetected by nearly half of the antivirus vendors. This means that if you click a malicious link or open an attachment in one of these emails, there is less than a one-in-five chance your antivirus software will detect it as bad." Last year Lastline Labs surveyed 47 vendors' AV programs against a variety of malware. ![]() The average detection rate for these samples was 24.47 percent, while the median detection rate was just 19 percent. In 2012 the security researcher Brian Krebs found that what is " noticeable is the lack of antivirus detection on most of these password stealing and remote control Trojans. There is a question about the general effectiveness of AV software in general, especially in the Windows world. (For example, as I noted above, that survey found that Clamxav caught 136 out of 188 pieces of malware, falling in the middle of the pack tested, but three months later its updated definitions would have resulted in its catching 100%.) The survey done a year ago by TheSafeMac ( ) might be of interest, but things move fast in the AV world, so the results are probably out of date. The last time I downloaded something which was designated as Mac malware was probably when I was running OS8, although I have had colleagues who have inadvertently sent me attachments that contained Windows malware. ![]() ClamXav has found Windows malware embedded in files that I've downloaded, and therefore been able to make sure I do not pass along to Windows users. * ClamXav only catches ~72% of malware, but author states it was because of issues picking up new signatures which supposedly is fixed now according to the ClamXav forums.Įither way, I'm just trying to prevent myself from forwarding emails/attachments with malware to Windows users. * ClamXav catches ~39% of malware, according to them. ![]() I just hope the few reviews out there saying ClamXav doesn't catch most malware aren't 100% true. Sophos is nice, but on my older non-retina MBP it felt sluggish even with a Intel SSD/8GB RAM. I thought about VirusBarrier, but to pay $40/year just to monitor my email/downloads folder is too much especially with my strict, safe, computing practices. That said, since this is my main home computer, I don't really need major AV software. $23 is a not a bad deal especially when you factor in 6-7 years of free usage on my part. You can only scan folders via scheduling or manually, which pushed me to buy the commercial copy. I tried the App Store version, which runs on Yosemite despite being last updated Aug 2014, but it's missing the Sentry real-time monitoring feature (Apple/MAS limitation?). I just pulled the trigger on the paid version of ClamXav. ![]()
