I've been using the proprietry ESET antivirus for Linux, since 2014, on almost all setups (see signature). I also use the ESET for Windows version on my dualboot setup.
How useful is it? That's a good question...
What I find it
is good for, is promptly alerting me about risky websites while surfing the net, including potentially unsafe downloads - it seems to do it's job there. Apparently, all AV software wont detect malware that comes associated with apps, which I think is the majority of malware on a PC.
Why did I start using ESET? Earlier, back in 2014/15, I experienced a malware attack on LL (which I reported on the LL forum) in a dualboot setup with Win8.1. Since then I use ESET for both Linux & Windows OS. Also, I'd imagine if most servers worldwide are based on Unix, and therefore are potential targets for malware or hacking, then it follows that Linux (descended from Unix) might be vulnerable to..? However, some argue that buying AVs is a waste of money and is merely a tickbox exercise and
rokytnji in the previous post seems to express a similar view.
Since installing ESET, it hasn't detected any malware on any of our setups (including Windows OS) - there are two opposing interpretations for that..
(1) malware is getting through and the AV is just not detecting it
(2) no malware getting through, hence no detection
However, there are just one or two comments I'd like to add, quoting '
quidsup'. Quidsup (a.k.a. Ian) has a linux channel on YouTube. His opinions are respected by a wide audience - his professional daytime job is as a network security analyst so he is well placed to express a viewpoint on security in either Linux or Windows OS.
His opinion is that AVs are only around 20% efficient, at best, as most malware comes with apps, e.g. adobe flashplayer, java, etc., and this app-associated malware is undetectable by AVs. In one of his videos he said that Linux presents a brick wall to viruses, and so there was no point having an AV to guard a brick wall - a waste of time in his opinion.
Virustotal and
urlquery are useful malware detectors (they are free), which were recommended in one of Quidsup's videos - it's amazing what
urlquery might pick up, even on seemingly 'safe sites' - a scan of my son's school website picked up malware... You can find these scanners at the following links :
