clamav VS arkime

My recommendation would be to use ClamAV an open source antivirus engine. It is a versatile tool designed to detect multiple types of threats from numerous file formats and other use cases (cross-platform, integration such as mail server). Finally, it is updated on a daily basis, ensuring protection against the latest known threats. This rapid update cycle is crucial for an antivirus tool to be effective.

Linux has (free) tools to improve security and detect/remove malware: Lynis,Chkrootkit,Rkhunter,ClamAV,Vuls,LMD,radare2,Yara,ntopng,maltrail,Snort,Suricata...

There's clamAV which is open source: https://www.clamav.net/

For personal use, the most commonly used is ClamAV.

Absolutely but if the OP feels they must then they should look into the free ClamAV.

I'd go with what Bman said but second to that ClamAV is a good free option.

Ehhh, there is antivirus software for Linux, like ClamAV. Also a lot of exploits these days target browsers since its an easier attack vector. Also, malware is malware, and most servers use Linux by default. So any malware that's targeting a Linux server could target a desktop user. I don't like the whole "Haha, malware doesn't affect me because everyone targets windows". Sure, those "download now!" buttons that are targeted to gullible windows users might not work on your operating system however your OS is still vulnerable and can still be exploited by malware.

Arkime: https://arkime.com/ Packet capture and search

Also consider running full PCAP collection with https://arkime.com/ so you can monitor your past network traffic. That has come in handy many times for security and troubleshooting, and doesn't require as much horsepower as you might think.

Anyone using Arkime? https://arkime.com/

dns && ip.src==x.y.z.w Note that this display filter will not display the DNS replies for the requests sent by x.y.z.w if you want those as well then it will be dns && ip.addr==x.y.z.w Although DNS will be displayed in upper case in Wireshark, it has to be in lower case in the display filter, that said, like others said based on your exact needs and the size of your resulting pcap / pcapng file you may want to look at capture filters, finally if you are dealing with multiple gegabytes file(s) you may want to take a look at another tool like Arkime (formerly moloch) https://arkime.com/

Full PCAP's? Look at https://arkime.com/ or network miner. Arkime is probably more what you're looking for. But I love network miner

I used moloch which is now https://arkime.com/. It used to be free and was a great tool for pcaps. Uses elastic underneath.

Arkime is secure, scaleable, indexed packet capture and search tool that can improve your network security by providing greater visibility. This open-source tool stores and indexes network traffic in standard PCAP format. Our thanks for the suggestion goes to Security_Chief_Odo.

I would suggest instead of graylog look into something like this https://arkime.com/
