Yes, sandbox and backup and, most importantly, be careful on the internet - don't click the sexy lady,man or other, banners. I couldn't be bothered looking before that but reckon that the result can be extrapolated. Not once has anyone on this forum have a bona fide virus/malware/rootkit/ransomware in the last 5 years.
#FREEFILESYNC MALWARE VIRUS PROFESSIONAL#
It is more used in a professional environment than by SOHO users and requires a complete configuration. SELinux is a Mandatory Access Control (MAC) system which is a kernel (LSM) enhancement to confine programs to a limited set of resources.
#FREEFILESYNC MALWARE VIRUS INSTALL#
Much more efficient protection exists: in Ubuntu and Mint SELinux is not activated (while it is in Fedora, Redhat.) it is even not maintained in Ubuntu (user who woud want to install it should install Debian one). It is easy to do, websites such as osboxes even offer to download pre-built Virtual Box or VMware images of tens of free operating systems.
Still increased protection would be to virtualize internet access, and build in a virtual machine (VirtualBox, VMware Player) a guest operating system dedicated to internet use: in case of any problem, this virtual machine would be compromized, not the host (main one). Since downloaded files and e-mail attachments are generally found in Downloads directory, an access scan of this directory is feasible and may increase security.Īs I mentioned it, sandboxing internet apps is useful to increase the difficulty to exploit a vunerability. Moreover, Clamav log is plenty of errors unless you remove from scan most of system sensitive directories. Note that Clamav is slow, even when running its daemon version, and to use it to protect the whole system (to scan each file read or written) would probably prevent normal system use. Other OpenSource tools (rkhunter, chkrootkit and Linux Malware Detect) are on-demand scanners only, and will not prevent anything.
Now, SOHO users offer is very limited: free and OpenSource Clamav or pay Dr Web (NB: I don't know how clamav compares to Dr Web).
If updated (and if the ransomware does not use undisclosed "zero day" vulnerability), antivirus program will try to prevent opening the corrupted files, for ransomware and other kinds of malware. Program running is the background is an antivirus program with on access scanning. With a question about YOU are the ones who do the encryption? Speaking of ransomware like wannacry and others that encrypt your files:Ĭan't there be any program in the background which is monitoringĪnd put a stop for this BEFORE it happens?
