Antivirus is a kind of software used to prevent, scan, detect and delete viruses from a computer. Once installed, most antivirus software runs automatically in the background to provide real-time protection against virus attacks.
Comprehensive virus protection programs help protect your files and hardware from malware such as worms, Trojan horses and spyware, and may also offer additional protection such as customizable firewalls and website blocking.
Most provide real-time protection, which can protect your devices from incoming threats; scan your entire computer regularly for known threats and provide automatic updates; and identify, block and delete malicious codes and software.
Antivirus software begins operating by checking your computer programs and files against a database of known types of malware. Since new viruses are constantly created and distributed by hackers, it will also scan computers for the possibility of new or unknown types of malware threats.
Typically, most programs will use three different detection devices: specific detection, which identifies known malware; generic detection, which looks for known parts or types of malware or patterns that are related by a common codebase; and heuristic detection, which scans for unknown viruses by identifying known suspicious file structures. When the program finds a file that contains a virus, it will usually quarantine it and/or mark it for deletion, making it inaccessible and removing the risk to your device.
I would like to know the location, I am experimenting with Regular Update and Pre-release update, and I notice it replaces the whole 48,000+ KB virus signature database file whatever, my question is does switching generates dump/dmp files or temporary/tmp files?
Pre release updating is usually for updating issues or fixes within some of the modules. Some corporate businesses will have a break and need the update by yesterday and ESET can push out the fixes quickly without releasing to general pop and also test before release. I dont think you will find vsd in prerelease but i could be wrong.
You can use pre-release if you like, no it won't affect your internet speed or increase the resource usage in anyway. By using pre-release updates you will get module updates faster hence "pre-release" but that's about it.
Yes ESET doesn't push out VSD updates every hour like some other vendors since it's not really needed, between the traditional VSD updates you get updates from the cloud more or less in real-time to the product wich will cover you just fine.
I've been taught that I should never install two antivirus (AV) softwares together, because they will conflict. Even Windows Defender (since Windows 8) disables itself upon detecting another AV software.
I'm curious how two can conflict. The only scenario I can currently figure out is when both detect the same virus and try to quarantine it simultaneously, which can result in a "virus conquest battle". To me this surely isn't a convincing reason not to install two AV softwares.
AV software with live protection features deeply integrates itself into operating system. It patches some of OS code so that it can observe whatever programs attempt to do and prevent them from doing so, if necessary. Operating systems don't provide such capabilities out-of-the-box, so AVs use less conventional methods to achieve this effect.
For example, it can replace the "write file" function that OS provides with its custom one. When a program attempts to write to a file, it will call the "write file" function. But the function was patched by AV and program's request will be redirected to AV instead. AV will inspect it and decide if it looks OK. If it does, it will call actual "write file" function. Otherwise, it will take appropriate action to prevent malicious software from doing any damage.
Unfortunately, patching of OS code is not only necessary for AVs, but also suspicious. If you were creating a virus, wouldn't you also like to be able to intercept system operations, for example to prevent AV from scanning virus files?
In some cases, even AV scanners without live protection can interfere. How do AVs detect viruses? Well, they have their virus signatures, ie. databases of distinctive features of known viruses. And so it happens that such database can also appear suspicious, because, well, they have distinctive features of viruses. So one AV could hypothetically detect other AV's signatures as malicious code.
There are also AV engines designed to coexist with other AVs, for example Hitman Pro. ClamWin (which is free and open-source) should also be relatively issue-free when coexisting because it contains only a scanner without any live protection.
Programs conflict when they both attempt to use the same resource. When multiple programs attempt to operate on a resource at the same time, there is a risk of Concurrency Problems. Concurrency problems occur when one process performs a change on the resource, and the other program (which was in the middle its own modification to the resource) is unaware of it, and thus unable to accommodate.
A married couple have a shared bank account and ATM cards. They have 1000USD in their account. In their daily life, they are on opposite sides of town, and both access the ATM at the same instant. They both withdraw 1000USD. The ATMs both know that the balance is 1000, so they allow the withdrawl, and then write back to the central database that the new balance is 0.
There are a few ways to deal with these kinds of issues. One is to use software that arbitrates between the multiple parties accessing the resource. These arbiter programs have two options, depending on the scope and predictability of the operations:
This means that both programs are racing to access the file, and whoever gets there first gets the lock. At a low level, this results in some disk thrashing as both programs begin their own I/O activities, forcing the hardware to do both tasks separately, yet interleaving the IO instructions, making both much less efficient, and in the end, only one of them will win. the other will spin and wait to be able to establish their own lock.
Hello,
I own a MyCloud EX2 Ultra upgraded to FW 5.13.115
I can not use Anti-Virus Essentials v. 1.30: just asking for database update takes hours
and the scan is never ending
I also tried to refresh database using SSH command line freshclam with verbose and debug mode enabled
After a while i see db being dowloaded but then it gets stuck on
LibClamAV debug: daily.cvd loaded
Hi, I add some update issue.
I lunched update of DB only yesterday and it took some (3 to 4) hours but it worked
Then I started an antivirus check of a shared folder (151gb) and now it is running since 24+ hrs with 0% progress.
The nas is running something since disk are noisly spinning and cpu is 75%
I understand it can take time, but do not understand 0% progress so far
Hi, I installed the App upgrade.
The 0% issue has been solved BUT the database update is still taking a LOOONG time
It gets stuck at 82% and then completes in 8 hours
It is not usable at these conditions
Regards
L.
I have the same issue with v1.35 and latest bios on my ultra ex 2: download new virus definition always stops at 99% and never stops while hard disks are running the whole time. stop only if I delete whole anti virus app
We have successfully used LogMeIn Antivirus for a year on many Windows 10 Pro computers; however, I just installed it on several new Windows 11 Pro computers. The program appears to install and the policies seem to apply correctly; however LMI Central is not getting updated information from the computers.
I have changed the LMI AV policy to turn off the firewall and have also disabled the Windows firewall as requested by LMI support. I enabled logging in LMI Control Panel and uninstalled, rebooted, and reinstalled LMI AV and sent the debugging logs to LMI support.
Hi @remoteworker93 I see you have a case with support. Our team is currently reviewing and should have an update for you shortly. Thanks for sharing this experience and I hope to have a resolution for you soon.
Same issue for us. Logmein says we do not have real time anti virus. The desktops show they are. We have turned off and turned on the real time. Still same issue - shows not real time. Annoyance. Not a problem though.
LMI Support did eventually fix this issue which was on their end. This was their response: "I would like to inform you that an update was made and the issue with the AntiVirus was corrected, could your restart the computer and let me know if is working fine."
Disseminated via infected floppy disks, the virus itself was harmless, but it spread to all disks attached to a system. It spread so quickly that most cybersecurity experts consider it the first large-scale computer virus outbreak in history. Another early problem was the Morris worm back in 1988, but that was a computer worm rather than a computer virus.
