HI I was wondering if I could ask a question. I was wondering if Avast 6 did encounter viruses, malware or trojans does avast have a feature in it to make sure that viruses, worms, trojans cannot disable it.
The reason I ask this question is because I just read an article about Apple’s os X xprotect can be disabled by malware.
So I was just curious if avast can be disabled by viruses, or worms or trojans or malware at any time.
hi diddy,avast does have a self defense feature,i dont think its enabled by default,just open user interface,open settings,select troubleshooting,and make sure enable avast self defense module is checked.
but i dont know if there are any malware,viruses etc. that could disable it even if self defense is enabled.
Well in my case, since I’ve had AvastI have not had any major problems with any malware yet, but:
As far as I know some mallware and trojans can disable your services, like your security center service, when your services stop working most of your alerts and basically your anti virus becomes useless…they can also change the anti virus to recognize them as a windows software and bypass them…I’ve even heard of people that couldn’t start their computer at all because of a trojan, or the computer shutting itself off…That is why it’s good to have an antivirus scanner on a USB device or a second opinion scanner…I have ClamWin portable scanner on my USB…It’s very slow at scanning, but pretty accurate and easy to figure out…
TC… and safe surfing
In these cases, Clam(Win)AV is mentioned just for a “portable last resort” option. For this purpose, it doesn’t need to be perfect for each and every situation (or malware). It just needs to help identifying the possible malware that prevents you from using your normal security tools under your normal OS.
ClamAv is not the “only” option (several security rescue CD/UFD systems are available), but it is a valid one for some cases.
Sorry to be hard, but for me, help means go further, have a better detection.
Otherwise, you have already the possible protection.
It’s an illusion, lose of time, imho.
To help, it needs to be better (in terms of detection).
Tech, it needs to cover the specific problem that the normal AV is not covering (since the case presented is that the normal AV is being disabled).
It doesn’t need to cover “more”, but it needs to cover the specific “other” case (when the normal AV is not available). So if it covers the 100% of the target cases, it is still usefull for those specific cases.
Once the info is achieved, the user could find out how to overcome the situation and get back the normal AV to work.
One tool can’t cover “all” situations, so use the most adequate tool for the targeted problem and for the specific user.
In the midst of a nasty experience (37 applications infected by 3 malwares, only 3 days ago), I praise Avast for its capacity to resist.
AVG 10 recognised the threats, but… 3 of its essential applications got infected and sent to vault in the process;
Spybot was obviously mistaken (Backdoor trojan in combination with “Win 32” viruses);
Malwarebyte collapsed;
the Iobit ASC malware search application got infected;
Avast is operational so soon after booting that it neutralised 2 major pests invading up to the various rescue and recovery points, as well as the update services applications (“Win32:Malware-gen”, alias “BackDoor.Generic14.AVBQ”).
It then prompted a request for a scan in DOS while rebooting, wich gave me a clear indication and the possibility of a partial purge, until that particular programme collapsed as well.
All I have to do is reinstall Avast again and again, to chase the beasts and understand their bad manners.
An excellent tool indeed, but it would indeed be so useful, if its DOS application could hold on an external booting device!
