Some of malware that’s called Virus can inject itself into executable file.
Such as Win32.Virut , Win32.Alman , Win32.Fujack , Win32.Hala , Win32.Sality or Win32.Parite
It’s infect an exe files by modification an original file.
Back to a thread topic, I’m suggest Can the infected files repair by Comodo Antivirus ?
Because some AntiVirus software can’t do that it’s clean by deleting file.
No, They can only quarantine or remove, so far!
I believe that cleaning would come later in the dev.
Did this help you?
Yes a little.
It’s my little wishlist.
Hi boys 
The reason AV’s ( any AV in such case ) can not disinfect ( part of ) Virut infections is because Virut is verry buggy and may misinfect executable files so they end up corrupted :-\
Here an excellent article about it from Security Specialist Mieke Verburgh :
Greetz, Red.
so will comodo detect virut before it struck???
Defense+ will prevent the running from Virut before it can do any harm and infect your computer. (only if you recognise the pop-up of course)
Xan
so what setting should i use? paranoid ones??? ;D i have strucked once n i told you…it was disasterous!!! ;D i have to let go all of my *.exe…otherwise it wil infect again and again…
it depends i guess. if you install CIS on a new machine (therefore the machine is 100% clean/uninfected) then Clean PC mode or safe mode should be sufficient 88)
