Post by: lee16 on July 03, 2004, 11:52:00 AM
Am i right in saying that avast! home can't do a boot scan?, if i am, can someone tell me if there ever will be a boot scan for avast! home.  ???

Lee, the limitation is on Windows.
Boot time procedures are a NT process. So, like shgoh said, only in 2k/XP.
You can add a link in your startup folder. Try:

"C:\Program Files\Alwil Software\Avast\ashQuick.exe" "*MEMORY"
The *MEMORY parameter causes avast! to scan the operating memory of the computer: the true virtual memory.

"C:\Program Files\Alwil Software\Avast\ashQuick.exe" "*STRT-MEM-SHORT"
The *STRT-MEM-SHORT scans (besides the startup items) the modules loaded in memory: the corresponding files, not the real memory.

While the *MEMORY parameter may catch unknown (packed) variants of viruses that may not be detected on disk (they can be found since the packed file is already unpacked to memory), it may also fail to detect the viruses for which only a packed variant exists (and the VPS does not contain a signature for the unpacked code). Generally, avast! virus database is optimized (and checked) for the file detection - the memory scan is rather a special additional feature.

"C:\Program Files\Alwil Software\Avast\ashQuick.exe" "*STARTUP"
The *STARTUP parameter will scan all startup user accounts items.

"C:\Program Files\Alwil Software\Avast\ashQuick.exe" "*STARTUP-SHORT"
The *STARTUP parameter will scan the current user startup items.

So, if you want a real thorough check of the memory/ startup, I'd rather recommend using both the parameters *STRT-MEM-SHORT and *MEMORY together (or, *MEMORY, *MEMORY-SHORT and *STARTUP for all the user accounts).

Like this: "C:\Program Files\Alwil Software\Avast\ashQuick.exe" "*MEMORY" "*STRT-MEM-SHORT" "*STARTUP" "*STARTUP-SHORT"
