Non-resident offline antivirus

Is there such a thing these days where i download definitions to install manually into completely standalone non-resident av software ?

Need to have a way to scan things on offline machines without installing crapware on them...

Aidstest for year 2014 anyone ? (older people will understand)

Do those machines need to be online during the scan?

Thats the point - they cant. And theyre crap so no resident software.

Windows Defender Offline may be something you could consider using.

Sorry, online as in booted to their usual OS e.g. A server. There are quite a few offline scanners that you can boot from a USB or CD - Windows Defender, Kaspersky, Avira all have bootable utilities.

Ok, so, i get a file/s that i need checked before i use it/them. Computer is not connected to any lan or wan, AV must be standalone, as in no installation required, non-resident to not grind down already bad pc performance. Something i can take with me on a usb stick, dont care about bootable, just executable under windows or dos'ish CLI.

Several AV companies provide standalone / offline definition updates. Qihoo 360 does, Comodo does, and Avira did last time I checked. We have just such a machine at our office and I just download Qihoo 360's daily update and put it into the right folder when I visit. It's set to protect local files, USB drives/attachable storage and so on and I update the signatures once or twice a week.

As the machine isn't online there's not much by way of high risk threat, but various people having access to the machine and needing to use USB does (and has) present trojan and worm risks, which Qihoo 360 has been perfect at preventing.

EDIT: Sorry just seen the last post about it needing to be portable/non-installed. You can get portable versions of Comodo, MalwareBytes, Hitman Pro (paid), and various others. Google will be your best bet.

Can we have a sticky that just says 'Hirens Boot CD'

Pretty sure that can be put on a usb and then you can run the utils on a net connected PC before hand to get it to incorporate the latest defs onto the usb.

Then when you run on the non net connect PC they all tend to extract to a temp area, run and then clean up once done, or just delete the temp files/folder.
