portable antivirus s/w, anyone?

due to an influx of viruses/trojans on school coms, every1 has been afraid to plug their thumbdrives in. their AV software don't seem to help in any way. i'm thinking if there's any portable AV that can be installed on the thumbdrive to scan strictly for any incoming viruses or not.

tried searching for eset portable but seems like it's a fake, cos' i couldn't find it on the originator's site. any idea?

u want to protect ur own pc/thumbdrive? or u want to scan/clean every host computer u plug ur thumbdrive into, using no-install av (which is impractical)?

i think they are 2 very different things.

How? If host pc is infected, u have to do complete scan/clean using dr web cureit on the host pc & ur thumbdrive - how long would that take, sit there & wait?

Then bring thumbdrive back to ur pc, u will undoubtedly scan the thumbdrive again. So why bother scanning/cleaning the host pc anyway?

nope i'm not going to protect the com, not the it admin anyway.

just gonna protect the thumbdrive from viruses, which means to scan any intrusion into the drive.

I thot so too, so i think dr web cureit, clamwin portable etc is NOT what u are looking for. Think u want those u3 type usb AV (e.g. avast!) that runs a realtime av guard for ur thumbdrive. I dun have any experience with those (i hate u3), but NONE ARE FREE i think. Also, if u pass ur thumbdrive to fren, doesn't mean ur fren will run or update the u3 antivirus for u.

Bottomline is, probably easier to protect own pc than to protect thumbdrive. Eg. disable autorun, always manually scan thumbdrive after it has been in other pple's pc, look to see if any unknown files added inside thumbdrive etc. Important files in ur thumbdrive backup to own pc 1st before lending out or using outside.

Some pple also suggest creating an empty Read-Only file "autorun.inf" on an NTFS-formatted thumbdrive (edit, also need to deny all for all users in permissions). Will not prevent malware files being copied to it, but prevents bad autorun.inf file being created that will autorun the malware on another fren's pc.

eh.. i thought the thumb can only be formatted in fat32 mode? the autorun dummy's a gd idea. i had one virus previously that cloned all over my com and also other PCs with autorun.inf and another file in recycler, very irritating.

yup something like u3, but i don't like it too any non-u3 and realtime thumb scanner would be appreciated, don't mind paid s/w.

Ntfs also can, just google. BUt some say increase wear.

Non-u3, with realtime guard - dun think there is. Easier to disable autorun & just scan with ur own PC's antivirus after use. Personally i prefer to use a virtualized/sandboxing app (e.g. Returnil) before plugging any suspect thumbdrive in my com. Or dual-boot to linux OS if u already using.

hmm, ntfs or fat32 will make a diff in malware intrusion? what's the relationship here?

u see, when the sch com is used to do some work, then after that transfer work to thumbdrive, so only can be scanned with the sch AV(which is damn lousy, low hit rate) . if plug into own laptop and scan, it'd be too late already. malware can make intrusion from the moment it's plugged in, even when it's in not autorun mode. don't know how it works though..

tried sandbox last time but feel it's too troublesome already =/

It's only to set the "read-only/deny all" file permissions for the dummy autorun.inf file.

If plug into own laptop and scan, it'd be too late already. malware can make intrusion from the moment it's plugged in, even when it's in not autorun mode. don't know how it works though../
No lah, malware file = program file = must be executed for it to run & infect. No autorun means it remains a file in thumbdrive that's not run.

When accessg the drive via My Computer, safer to Right-click> Open, instead of double-click. Some systems will still autorun when d-clicking on drive, despite autorun disabled. Not sure why, but happens on some PCs.

Sorry, what I said above is wrong. Shud be:

Safer to use My Computer> Folders> From left pane, access the thumbdrive.

Because some systems will still autorun when D-clicking on drive, or Right Click>Open despite autorun disabled.
