I'm using portable apps, from portableapps.com. I don't really like the selection of anti-viruses.
Is there a free portable anti-virus I can put on my thumb-drive? I would be using this to fix people's computers that have viruses on them. I don't do it as a business, I just do it to help people out at work (you know how that goes haha) hence why I just want a free AV that's portable.
