RIP to my friend's (Jan) laptop.

So my friend's laptop finally rest in peace after weeks of battling with a virus. Apparently, she's not the only one experiencing that.

The virus came from Joli's (an art supply store nearby our college building and the only one that offers various printing services). It affected a lot of USBs (including mine) and to the point that some files became corrupted and became nuisance for my classmates who were supposed to be submitting files in various subjects. When I noticed that my USB is acting strange, I decided not to use it anymore until I get a decent anti-virus. Good thing that email, Dropbox and Facebook are there to store my files for me. It's a hassle to log in but at least I'm sure that my files are safe.

I also tried searching for alternative printing shops as well. There are some that's much cheaper but I know there will be times that I'll end up in Joli's. I'm saving up to buy an extra USB that will be a temporary one (a USB that I can format immediately every time I print again and again).

Do you guys know a good anti-virus that works well and for free? I don't want a noisy one like Avast for the love of Christ.
