Well, it's nice you gave me examples from the real life. However, I thought you were using CFP 3.0 for HIPS protection!? What do you use for protection? Do you recommend me to have CFP 3.0 with HIPS or Online Armor (shareware)? Because my USB memory stick is frequently infected with malwares (especially when I'm writing my diploma)-so far I was lucky, I've been able to catch them all, but for how long? Also, to catch malware with CFP 3.0 should it be in Custom Policy mode, Paranoid mode, Very High frequency alert level? Thanks for the informations and advices you casn give me!
