Hi, I'm using the above mentioned antivirus because my university provides it for free. However, I'm having doubts on whether it actually works or not. Just earlier today I inserted my thumb drive into my friend's PC which had kaspersky installed, and I was shocked when right away a message came up on top of the taskbar saying that my thumb drive was infected by a solow virus. Just before that I put the thumb drive into my laptop and mcafee didn't say anything. I'm pretty sure that drive was infected from a long ago incident and hence would be infected when I put it into my laptop. After meddling with the settings abit, I concluded that you can't even make virusscan scan thumb drives automatically when they are plugged in, which I think is horrible. Furthermore, in all the time I've been using it the virusscan hasn't detected a single virus/spyware even though I have the spyware module installed. So I guess my question is, does anyone else here use this virusscan or similar versions and what do you think about it? And, I'm considering switching to Avast which I hear is the best free antivirus. Does Avast at least scan thumbdrives automatically? Thanks for your help.
