This may seem like a daft question but is it possible for a PC that is not switched on to be infected with a virus. The reason i ask is that someone in work has just come back from a vacation in Florida and on his return, turned on his pc to find a message from AVG saying a virus was detected, according to the software the virus was downloaded on the 10th but this was a week into his holiday. The computer is connected via BB but obviously there was no power running to the machine. Am i right in thinking there must be another reason?
"This may seem like a daft question but is it possible for a PC that is not switched on to be infected with a virus."
It absolutely cannot be infected when switched off.
What can happen after returning from a time away, is that the AV defintions will be out of date - and a new virus can *sneak in* before the update on the AV is done - especially if the forst thing one does is check email.
That's another reason that I trust NOD32 so much - it checks for updates on system switch-on - and every hour when running - so the chances of a virus sneaking in are virtually zero. Since it also guards against unknown viruses with exemplary heuristic checks too - that makes it even more unlikely than virtually zero :-)) click here
I agree with your views on how babybell got infected but I would just like to point out that NOD32 isn't the *only* anti-virus package that features heuristic techniques as McAfee also have it (which I use) and a few other anti-virus packages as well I presume?
Is the machine at work part of a network? It could be that your friend switched on the machine and a virus (that arrived on the network on the 10th) was sent once the machine was registered on the network. AVG then awoke. Or is your friend sure he is the only person using the computer!!?!
And there's no such thing as a silly question if you really want to know the answer.
"NOD32 isn't the *only* anti-virus package that features heuristic techniques"
Iknow that most AV packages have some form of heuristics (some disable it as standard due to performace hits!!). NODs heuristics are reckoned the best there is - have a look at their web-site about the Zotob worm! click here
