Even when you are Windows up-to-date and have the latest Virusscanner+Updates
It gives you absoluteley NO WARANTY that you are safe!
I got 2 times infected and my Scanner was bypassed (Avira Antivirus, Windowsfirewall) i switched to AVG now.
(as a user with over 15 years expierience, finally i know that i was infected so there was no damage only time consuming reinstalling.
I have an seperate PC just for Internet without sensitive Files).
Also most users surf with admin-rights so a Virusscanner is an easy opponent for the most
worms/trojans...
Also the problem of new trojans, which use securityholes where actually
no fix exists and no Antivirussignatures are aviable.
Read the Wikipedia article about Stuxnet trojan, how powerfull trojans are today and will be in the future...
Also the Google Image search is a big Trojanthrower, they "need" javascript on, but exact that is why
the trojans come to the users. I dont use it anymore. (you get a virus by watching normal pics, no porn or similar is needed xD)
- - So this is not a solution. The Security Center is not able to secure the Bitcoind Money- -
i link to my thread where i discuss a real Solution for this:
