X.x that sucks, why don't hackers have anything better to do? It's like when spammers kept hacking TIMGUL site in 2008 until we switched to SMF, i had to check my FTP every day so my host won't suspend me for bad files.
I never had any issues regarding my own computer getting hacked, though, but again I always had latest Windows updates, antivirus and firewall activated. If you use an older version of Windows, like 95, 98, 2000 or even ME, then it could be an issue, though, since these are no longer maintained. Same if you download torrent/warez, some files will be claimed as clean, but they just hide viruses that will be discovered like one or two years later, then it will be too late as the virus will have damaged your computer files alerady. I generally keep backups of my important stuff like on a file hosting, USB flash drive, DVDs, CDs or another computer now, in case. But still, I wish people had better things to do than do harm to people.
Please don't give up, though, I would like to see your show at one point and from what I remember in an old topic of yours, if I read carefully you alerady had a big audience, right? I wouldn't be surprised if many people are interested in listening/watching it again if they like non-commercial music.
