Didnt look at it that way MeyerSurprisingly, that has never been a real issue. The larger 'pirate' sites seem to do a good job of policing their sites and those sites that they link too.
If you use the internet very much, it is wise to have, not only an excellent anti-virus program on your computer, but also a very good anti-malware program anyway. Malware seems to be the bigger problem currently.
I have been frequenting these 'pirate' sites for almost 10 years and have only had few instances where Malware was detected and no virus detection in over 5 years. Since these sites rely on advertising dollars (many have the same advertisers as Network TV), it is in their own interest to keep their sites 'clean'.
We have the AGV security system on our PC and the same system on the Laptop.
It has an active malware and virus system built in and will actively let me know when to remove threats
