Are cashbars to paid surfing ok?

I have tried two different cashbars. The first one was Cashfiesta. It is a scam and it has been a scam for a long time, but when I installed it I didn't know that and it seemed like an easy way to earn some money. I used it for a while, but then I started reading some very negative reviews. Many people wrote that Cashfiesta accused them of cheating and refused to pay them. When I had read all of those reviews and bad experiences I decided to leave Cashfiesta. After some time I read about another cashbar and I installed that used it for a while, but I didn't earn much and I quit using that cashbar before I reached payout. Today I don't use any cashbars and I don't intend to install another one.

yes i have also heared about that,and many peoples are also working on it,i have also tried it but not found any result ....

In my opinion by installing "cashbars', we are giving chances to enter harmful sites too to computers. For some cash earnings we neglect security features of computer. Even cashbars that claim safe make computer slower.
