I haven't had a problem with the Windows Infinitecoin and malware and my machine is secured in every crevice it contains. The OP should be careful making baseless accusations accusing one wallet over another, when it is quite obvious that the cause for the malware was 99% likely to be caused by something else.
If you're going to accuse one coin or another, post up proof or GTFO. Crypto has suffered enough this year without people like you coming along and damaging it further. By all means call out coins doing wrong by people, but make sure you don't defame them in the process if you don't have the proof to back it up.
Why would Tecshare who came along and helped resurrect this coin from the dead deliberately infect people with malware? What is the point if it would only drive away interest thus driving down the price of the coin. If the point is to get people to use a coin, you don't generate interest by infecting users. There is no logic in the OP's argument other than trying to draw parallels between a friends computer being infected and having the Infinitecoin wallet installed.
