No need to spread needless fear.
The link in the original post (the first comment on the topic) is safe. Has been for a long time.
You can check with virus total.
There are, however, a number of similarly named fakes being circulated around. As you can see here in the original file's relation tab on virus total there are quite a few.
Avoid all EXE files with differing sizes other than exactly 458,240 bytes. Also, check the checksums. The original file's SHA-256 hash value is: but you shouldn't listen to me and ask for the checksums from the original poster.
@VirosaGITS please do list the checksums in the first post of the topic so everyone can be at ease and avoid fakes.

Hey, I'm new to mining and lolMiner. Looking for some assistance.
So I got the cortex bat setup but I get the [Active: false (OpenCL init failure: Memory object allocation failure)] error on both my gpus.
I tried increasing the virtual memory to 16GB and then 32GB but that didn't work.
Any help is appreciated.
