First I tried GUIMiner-scrypt and then cgminer-3.9.0-windows.zip
Both archives are marked as malicious in Google Chrome. I googled and have not found articles about that. Do other people get such warnings while downloading miner?

UPDATE
My links are 2 top google results
@TinS gave another download link and file is name is same guiminer-scrypt_win32_binaries_v0.04.zip but size is different.
One file is marked as malicious by Google Chrome and another not.
1I think the tag "malware" covers it sufficiently and we don't need a "malicious" tag additionally. – Murch – 2014-01-23T13:27:31.203
Google Chrome tells
maliciousI addedmalwaremyself just because there is such tag. – Max – 2014-01-23T16:22:24.103That's exactly what I meant: "malware" by itself is recognizable and descriptive. On the other hand I don't see how "malicious" could ever stand as the only tag of a question, as it could refer to anything. – Murch – 2014-01-23T17:31:27.360

The first site has fine print that says says "This site is not the official page of the software." I'd be very suspicious of that download. https://bitcointalk.org/index.php?topic=150331.0 seems to be a more reputable place.
– Tim S. – 2014-01-23T18:33:40.033The one I downloaded from your link is not marked as malware. My links are top results in google and google mark then as suspicious. Also virustotal give 18 warnings
@TimS. Thanks
2I'd bet the reason Chrome marks it as malicious is the same some anti-viruses mark scrypt miners as malicious: since scrypt can be mined with CPU, botnets galore attach a CPU-scrypt-miner as payload to put the computers they control to mine for their manager... – Joe Pineda – 2014-01-24T01:34:11.940
