I'm sure that many Softonic downloads are trouble free; unfortunately one of mine was not, and Google recently reported :
What is the current listing status for softonic.com?
This site is not currently listed as suspicious.
What happened when Google visited this site?
Of the 29048 pages we tested on the site over the past 90 days, 0 page(s) resulted in malicious software being downloaded and installed without user consent. The last time Google visited this site was on 2012-12-17, and the last time suspicious content was found on this site was on 2012-12-16.

So, treat with caution, but do not assume that most or all downloads are dangerous.
