Here's what you should start with:

import urllib2
from bs4 import BeautifulSoup

URL = 'http://www.pcwelt.de/download-neuzugaenge.html'

soup = BeautifulSoup(urllib2.urlopen(URL))
links = [tr.td.a['href'] for tr in soup.find('div', {'class': 'boxed'}).table.find_all('tr') if tr.td]

for link in links:
    url = "http://www.pcwelt.de{0}".format(link)
    soup = BeautifulSoup(urllib2.urlopen(url))

    name = soup.find('span', {'itemprop': 'name'}).text
    version = soup.find('td', {'itemprop': 'softwareVersion'}).text
    print "Name: %s; Version: %s" % (name, version)

prints:

Name: Ashampoo Clip Finder HD Free; Version: 2.3.6
Name: Many Cam; Version: 4.0.63
Name: Roboform; Version: 7.9.5.7
...

Hope that helps.
