Hello MidgetMan,I used to be on Tiscali dialup and it was always slow,but mine was a bit faster than this one 4-5kbs.I think the three programs you mention should protect from virus and malware,but you should install a firewall as well ie.Zone Alarm:-click here;jsessionid=A1FhYWELHTDV9sW5Q0YllUTkDtgUAhmwapzuTnBnIIeF2kmBkdCA!1528543897!-1062696905!7551!7552!-1482804765!-1062696904!7551!7552?lid=nav_za
Zone Labs: or Sygate:-click here
Sygate Personal Firewall .After that download this little program:-click here
CCleaner - Crap Cleaner software download and run it this will clear your temporary internet files and lots of other rubbish,it,s simple to use and safe.
Hope some of this helps.Regards.
