I am using a 64 bit Toshiba laptop, running Vista. Initially, we had a free subscription to Norton. When that ran out, I uninstalled Norton, and installed Avira free instead. The problems seem to date from about that time.
This computer has a wireless connection to a network. The connection is reported to be strong, but...
Internet download starts quickly, then slows, and stops.
Microsoft auto-update or manual update stalls and has not updated since September.
An attempt to run housecall seemed to work, except that the update file download stalled stopped at about 40% or so.
Same thing happened when attempting to install Microsoft Security essentials - program installs, but definitions update stops loading at about 30% or so.
I have uninstalled Avira to install Security Essentials, but when Avira was 'active', it appeared to run normally, and even auto-update. However, when running the Vista Health report, all systems including security came up 'green', however the contradictory message of 'no antivirus software present' came up as a warning.
An attempt to install AVG also stalled when attempting to install updates. (I downloaded the program with a different computer - I could not download the program here.
The new A-squared 1 Mb file to check whether the system had any infection disconnected the internet connection, then complained that an internet connection was necessary to run the program.
Oddly enough, the computer appears to run fairly normally in other respects, with word, power point, videos, etc. However, streaming videos and anything else requiring a download of any reasonable size stalls.
I downladed and ran a file called DDS.scr, after seeing it mentioned on one of your posts, and have saved the two resulting files.
That's where we stand now. What is most frustrating, is that no recovery disk was made for the system when the computer was first set up. :-(
Can you help??
