Welcome to Lockergnome.
Please try to follow the steps outlined
here. If you have problems accessing any of those sites to download the files, do the following and it should fix the problem:
Right click on My Computer and go to Properties. Then go to the Hardware tab and click on Device Manager. Go to View > Show hidden devices. Then go to Non-Plug and Play Drivers and expand it. Look for TDSservs.sys and when found, right click on it and choose Disable. See if you can download the security programs now.
