Jefoss,
I can assure you that all the programs on my list are free to download and free to use.
It would appear that you may have a browser hijacker on your computer that is taking you to fraudulent software sites.
The first thing to do is try to remove it with the Microsoft Malicious Software Removal Tool which will already be installed on your computer by Windows updater.
Go to Start -> Run -> type
MRT -> OK. Then run a quick or full scan.
See what that turns up.
Then have a further clean out:
1st thing to do is clear out all your temporary files, tool of choice is ATF Cleaner, it is free and you do not have to install it. Download and instructions
here
Leave Cookies unticked but select all the others and click Empty the selected.
Then download and save to desktop before installing
Malwarebytes AntiMalware
If you have problems installing it due to some malicious software preventing the install of any program that will kill it, right click the icon on the desktop and select 'Rename' and give it another name, anything will do, (DIY.exe) but end the name with .exe
* Double-click mbam-setup.exe (or another name if you had to rename it) and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to the following:
o Update Malwarebytes' Anti-Malware
o Launch Malwarebytes' Anti-Malware
* Then click Finish.
If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad. The rogue application should now be gone.
Reboot as required.
If that has cleared out the hijacker then you should be able to click on any item in my list and select a program and install it.
Post back.
