Today I noticed a pop-up from the Windows 7 Action Center showing that Win 7 AntiMalware was turned off. I thought that was a bit strange, so clicked to turn it back on, after which it did a scan showing that I had 29 files with spyware in. I didn’t think this was too good(!), but was a bit confused by the options saying that I could purchase the full version of AntiMalware. I was under the impression that it was free, but clicked the link to see what would happen. It came up with a very official looking page at nationalsecurityorg.com (although the address bar was hidden) asking me to pay for Windows Defender 2010. I was sure that Defender was a free product, so did a search and found out that Win 7 AntiMalware is itself malware.
I followed the instructions to remove it that I found at 2-viruses.com. This seemed to get rid of AntiMalware, however it also screwed up the association of .exe files in Windows, meaning that I couldn’t actually run any programs! After a slight panic I used Anna’s PC to lookup the solution, and thankfully found info at SevenForums on how to resolve this – they provided a .reg file to restore the settings in the registry. Microsoft also provide a way of resolving this.
I’m now running a full scan with Windows Defender to check if it can find anything else. Bit annoyed that it didn’t detect the original problem, might have to find an alternative.
