While downloading and installing WinRAR from CNET (i trusted the site), a spyware called Trenderia was also installed about two weeks ago. I immidiately uninstalled WinRAR and ran Trend Micro PC-cillion internet securty to check virus and spyware and delted almost 50 infected files. then i installed other spyware softwares - Malawarebytes anti-malaware and Lovasoft's Ad-aware Free 2008 pro, each detected some more infected files, and removed, then uninstalled these softwares as i heard it would not be effective if there are two or more anti- virus, anti-malaware, anti-spyware softwares. Since then I have not visited any such websites except very trusted sites such as sajha, mysansar, etc. Still my security software finds 10-15 infected files in each time of scanning. How would I get rid of all of the infection?
Another problem is that, due to infection, the websites youtube and bbc are redirected to some websites of viruses, or spyware itself blocked these websites so that I would install some spywares and I get the message like this (screen print), which is fake message in the name of Microsoft Security Center. How do I correct the path if it is redirected or corrupted in some files? Thanks for your help in advance.
