I have picked up either a virus or some malware that frequently redirects my browser to intermediate sites. Stopzilla calls it MalPac.D but repeated attempts to remove it with Stopzilla have failed. I tried to update my antivirus (Bitdefender) but every time I try to download it I get a message that the installer files are corrupt and the install fails. I installed a different antivirus product that also found some viruses and removed them but the redirect is still there. I can go into tools>options>advanced>settings>advanced and find that there is a manual proxy server selected. If I just click on "No Proxy" the proxy setting will reset itself. If I just click on "No Proxy" and delete the info for the proxy server I can then do searches without redirects. Any idea how I can find and get rid of the redirect virus/malware?
