My neighbor's computer cannot access the internet. Whenever we try to direct to msn.com (or anything else) we are redirected to http://browsersafeguard.com/Secure/Error?URL=http://www.msn.com/&ResponseCode=502 The following screen message is displayed [BrowserSafeguard] DNS Lookup for "browsersafeguard.com" failed. The requested name is valid, but no data of the requested type was found The system is Windows 7 64 bit We tried a system restore to 9/9 but it did not solve the issue. The restore window stated that the restore did not complete. The system was unable to extract a .dll file. The failure happens repeatedly. In one instance I was able to get to your website on her laptop and downloaded CCleaner. We ran it and deleted about 280MB of junk. However the failure continues. Is this a virus?
