My Internet Explorer Cannot Connect to Secure Web Sites

dear rich,, clearing the tempoary internet files, and clearing the auto history, and restarting the router resolved the problem for gmail. gmail now can be opened, but hotmail, and other secure bank sites couldnt be opened. but again i tried opening gmail, its all back the same. again it couldnt be opened. any other things that i should try.?

If that does not work try another browser. Fierfox, Chrome, etc.

done everything as per your advice,,nothing changed, even chrome and internet explorer,, the same issue. any idea about how to change port 443 to my router??

Hello,

I agree with everything Rich has said, just may I ask, have these websites worked before on this computer, and was there anything that changes that might, just might have broken them?

Have you tried disabling your Firewall TEMPORARILY?

Richard

P.S. I would still recommend running Malwarebytes Anti-Malware Quick Scan, as MBAM has better heuristic scanning features than any other anti-virus program, including Kaspersky, and for Real-Time scanning like this, it may pick up something KIS missed. Though I don't think this is malware related, it can't hurt to look just a little deeper than KIS.

Dear niemiro, the recent thing i changed was the adsl wireless router, before i used one called "prolink": and now "d-link" . yes the websites were working fine in the prolink and dlink as well. at the beginning when i was starting to use the d-link router, i had problems opening sites like gmail,, bank websites, and all those secure websites. but when i restart my router and clear the temporary files, and clear the cache, and also running dir files as softpub.dll, it was working. but now none of the options were working again. so do you want me to run a Malwarebyte antimalware quick scan??and try?
