It seems that every time i click on a link in a email i get an error message saying: windows cannot find "URL" Make sure you typed the name correctly, and then try again; but firefox still opens to the page anyway. I read some posts on google that said it could be a virus...Does anyone know anything about this error? Thanks.

are you using outlook when this thing happens or what ? well if you suspect it's a virus..worth trying to scan your system..try downloading malware bytes...and scan your system :)

I am using windows mail, that vista comes with. I will try a scan, is malware bytes completely free?

May be effected by the virus..

You could also try AVG. There is a free version and if update is reasonably effective.

i am yet to do the registry clean.

You could also try Advanced Windows Care by IObit. It covers temp files, spyware, reg scan and privacy in one sweep. You could also check for any updates for Vista's mail at Microsoft

I got "Windows cannot find" errors on each windows mail link inside of emails until i stumbled upon the fact that my firewall was turned off. It still opened the link but that blasted box popped every time. When i turned the firewall on, the link opens without the Windows cannot find box. It was repeatable. Apparently, the firewall being turned off causes the external windows mail link error box to pop.
This is not caused by a virus.
