Last night I went to check out the changelog of the lastest Memtest86 update and got some message about Redirecting / E-mail Spoofing or something. It's still doing it this morning.
hxxp://pcsupport.about.com/gi/o.htm?zi=1/XJ&zTi=1&sdn=pcsupport&cdn=compute&tm=64&f=00&su=p504.6.342.ip_&tt=4&bt=0&bts=4&zu=http%3A//www.memtest86.com/
I don't know if that link would be considered dangerous, so I modified the "http" just in case.
I ran an avast full scan last night after having been there and No Threat was found.
I guess if it WAS dangerous ... the avast Autosandbox would have been activated? Or not?
