Hi,

Either of these has been known to cause some issues, check with their support and/or
uninstall them as a test.

SPTD.SYS is part of Alcohol or DAEMON Tools and has been known to cause problems
though not usually as malware. If you do not use either then it is probably malware.

SPTD.sys

SPTD.sys

=========================================================

Antivirus/antispyware/security programs operate at a very low level so if there are any
programming mistakes they can cause a lot of issues. Unfortunately Kaspersky seems
to have joined that club. The fact that some have worked well for an extended period
means little as a recent change is all that is needed to cause or aggravate issues. Only
real way to test is to totally remove the ones in question. SAS, to me, is just too intrusive
and not needed in a good setup except as a on-demand scanner.

Hope this helps.
