Real-time scanning causes hangings in Visual C++ 6.0 [28849 & 28402]
Real time scanning may cause the computer to hang for a short period. To work around this
problem please add the following registry key ”HKEY_LOCAL_MACHINE\Software\Data
Fellows\F-Secure\
GKH2: NoLongPathExpand (REG_DWORD) = 0x1”.
Due to a problem with Microsoft Visual C++ 6.0 SP5 (or older) IDE saving a file with that
product may fail, Microsoft advises that the operation should be tried again, in case of a failed
save operation. This problem is fixed in Microsoft Visual Studio 6 service pack 6. For more
information see http://support.microsoft.com/default.aspx?kbid=822856.
Real-time protection always causes some overhead on file I/O, which can cause problems for
time-critical file operations such as creating CD-R/CD-RW images.

DeepGuard
DeepGuard Advanced Process Monitoring might cause problems with anti-cheating
systems for online games and software genuineness checking
It is possible that Advanced Process Monitoring conflicts with some 3rd party tampering
protection systems, e.g. anti-cheating systems for online games and software genuineness
checking. Turn off Advanced Process Monitoring from “Settings – DeepGuard” to resolve the
problem.
We appreciate if these compatibility issues are brought to our attention through support
channels.

DeepGuard doesn’t protect services in Windows 7 [65247]
When stopping a protected service from command line or from Services, DeepGuard fails to
prompt about it. However, it still protects services from most malicious stop attempts. This
problem only exists in 32-bit version of Windows 7.

Email Scanning
TLS- and SSL-encrypted e-mail protocols not supported [44173, 44869, 54496, 55285]
E-mail scanning only works with unencrypted e-mails using the protocols POP3, IMAP and
SMTP.
Scanning of e-mails encrypted with the Transport Layer Security (TLS) and Secure Sockets
Layer (SSL) protocols is not supported. E-mail scanning may either block all e-mails or fail to
scan the e-mails if the TLS and SSL protocols are used. If you are using either of the above
protocols for secure e-mail transmissions then e-mail scanning must be disabled.
