Can you use different anti-spyware programs at the same time?
Peter Ross
This is a tricky one. It's best not to use two different anti-virus products at the same time. These tend to operate at a low level within the operating system, which can cause crashes, and the two programs can clash. Anti-spyware programs tended to operate at a higher level, as spyware was often browser related.
Nowadays, viruses are often distributed online and by fake codec downloads rather than by email, so the virus and spyware fields are merging, which makes mixing programs harder. But you can always try it and see how they get on.
In general, I think it's best to have one antispyware program running all the time, and run a different program from time to time, as a cross-check.
