How to find out whether it is the case of a false positive? It is easy enough, but maybe quite time-demanding. Terminate your work with all the applications, terminate the operating system and turn off your computer by the power switch. Turn it on again and start-up the operating system. Start the scanner that announced you the presence of a virus in the memory. If it does not announce its presence repeatedly, try to repeat the work (running of programs) which you were doing before starting the scanners, and after some moments start testing against viruses again. If even in this case no virus is found in the memory, it is a false positive.
AVAST32 thoroughly cleans all the used memory and what is more, all the information and virus samples it maintains only in a coded form. Only at the moment of testing it decodes the information on a virus, and having used this information it deletes it. It means that at any moment there can be not more than one decoded sample of a virus in the memory.
