PANDA CLOUD AV scanned my whole 350 000 files computer in 2.5 hours to detect 3 viruses that were in fact FP (REVO UNINSTALLER AND SANBOXIE.EXE entries in the USERS/MICROSOFT folder) it wasn't able to neutralize. It's in the MICROSOFT FOLDER!!! It did neutralize 2 cookies. It interfered somewhat yesterday after the scan with MBAM and AVIRA on reboot but now everything is fine on my PC.
As for trying the v.590 of AVAST 5, I hear it's still Beta. I read many users reporting too many problems. Think I'm gone wait a while though it's been 6-7 months without AVAST now!
