I still have old version of NOD32 (ver. 2.7) and I am thinking to upgrade it to ver. 4.2. But I also have running Spy Sweeper 5.5 on my computer. It looks like NOD32 ver. 4.2. can perform antispyware protection, and I am wondering if NOD32 ver. 4.2. is compatible with Spy Sweeper. Do I need to have them both, or new NOD32 is enough to protect a computer from spyware and malware threats? I can not say that I like Spy Sweeper very much, but it worked pretty well in several cases when NOD32 ver. 2.7 did not work.
