Hello Avast forums, i've started to notice a really strange behavior last night: whenever i right-click in windows explorer, it crashes. I imagined it was the usual context menu problem, so after using ShellExView it fixed for a while, but now it's happening again. Also when attempting to perform a CCleaner registry clean-up, it freezes when searching on the categories "ActiveX/Class entries and MUI cache". Also my Avast antivirus didn't detect anything. Could this be some sort of virus? Please help me.
Thank you in advance, John S. Beyer
