Hi,

While scanning for viruses on my PC I got
a notification from my Avast antivirus scan
that upx.exe was a virus. To check, I looked
up upx.exe and see that it is an exe compression
tool. Does anyone know if the 2.2.2 Go32v2 target has a corrupted upx.exe file embedded in it?

I'm thinking there may be nothing wrong.

regards,

R. Batey

It's probably a false positive. Virus scanners often don't trust program packers due to the techniques they use. And the Dos version of upx is probably rare enough for it not to have been added to some exception list.
