XP-home SP3 IE6 OutlookExpress Dutch EAV 126.96.36.199 English (has happened too with EAV 188.8.131.52 English) Lots and lots of warnings like for example: D:\NOD32 EAV 4\Version 4_2_67_10\eav_nt32_enu.msi » MSI » !_Validation - decompression could not complete (possible reasons: insufficient free memory or disk space, or a problem with temp folders) So far it looks to me that the cause is the MS Malicious Removal Tool of Patch Tuesday in November 2010. I have tried to narrow it down to what is causing this, spending a lot of time to it putting back backup-images again and again; this is now the fourth time I am seeing it (first time after installing 184.108.40.206 and then re-installing the MS Malicious Removal Tool). It could be caused by other reasons: defrag in Safe Mode by the build-in MS defrag tool, or the fact that I still use IEClean 7 (formerly from Kevin and Nancy). But to me it seriously points to that recent last monthly MS Malicious Removal Tool. Without that latest MS Removal Tool, I don't get such a warning! I am wondering whether I am the only one seeing this....... This all happened when doing an in-depth scan with EAV. I am going to put once again a backup-image back, and then "disable" once and for all the monthly "MS Malicious Removal Tool", or whatever it maybe it called. I have absolutely zero time to look further at this: I urgently need to find a new appartment and that is far more important now for me.
