"Not so sure anymore"2.5 starson by mrkirbyv
Pros: Not a resource hog, appears to work well
Cons: Slows down login time, unreliable updates
Summary: I have been using PC-cillin for about 3 months now, and have been relatively happy with it, especially when compared to Norton and Panda that I previously used.
It was an easy install and seems to not interfere with applications as much as some others. Scans quickly, doesn't noticeably affect mail or interent browser speeds. Does slow down login and logout slightly. Updates are convenient.
However; Apparently Friday night an update was pushed which caused my laptop to lock up upon login. After several hours of debugging, I relented and started reloading XP and applications. Last night I ran across a thread on a listserver indicating there was a bad file pushed by Trend that caused a problem for many users including me. Trend never notified the registered user base of the problem. I find this unacceptable for an antivirus software vendor. Not only did they disable my computer but they failed to tell me after they realized the problem, leaving the diagnosis and fix to chance. Yes, they published a fix on their support site Friday night but who would have figured an antivirus would cause a freeze on login? They have lost my trust.
