Thanx for the answer. I tested a couple of antiviruses / anti-spywares etc and I think that the system is clear of viruses now. The links of the programs that do not run are not deleted, since if I try run some program manually (e.g. sygate) I get no link error (the link exists), but simply the program never starts.
